2008), the overall Acadian Flycatcher population in North America appears to be reasonably well monitored by the BBS (detected on 973 routes situated throughout the US breeding range). Wilson Bulletin 112:524–531. The Acadian Flycatcher or Green-crested Flycatcher, Empidonax virescens, is a small insect-eating bird of the tyrant flycatcher family. The supply of mature, closed–canopy, open–understorey, interior–forest habitat is a limiting factor in many parts of its range, including southern Ontario. 2000. The Acadian Flycatcher’s life cycle is fairly typical of other small passerines; most information below is summarized from Whitehead and Taylor (2002). Acadian flycatchers look very similar to closely related birds like alder flycatchers, yellow-belied flycatchers, willow flycatchers, and least flycatchers. 4 pp. Cadman, P.F.J. 1994. 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. The Willow Flycatcher is endangered because of its loss of habitat due to cowbird parasitism and its competition with the Alder Flycatcher. However, the number of sites occupied in any given year has been fairly stable. National Recovery Plan No. Longevity records for Acadian Flycatcher and White–eyed Vireo following prