Également disponible en français sous le titre Évaluation et Rapport de situation du, Generation time (average age of parents in the population). Abundance data collected by general large–scale bird monitoring programs from the Canadian range are too sparse (only a few detections on BBS, FBMP and OBBA2 point counts) to be used to calculate a meaningful estimate of the Canadian population. Reproductive success of Acadian Flycatcher in the Blue Ridge Mountains of Virginia. Little is known about the migratory behaviour of this species (Whitehead and Taylor 2002). [accessed 25 October 2008]. In Ontario, this species is typically found either in large patches of mature deciduous forest or in mature, forested ravine settings, and has a demonstrated susceptibility to forest loss, fragmentation, and degradation.

This species is also presently listed as Endangered, Schedule 1 under the federal Species at Risk Act and the Ontario Endangered Species Act 2007. It breeds in eastern North America, and winters in Central America and northwestern South America (Figure 1). On a finer scale, habitat degradation has been observed at several Acadian Flycatcher sites due to heavy logging, the spread of invasive alien plants, and new house construction (Recovery Team data). 2000; Friesen et al. However, habitat shift for species associated with mature forests, such as the Acadian Flycatcher, is predicted to occur relatively slowly (at least one century), due to the lag time associated with tree migration and longevity (Matthews et al.

Journal of Field Ornithology 80:234–241. However, it will take many decades before such habitat reaches sufficient maturity to support Acadian Flycatchers. The Acadian Flycatcher is protected under the federal Species at Risk Act (SARA). 2005). Bradstreet, G.S. Climate threats facing the Acadian Flycatcher. With small flycatchers, including this species, vocalizations are best for identification. PLEASE NOTE: Not all COSEWIC reports are currently available on the SARA Public Registry. The Acadian flycatcher breeds only in North America, primarily in the eastern half of the United States where the species is widespread and common. Least flycatcher (E. minimus) has lighter-colored undersides. It is listed as endangered by COSEWIC. A preliminary population and habitat viability analysis for the Acadian Flycatcher in Ontario suggested that the Canadian population is not self–sustainable and may become extirpated without a continuous influx from external populations (Tischendorf 2003). Summary Report, Contract # KW404–07–0824. songs, or to fly out to catch insects. Technical Series No. Of the dozen or more maddeningly similar species in the Empidonax genus, the cheery Acadian Flycatcher is the common one of mature forests of the Southeast and Mid-Atlantic U.S. Forest cover within the breeding range of this species in Ontario has not exhibited similar recovery trends to those in Northern New England over recent decades. COSEWIC assessed this species as Endangered in November 2000. 2006. BBS long–term trends for Ohio and Pennsylvania over the 1966–2007 period show declines of 2.3%/yr (p=0.04, n=53), and 0.4%/yr (p=0.28, n=78), respectively (Sauer et al.

The study predicted a 93% risk of extirpation after 100 years, given a starting population size of 30 breeding pairs and no immigration. It was considered a fairly regular but rare spring migrant at Prince Edward Point (Lake Ontario), with several records between 1976 and 1986 (Weir 1989); however, this species has not been reported there in recent years (Prince Edward Point Bird Observatory unpublished records 2001–2008). The effort–adjusted probability of observation for Acadian Flycatcher in Ontario increased significantly (by 86%) between the first (1980–85) and second (2001–2005) atlases (Cadman et al. However, the conclusions should be viewed as preliminary, because the study was based upon limited data and conservative estimates. 24–28 in Kettle, A. University of Waterloo Press, Waterloo, ON. website: [accessed February 2009]. However, a more recent meta–analysis of area and edge effects found that its occurrence is consistent with edge–avoidance and that it does not show significant patch–size effects (Parker et al. There is currently no evidence of spatial population structuring within the Canadian or North American population of this species. [accessed 25 October 2008]. Federation of Ontario Naturalists. 20. Quick Links: | Empidonax virescens. Rustay, J.M. Total survey effort in each of these coordinated surveys was similar, although there were differences in the sites covered. Bird Studies Canada, Port Rowan, ON. Throughout its breeding range, the Acadian Flycatcher is a habitat specialist, nesting in mature closed–canopy forests with an open understorey. Heagy, A., and D. Badzinski. The Second Atlas of Breeding Birds for New York State. 2000. Carolinian Canada Coalition and Ontario Ministry of Natural Resources. Are there extreme fluctuations in number of locations? 2005). The breeding biology of the Acadian Flycatcher has been studied intensively in the United States. 2007. The Acadian Flycatcher’s breeding habitat has been broadly characterized as large, mature forest tracts associated with water. Acadian Flycatcher, pp. For example, until recently, flowering dogwood was a fairly common shrub in parts of southern Ontario within the Acadian Flycatcher’s primary breeding range. K1869–2–0070.

This could also be an Alder or Willow Flycatcher. The most recent population estimate counted 20 to 30 pairs of birds. Acadian Flycatcher (Empidonax virescens) Status in Canada: Endangered. Outside of the breeding season, this species uses a broad range of habitats, but deforestation on the wintering grounds is a potential concern (Whitehead and Taylor 2002). 2009). There are also some summer records of territorial males at the Long Point and Big Creek National Wildlife Areas, but these are believed to have been unmated birds (J. McCracken pers. Bird–Banding 37:227–257. Acadian Flycatcher online maps (provisional data). Studies of Acadian Flycatcher occurrence and breeding success in the United States have shown that it is sensitive to site–, patch– and landscape–scale effects. Acadian Flycatcher (Empidonax virescens) in NatureServe Explorer: an online encyclopedia of life [web application]. Regardless, nests are nearly always suspended from the forks of lateral branches that extend more or less horizontally from the trunk; this particular growth form is a key feature of all the aforementioned species favoured by nesting Acadian Flycatchers (J. McCracken pers. These programs involved monitoring occupancy at known sites and searching areas of suitable habitat using a combination of knowledgeable volunteers and experienced contract staff.

The bird lives in the understory of woods with a closed canopy. Within a physiographic region, this species exhibits a high degree of habitat specificity at various scales (Bakerman and Rodewald 2006). Butcher, D. Demarest, R. Dettmers, E.H. Dunn, W. Easton, W.C. Hunter, E.E. Committee on the Status of Endangered Wildlife in Canada. The Acadian Flycatcher occurs within Long Point Wildlife Area, which is federal land protected under SARA. The Acadian Flycatcher is often used as a focal species for forest bird research in eastern North America because it is considered relatively easy to study, and is an indicator of forest habitat conditions at a range of scales. comm. Acadian Flycatcher in Ontario. Whitmore. Status historyDesignated Endangered in April 1994. Collectively, these threats to habitat greatly reduce potential for rescue from adjacent U.S. populations. About half of the known Acadian Flycatcher sites in Ontario are on publicly owned lands, but most of these sites are working forests that are being actively managed for timber and fuelwood production (Recovery Team unpubl. The species is threatened by forestry practices, particularly those that target removal of large trees. Journal of Field Ornithology 70:514–519. Online Version 6.3.2, Updated December 2008. This was followed by a trend of reoccupation of its former range starting in the 1960s, likely facilitated by maturation of second–growth forests in the northeastern United States (Whitehead and Taylor 2002). 1994. The 2002 southern Ontario Hooded Warbler/Acadian Flycatcher survey. The Acadian Flycatcher is a small migratory songbird. 2005. The Acadian Flycatcher has been known to migrate to Ontario for well over a century with the first nesting records dating back from 1884. Status at SWCR: Rare breeding bird. [Accessed September 2008]. Despite its similar appearance, the genetic signature of the Acadian Flycatcher is strongly differentiated from other Empidonax species and it is considered a separate single–species clade within this taxon (Zink and Johnson 1984; Johnson and Cicero 2002). Endangered and threatened species; Extinct species; Unaccepted species; News & updates; ACADIAN FLYCATCHER. 2006; Chapas–Vargas and Robinson 2006; Chapas–Vargas and Robinson 2007). 128 pp. 2003; Heagy and Badzinski 2008). This includes deciduous forests in the eastern United States west to Texas. It is also protected by the federal Migratory Birds Convention Act. 2009). It is often found in well-wooded swamps and ravines. However, the number of sites occupied in any given year has been fairly stable.

The Hooded Warbler is listed as Threatened nationally under the Species at Risk Act and Special Concern provincially under Ontario’s Endangered Species Act, 2007. Habitat within the existing forest patches is also degraded in that most forests in southern Ontario are exposed to logging that targets the removal of mature trees. The supply of mature, closed–canopy, open–understorey, interior–forest habitat is a limiting factor in many parts of its range, including southern Ontario. Nests with a cowbird chick rarely fledge any Acadian Flycatcher young (Whitehead and Taylor 2002). 2006; Rodewald and Shustack 2008). Population is generally secure across most of.

Although annual site occupancy is somewhat intermittent in Ontario owing to natural turnover of individuals, the species displays strong long–term attachment to particular sites, and routinely recolonizes them so long as they retain favourable breeding habitat. Ottawa. National Recovery Plan No. Acadian Flycatcher — Photo courtesy of Ron Ridout. Nevertheless, the survey data can be used to estimate the size of the Canadian population.In the 2007 surveys, 36 Acadian Flycatcher males were found at 25 sites in six counties/regions (Table 2); Heagy and Badzinski 2008). [accessed October 2008]. Available information suggests that the Acadian Flycatcher population in Canada has been relatively stable over the past decade, and stable or increasing modestly over the past few decades. Several core breeding locations have been monitored more frequently, with more intensive studies involving nest monitoring, colour banding, and territory mapping projects carried out in some years (Martin 2001, 2005; Woolfenden and Stutchbury 2004a,b; P. Burke 2006, 2007). Alan Dextrase, Ontario Ministry of Natural Resources, Peterborough, Ontario. In addition to the distinctive peet–sa territorial song, males and females have other characteristic vocalizations that can provide clues as to breeding status and nest locations. 1994).

The female typically lays 3 eggs in a cup nest suspended from the outer branches of a tree, at a height of 3 to 9 m. Pairs will usually re–nest if a nest fails and will sometimes nest again after having a successful nest. Nests in Ontario and elsewhere are situated 3 to 9 m high in small trees, saplings and shrubs (Friesen et al. Breeding season records from northern New England since the 1980s indicate an expansion of the historic breeding range in the northeastern United States (Whitehead and Taylor 2002). The incubation period is about 14 days; incubation and brooding is by the female only. The Committee meets to consider status reports on candidate species.

There is no information on its distribution in Ontario prior to the late 1800s, by which time the landscape of southern Ontario had been radically altered by the conversion of the extensive woodlands and wetlands to agricultural cropland and pasture (Austen et al. Beck, D. Lepage, and A.R. Regional forest cover is below the 30% minimum guideline for sustaining forest bird biodiversity (Environment Canada 2004) in all parts of the Carolinian region, and is less than 5% in some parts of the region.

However, the response to these factors is not always consistent across the breeding range, possibly because these site and edge effects can be masked by the impact of more pervasive landscape–level effects (Robinson and Robinson 1999; Bell and Whitmore 2000; Hazler et al. November 2008. Nest predation is the most common cause of nest failure. The 95 nesting attempts tracked in Ontario for the 2001–2004 period fledged an average of 1.7 young per female per year (Table 1). 2000. Most of the increase in forest cover in southern Ontario over the 20th century was in the Lake Simcoe – Rideau region. The forests within the Canadian breeding range of this species are highly fragmented, with two–thirds of all forest patches being less than 5 ha, and with only 431 patches being over 100 ha in size (Flaxman 2004). Conservation Biology 13:58–66. The current extent of occurrence (EO) of the Acadian Flycatcher in Canada, as delineated by the range envelope polygon described by occurrences reported during the 2001–2005 Atlas project (Figure 2), is approximately 36,500 km². Mulvihill. The Acadian Flycatcher is protected in Canada under the Migratory Birds Convention Act (MBCA 1994). 2008; Rodewald and Shustack 2008; Rodewald 2009).

As with other small passerines, the expected life span is short, and the generation time (average age of breeding adults) is likely 2–3 years. Fauth, P.T. Although the population appears to have been relatively stable over the past 10-20 years, this is most likely due to immigration from U.S. populations. Lambert, L.R. comm. However, given the consistency of past survey results, it seems probable that about half of all occupied sites were included in the 2007 surveys. The Acadian Flycatcher is listed as Endangered federally and appears on Schedule 1 of the Species at Risk Act. Almost all atlas squares (10 x 10 km) in the Carolinian and Lake Simcoe–Rideau atlas regions in southern Ontario received some coverage in both atlases and most received more than 20 hours of coverage. Its ability to use different nest trees may be important because some of the preferred nest tree species (e.g., hemlock and beech) are being decimated by invasive forest pests (Hemlock Wooly Adelgid, Adelges tsugae, and beech bark disease, Nectria gallingea) in the northeastern United States, and similar tree mortality is expected to occur in southern Ontario within the next decade.

Male Acadian Flycatchers, Empidonax virescens, obtain extra–pair fertilizations with distant females. Stats. None of the 156 Acadian Flycatchers banded during migration in Canada from 1955 to 1995 were encountered elsewhere, and no foreign banded birds were recovered in Canada during that period (Brewer et al. Atlas of the Breeding Birds of Ontario, 2001–2005. Other tyrant flycatchers. The northern range limit extends from southeast Minnesota, across southern Wisconsin, southern Michigan, southwestern Ontario, and western and southeastern New York (Whitehead and Taylor 2002). Federation of Ontario Naturalists, Don Mills, ON and Long Point Bird Observatory, Port Rowan, ON. That said, in Ontario, this species appears to do well in long, linear, forested ravine situations that may be no more than 100–200 m in width. In ravine settings, nests are located near (often over) a stream. Acadian Flycatchers look like other members of the Empidonax group of flycatchers; however, its larger size, more olive-green colouration, and longer tail can be distinguishing features. The current Canadian distribution represents approximately 1% of the total global breeding range. 1999. Reasons for designation:In Canada, this species is restricted to certain types of mature forest in southern Ontario. Iverson, and A.M. Prasad. Are they endangered? Ontario Partners in Flight Ontario (OPIF). These influxes may double the population in some years (Friesen et al. Speirs,J.M. Reduced productivity due to degraded habitat conditions (especially due to low regional forest cover, and high fragmentation) on the breeding grounds. 2007). Widespread agricultural drainage has also dramatically altered water tables and moisture regimes. The breeding range of this species corresponds closely to the Eastern Avifaunal Biome, being widely distributed in forested landscapes east of the Great Plains (Rich et al. 24 September 2007.

Get Started. the BEAUTIFUL acadian flycatcher is CURRENTLY an endangered species in ontario. ONRS (Ontario Nest Record Scheme) 2008. The atlas map suggests a northward range expansion beyond the Carolinian region over the 20–year interval between atlases (Martin 2007), but the degree to which this is true is complicated by a concurrent increase in search effort and a general improvement in observer skills. NatureServe. 2009). However, as Martin (2007) notes, much of the recent increase can be attributed to directed searches carried out by experienced field biologists working on behalf of the Recovery Team rather than an actual increase in numbers. Parasitism rates in the US range are highly variable across landscapes, ranging from 0% in areas of continuous forest, to 3%–7% in areas with high forest cover, to 20%–50% in areas with less than 30% forest cover (Whitehead and Taylor 2002; Fauth and Cabe 2005; Hazler et al. 986 pp. Extremely similar to several other species, especially Alder and Willow Flycatchers. In Canada, the Acadian Flycatcher occurs in very low numbers in the Carolinian area of southern Ontario. Woolfenden, B. and B. Stutchbury. The bird reaches maturity at one year and has a lifespan of up to 10 years. In Canada and Ontario, the Acadian Flycatcher is ranked as Imperiled (N2B and S2B; NatureServe 2008; NHIC 2008). Forest configuration is also a concern because Acadian Flycatchers are sensitive to forest fragmentation effects. Return rates of breeding birds in the US range from 18% (n=234) in fragmented forests in Indiana, to 45% (n=31) in forest fragments in Michigan, and 52% (n=52) in continuous forest in Virginia (Walkinshaw 1966; Whitehead and Taylor 2002; Fauth and Cabe 2005). Smith, C.R. 688 pp. Between 1997 and 2007, Acadian Flycatchers were recorded at 60 sites. Robinson, W.D. Even so, forest fragmentation and urbanization are adversely affecting habitat quality in many parts of this species’ breeding range, including the Great Lakes states bordering Ontario. Cornell University Press, Ithaca, NY. Studies of the Acadian Flycatcher in Michigan. The Acadian Flycatcher is also listed as Endangered under Ontario’s Endangered Species Act, 2007 (ESA; Ontario Ministry of Natural Resources 2008a, b). Acadian Flycatchers are habitat specialists, nesting in mature closed- canopy forests with an open understorey.

Acadian Flycatcher populations remained roughly stable between 1966 and 2015, according to the North American Breeding Bird Survey. Although large, fairly stable populations occur in the United States, there is recent concern that populations in the northeast will experience substantial declines resulting from the loss of preferred nest tree species (especially Eastern Hemlock, American Beech and Eastern Flowering Dogwood) owing to recent outbreaks of invasive insects and epidemics of forest pathogens. It is very similar in appearance to other Empidonax flycatchers, and during the breeding season is best distinguished by its distinctive peet–sa song, other characteristic vocalizations, and habitat. 2005.

This species is considered a focal species because it is relatively easy to study and because it is considered a sensitive indicator of habitat conditions at a range of scales. Status in Ontario: Endangered. 2004; Sauer et al. McNicol, D.W. Mehlman, B.E. Stutchbury, B., pers. Predation is the main cause of nest failure in Ontario (Table 1) and elsewhere. It arose from the need for a single, official, scientifically sound, national listing of wildlife species at risk. IAO is <500 km², but there is no evidence for decline, fragmentation or extreme fluctuation in populations, habitat or range. During the breeding season, males develop a distinct cloacal protuberance and breeding females have a well–defined brood patch (Pyle 1997; Wilson 1999; Whitehead and Taylor 2002). Final Report – Contract No. Are there extreme fluctuations in number of mature individuals? The species was designated Endangered by the … The Acadian Flycatcher is a small migratory songbird. (2009) predicted a significant decline in Acadian Flycatcher populations and range contractions in the northeastern U.S., particularly in the Appalachian Highlands, owing to large–scale mortality of hemlock from wooly adelgid infestations. Matthews, K.P. Assuming that half of the eight males detected only once were migrants or transients and that no birds were missed at any of the survey sites, then the minimum number of territorial breeding males was 32. Several municipalities have designated significant wildlife habitat, significant woodlands and valley lands in their Official Plans. The productivity of the population in southern Ontario is adversely affected by degraded habitat conditions, particularly low regional forest cover and high forest fragmentation. 2008. NatureServe, Arlington, Virginia. The Acadian flycatcher breeds only in North America, primarily in the eastern half of the United States where the species is widespread and common. It winters in Central America and northern South America from Nicaragua to Ecuador and Venezuela. Kennedy, A. Martell, A. Panjabi, D.N. Johnson, N.K.and C. Cicero. Search effort in forested areas north of the Carolinian region has been largely limited to coverage by atlas and other volunteers. Lawrence Plain (North American Bird Conservation Region 13), Priorities, Objectives and Recommended Actions. Urban–associated habitat alteration promotes brood parasitism of Acadian Flycatchers. The Acadian Flycatcher was designated as "Endangered" Species in 2000 by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). The Canadian population is at the northern limit of the species’ breeding range, the edge of which is presumably limited by climatic tolerances because apparently suitable forest habitat is extensive farther north outside the current breeding range (Deschamps and McCracken 1998). As new sites are discovered, the total number of known sites has gradually increased. Matthews, S., R. O’Connor, L.R. The PPSalso provides some protection to forests, including enabling municipal tree–cutting bylaws, and providing protection for designated significant woodlands and valley lands. Northeastern Naturalist 15:227–240. Its range extends north to the Great Lakes and southern New England, and it has been gradually expanding this range toward the north.

Since that date to mid-September 2020, four species have been added through eBird. Serious conservation concerns, both in Canada and the adjacent U.S.also stem from increasingly widespread losses of a variety of favoured nest tree species owing to the spread of an array of exotic forest insects and pathogens. The Acadian Flycatcher population in Canada is very small and annually occurs at no more than about 20 sites scattered across a relatively large area (35,000 km²). Strong site fidelity has also been reported on the wintering grounds (Whitehead and Taylor 2002). Heagy, A., D. Martin, and J. McCracken. Website: [accessed 14 October 2008].

Edge–avoidance seems to be less of a factor in forested ravine situations because it will nest in long linear territories that occur in quite narrow (minimum of 80–85 m) belts of riparian forest corridors (Friesen et al. 2000; Martin 2007). 1989). Nests located near forest edges, roads, or urban development are generally less successful and produce fewer young than nests located in higher–quality habitats, such as in the interior of a large mature forest more than 600 m from the nearest edge. SARA Status: Schedule 1, Endangered Image of Acadian Flycatcher Top Description The Acadian flycatcher is an olive-green songbird with a long and slightly forked tail, white wing bars, and a yellowish belly. In Canada, the Acadian flycatcher occurs in very low numbers in the Carolinian area of southern Ontario. The information on the abundance and productivity of Acadian Flycatcher in Ontario used in this status report is the result of the work carried out under the direction of the national Acadian Flycatcher/Hooded Warbler Recovery Team (especially field work carried out or directed by Debbie Badzinski, Dawn Burke, Peter Burke, Lyle Friesen, Dave Martin, Jon McCracken, Bridget Stutchbury, and Bonnie Woolfenden).

The best available information on the extent of forest cover for this region is Ontario Land Cover mapping, which uses classified Landsat 7 satellite imagery collected between 1999 and 2002 (OMNR 2006). Acadian FlycatcherThe Acadian flycatcher is a small flycatcher. Its breeding habitat in Canada is important to many other species at risk. Infestations are currently only about 200 km from Ontario. In size, it is slightly larger than a house sparrow, and in appearance it is similar to other flycatchers of the genus Empidonax. These additional sites include historic sites that have been re–occupied, previously unoccupied sites that have been newly colonized, and birds found at sites that have not been previously surveyed. Date of Listing (yyyy-mm-dd): 2003-06-05. Bakerman, M.H. NS. The above percentage figures do not necessarily represent the actual relative importance of individual tree species, because the high use of species like hemlock and flowering dogwood was only recently discovered during special search efforts by the Recovery Team in the last decade or so. 1999).

Prior to the 1970s, this species was considered a rare but fairly regular local breeder along the north shore of Lake Erie (Speirs 1985; Godfrey 1986; Woodliffe 1987; Austen et al. Acadian Flycatcher (Empidonax virescens). [accessed February 2009]. Federation of Ontario Naturalists, Don Mills, ON. However, unless a regulation is made earlier, habitat protection for this species will not be in place until June 2013. Results from the Atlas of the Breeding Birds of Ontario and the Acadian Flycatcher/Hooded Warbler Recovery Team indicate that the distribution has changed little since the 1990s.

Like other flycatchers, the species mainly forages in flight, catching flying insects such as bees, wasps, ants, beetles, and moths. The paucity of inter–year encounters of individuals banded as nestlings suggests that young generally disperse to other sites to breed (dispersal distance unknown). Carolinan Woodland Species at Risk (website). Is there an observed, inferred, or projected continuing decline in extent of occurrence? Despite improved protection available for woodlands in southern Ontario under the Planning Act and county tree–cutting bylaws, conversion and encroachment on forests for agriculture, rural residential developments, utility corridors, and urban sprawl is still occurring. 2008b. This report may be cited as follows: COSEWIC.

Polygyny rates in Ontario are variable (e.g., 7 of 29 males in 2002–03, 3 of 16 territorial males in 2007) and appear to be higher than elsewhere (e.g., 3 in 135 territories in Pennsylvania; Woolfenden and Stutchbury 2004a,b; Woolfenden et al. Cadman, M.D., P.F.J. The Acadian Flycatcher’s life cycle is fairly typical of other small passerines; most information below is summarized from Whitehead and Taylor (2002). Profile by Aidan Healey: The Acadian Flycatcher is a bird that experienced birders will often consider a challenge to identify. 2008. Pyle, P. 1997. However, such coarse–scale information again does not capture the Acadian Flycatcher’s specific habitat requirements. Although the population appears to have been relatively s over the past 10–20 years, this is most likely due to immigration from U.S. populations. Routes are not randomly situated. 1997.

In the southern portion of its range, the species is commonly found in large Bald Cypress swamps, but as it moves further north into the central and northern portion of its range, deciduous hardwood stands are more common habitats. In tableland settings, it nests in mature upland beech–maple woods and lowland soft maple swamps, often at the interface of wetland and upland knolls (Martin 2007; D. Sutherland pers. 2005). data). It is considered globally secure (G5) (NatureServe 2009). Birds of Nebraska - Online > Species > ACADIAN FLYCATCHER. Iverson, A. Prassad, T.S. They are olive-colored with white and sometimes yellowish side and belly areas, and usually have 2 white bars on their wings.

Également disponible en français sous le titre Évaluation et Rapport de situation du, Generation time (average age of parents in the population). Abundance data collected by general large–scale bird monitoring programs from the Canadian range are too sparse (only a few detections on BBS, FBMP and OBBA2 point counts) to be used to calculate a meaningful estimate of the Canadian population. Reproductive success of Acadian Flycatcher in the Blue Ridge Mountains of Virginia. Little is known about the migratory behaviour of this species (Whitehead and Taylor 2002). [accessed 25 October 2008]. In Ontario, this species is typically found either in large patches of mature deciduous forest or in mature, forested ravine settings, and has a demonstrated susceptibility to forest loss, fragmentation, and degradation.

This species is also presently listed as Endangered, Schedule 1 under the federal Species at Risk Act and the Ontario Endangered Species Act 2007. It breeds in eastern North America, and winters in Central America and northwestern South America (Figure 1). On a finer scale, habitat degradation has been observed at several Acadian Flycatcher sites due to heavy logging, the spread of invasive alien plants, and new house construction (Recovery Team data). 2000; Friesen et al. However, habitat shift for species associated with mature forests, such as the Acadian Flycatcher, is predicted to occur relatively slowly (at least one century), due to the lag time associated with tree migration and longevity (Matthews et al. Ontario Ministry of Natural Resources, ON. Pashley, C.J. 35 pp. In the meantime, they are available on request from the COSEWIC Secretariat. songs, or to fly out to catch insects. Information on the distribution of Acadian Flycatcher in Ontario benefited greatly from the efforts of numerous volunteers participating in the first and second Ontario Breeding Bird Atlas, the Ontario Rare Breeding Bird Program, and the Ontario Birds at Risk projects. Since 1997, many additional Acadian Flycatcher breeding locations have been identified, mostly as a result of directed searches coordinated by the Acadian Flycatcher/Hooded Warbler Recovery Team (see Sampling Effort for further details). 71 pp. Draft manuscript. Observed pairing success rates in Ontario are highly variable from year to year but are considerably lower (70% average at core sites) than observed in areas of higher population densities (91% average over 4 years in a Pennsylvania study area; Woolfenden et al.

Journal of Field Ornithology 80:234–241. However, it will take many decades before such habitat reaches sufficient maturity to support Acadian Flycatchers. The Acadian Flycatcher is protected under the federal Species at Risk Act (SARA). 2005). Bradstreet, G.S. Climate threats facing the Acadian Flycatcher. With small flycatchers, including this species, vocalizations are best for identification. PLEASE NOTE: Not all COSEWIC reports are currently available on the SARA Public Registry. The Acadian flycatcher breeds only in North America, primarily in the eastern half of the United States where the species is widespread and common. Least flycatcher (E. minimus) has lighter-colored undersides. It is listed as endangered by COSEWIC. A preliminary population and habitat viability analysis for the Acadian Flycatcher in Ontario suggested that the Canadian population is not self–sustainable and may become extirpated without a continuous influx from external populations (Tischendorf 2003). Summary Report, Contract # KW404–07–0824. songs, or to fly out to catch insects. Technical Series No. Of the dozen or more maddeningly similar species in the Empidonax genus, the cheery Acadian Flycatcher is the common one of mature forests of the Southeast and Mid-Atlantic U.S. Forest cover within the breeding range of this species in Ontario has not exhibited similar recovery trends to those in Northern New England over recent decades. COSEWIC assessed this species as Endangered in November 2000. 2006. BBS long–term trends for Ohio and Pennsylvania over the 1966–2007 period show declines of 2.3%/yr (p=0.04, n=53), and 0.4%/yr (p=0.28, n=78), respectively (Sauer et al.

The study predicted a 93% risk of extirpation after 100 years, given a starting population size of 30 breeding pairs and no immigration. It was considered a fairly regular but rare spring migrant at Prince Edward Point (Lake Ontario), with several records between 1976 and 1986 (Weir 1989); however, this species has not been reported there in recent years (Prince Edward Point Bird Observatory unpublished records 2001–2008). The effort–adjusted probability of observation for Acadian Flycatcher in Ontario increased significantly (by 86%) between the first (1980–85) and second (2001–2005) atlases (Cadman et al. However, the conclusions should be viewed as preliminary, because the study was based upon limited data and conservative estimates. 24–28 in Kettle, A. University of Waterloo Press, Waterloo, ON. website: [accessed February 2009]. However, a more recent meta–analysis of area and edge effects found that its occurrence is consistent with edge–avoidance and that it does not show significant patch–size effects (Parker et al. There is currently no evidence of spatial population structuring within the Canadian or North American population of this species. [accessed 25 October 2008]. Federation of Ontario Naturalists. 20. Quick Links: | Empidonax virescens. Rustay, J.M. Total survey effort in each of these coordinated surveys was similar, although there were differences in the sites covered.

This could also be an Alder or Willow Flycatcher. The most recent population estimate counted 20 to 30 pairs of birds. Acadian Flycatcher (Empidonax virescens) Status in Canada: Endangered. Outside of the breeding season, this species uses a broad range of habitats, but deforestation on the wintering grounds is a potential concern (Whitehead and Taylor 2002). 2009). There are also some summer records of territorial males at the Long Point and Big Creek National Wildlife Areas, but these are believed to have been unmated birds (J. McCracken pers. Bird–Banding 37:227–257. Acadian Flycatcher online maps (provisional data). Studies of Acadian Flycatcher occurrence and breeding success in the United States have shown that it is sensitive to site–, patch– and landscape–scale effects. Acadian Flycatcher (Empidonax virescens) in NatureServe Explorer: an online encyclopedia of life [web application]. Regardless, nests are nearly always suspended from the forks of lateral branches that extend more or less horizontally from the trunk; this particular growth form is a key feature of all the aforementioned species favoured by nesting Acadian Flycatchers (J. McCracken pers. These programs involved monitoring occupancy at known sites and searching areas of suitable habitat using a combination of knowledgeable volunteers and experienced contract staff.

The bird lives in the understory of woods with a closed canopy. Within a physiographic region, this species exhibits a high degree of habitat specificity at various scales (Bakerman and Rodewald 2006). Butcher, D. Demarest, R. Dettmers, E.H. Dunn, W. Easton, W.C. Hunter, E.E. Committee on the Status of Endangered Wildlife in Canada. The Acadian Flycatcher occurs within Long Point Wildlife Area, which is federal land protected under SARA. The Acadian Flycatcher is often used as a focal species for forest bird research in eastern North America because it is considered relatively easy to study, and is an indicator of forest habitat conditions at a range of scales. comm. Acadian Flycatcher in Ontario. Whitmore. Status historyDesignated Endangered in April 1994. Collectively, these threats to habitat greatly reduce potential for rescue from adjacent U.S. populations. About half of the known Acadian Flycatcher sites in Ontario are on publicly owned lands, but most of these sites are working forests that are being actively managed for timber and fuelwood production (Recovery Team unpubl. The species is threatened by forestry practices, particularly those that target removal of large trees. Journal of Field Ornithology 70:514–519. Online Version 6.3.2, Updated December 2008. This was followed by a trend of reoccupation of its former range starting in the 1960s, likely facilitated by maturation of second–growth forests in the northeastern United States (Whitehead and Taylor 2002). 1994. The 2002 southern Ontario Hooded Warbler/Acadian Flycatcher survey. The Acadian Flycatcher is a small migratory songbird. 2005. The Acadian Flycatcher has been known to migrate to Ontario for well over a century with the first nesting records dating back from 1884. Status at SWCR: Rare breeding bird. [Accessed September 2008]. Despite its similar appearance, the genetic signature of the Acadian Flycatcher is strongly differentiated from other Empidonax species and it is considered a separate single–species clade within this taxon (Zink and Johnson 1984; Johnson and Cicero 2002). Endangered and threatened species; Extinct species; Unaccepted species; News & updates; ACADIAN FLYCATCHER. 2006; Chapas–Vargas and Robinson 2006; Chapas–Vargas and Robinson 2007). 128 pp. 2003; Heagy and Badzinski 2008). This includes deciduous forests in the eastern United States west to Texas. It is also protected by the federal Migratory Birds Convention Act. 2009). It is often found in well-wooded swamps and ravines. However, the number of sites occupied in any given year has been fairly stable.

The Hooded Warbler is listed as Threatened nationally under the Species at Risk Act and Special Concern provincially under Ontario’s Endangered Species Act, 2007. Habitat within the existing forest patches is also degraded in that most forests in southern Ontario are exposed to logging that targets the removal of mature trees. The supply of mature, closed–canopy, open–understorey, interior–forest habitat is a limiting factor in many parts of its range, including southern Ontario. Nests with a cowbird chick rarely fledge any Acadian Flycatcher young (Whitehead and Taylor 2002). 2006; Rodewald and Shustack 2008). Population is generally secure across most of.

Although annual site occupancy is somewhat intermittent in Ontario owing to natural turnover of individuals, the species displays strong long–term attachment to particular sites, and routinely recolonizes them so long as they retain favourable breeding habitat. Ottawa. National Recovery Plan No. Acadian Flycatcher — Photo courtesy of Ron Ridout. Nevertheless, the survey data can be used to estimate the size of the Canadian population.In the 2007 surveys, 36 Acadian Flycatcher males were found at 25 sites in six counties/regions (Table 2); Heagy and Badzinski 2008). [accessed October 2008]. Available information suggests that the Acadian Flycatcher population in Canada has been relatively stable over the past decade, and stable or increasing modestly over the past few decades. Several core breeding locations have been monitored more frequently, with more intensive studies involving nest monitoring, colour banding, and territory mapping projects carried out in some years (Martin 2001, 2005; Woolfenden and Stutchbury 2004a,b; P. Burke 2006, 2007). Alan Dextrase, Ontario Ministry of Natural Resources, Peterborough, Ontario. In addition to the distinctive peet–sa territorial song, males and females have other characteristic vocalizations that can provide clues as to breeding status and nest locations. 1994).

The female typically lays 3 eggs in a cup nest suspended from the outer branches of a tree, at a height of 3 to 9 m. Pairs will usually re–nest if a nest fails and will sometimes nest again after having a successful nest. Nests in Ontario and elsewhere are situated 3 to 9 m high in small trees, saplings and shrubs (Friesen et al. Breeding season records from northern New England since the 1980s indicate an expansion of the historic breeding range in the northeastern United States (Whitehead and Taylor 2002). The incubation period is about 14 days; incubation and brooding is by the female only. The Committee meets to consider status reports on candidate species. COSEWIC History of Status Designation: Designated Endangered in April 1994. The Canadian breeding range of the Acadian Flycatcher is largely restricted to the Carolinian Region of southern Ontario. Acadian Flycatcher: Empidonax virescens: Least Concern (LC) Black Phoebe: Sayornis nigricans: Least Concern (LC) Long-tailed Tyrant: Colonia colonus: Least Concern (LC) Bright-rumped Attila : Attila spadiceus: Least Concern (LC) Choco Sirystes: Sirystes albogriseus: Least Concern (LC) Rufous Mourner: Rhytipterna holerythra: Least Concern (LC) Dusky-capped Flycatcher: Myiarchus … Adults have olive upperparts, darker on the wings and tail, with whitish underparts; they have a white eye ring, white wing bars and a wide bill. Ontario Ministry of Natural Resources. 256–257 in M.D. Yellow-bellied Flycatcher Empidonax flaviventris Doug Gross/PGC Photo . The 1998 data suggest that there are still between 35 and 50 pairs in Canada. vii + 12 pp. records 2006–07). Birds of the Kingston Region. There is no information on its distribution in Ontario prior to the late 1800s, by which time the landscape of southern Ontario had been radically altered by the conversion of the extensive woodlands and wetlands to agricultural cropland and pasture (Austen et al. Beck, D. Lepage, and A.R. Regional forest cover is below the 30% minimum guideline for sustaining forest bird biodiversity (Environment Canada 2004) in all parts of the Carolinian region, and is less than 5% in some parts of the region. The FBMP is a volunteer–based program designed to complement the BBS. Stutchbury. Gipson. Couturier (eds). Dave Martin, Environmental Consultant; Belmont, Ontario. Atlas of climate change effects in 150 bird species of the Eastern United States (PDF, 651 KB). The Acadian Flycatcher was flagged as a rare species and atlassers were asked to provide detailed documentation. It is found in the southeastern regions of North America. Acadian Flycatcher, pp. 11 pp. comm. call / song. The Acadian Flycatcher may also be relatively tolerant of predicted climate changes, because it is generally adapted to a warmer climate. Males attract females with their unique song and erratic courtship displays, and establish nesting territories. Partners in Flight. In Ontario, eggs are laid between June 8 and July 30. Update COSEWIC status report on the Acadian Flycatcher Empidonax virescens in Canada, in COSEWIC assessment and status report on the Acadian Flycatcher Empidonax virescens in Canada. However, the response to these factors is not always consistent across the breeding range, possibly because these site and edge effects can be masked by the impact of more pervasive landscape–level effects (Robinson and Robinson 1999; Bell and Whitmore 2000; Hazler et al. November 2008. Nest predation is the most common cause of nest failure. The 95 nesting attempts tracked in Ontario for the 2001–2004 period fledged an average of 1.7 young per female per year (Table 1). 2000. Most of the increase in forest cover in southern Ontario over the 20th century was in the Lake Simcoe – Rideau region. The forests within the Canadian breeding range of this species are highly fragmented, with two–thirds of all forest patches being less than 5 ha, and with only 431 patches being over 100 ha in size (Flaxman 2004). Conservation Biology 13:58–66. The current extent of occurrence (EO) of the Acadian Flycatcher in Canada, as delineated by the range envelope polygon described by occurrences reported during the 2001–2005 Atlas project (Figure 2), is approximately 36,500 km². Mulvihill. The Acadian Flycatcher is protected in Canada under the Migratory Birds Convention Act (MBCA 1994). 2008; Rodewald and Shustack 2008; Rodewald 2009). Feather and blood samples collected in 2003 from Acadian Flycatchers breeding in Canada and the Great Lakes states have not yet been analyzed (Woolfenden and Stutchbury 2003; Stutchbury, pers. Evolutionary genetics of flycatchers: sibling species in the genera Empidonax and Contopus. This species is ranked as Least Concern on the IUCN Red List by BirdLife International (BLI) and as Globally Secure (G5) by NatureServe (BLI 2004; NatureServe 2008). From the southern areas of New Hampshire, west through Maine, through New York to the southern boundaries of the Great Lakes. Clements, J.E. 15 pp.plus appendices.

Audrey Heagy is a Bird Conservation Planning Biologist with Bird Studies Canada, a non–profit, non–governmental bird research organization with headquarters in Port Rowan, Ontario. Rosenberg, A.O. NatureServe, Arlington, Virginia. ), it is illegal to take, transport, possess, process, or sell any wild animal on the Wisconsin Endangered and Threatened Species List (ch. plus appendices. . As with other small passerines, the expected life span is short, and the generation time (average age of breeding adults) is likely 2–3 years. Fauth, P.T. Although the population appears to have been relatively stable over the past 10-20 years, this is most likely due to immigration from U.S. populations. Lambert, L.R. comm. However, given the consistency of past survey results, it seems probable that about half of all occupied sites were included in the 2007 surveys. The Acadian Flycatcher is listed as Endangered federally and appears on Schedule 1 of the Species at Risk Act. Almost all atlas squares (10 x 10 km) in the Carolinian and Lake Simcoe–Rideau atlas regions in southern Ontario received some coverage in both atlases and most received more than 20 hours of coverage. Its ability to use different nest trees may be important because some of the preferred nest tree species (e.g., hemlock and beech) are being decimated by invasive forest pests (Hemlock Wooly Adelgid, Adelges tsugae, and beech bark disease, Nectria gallingea) in the northeastern United States, and similar tree mortality is expected to occur in southern Ontario within the next decade.
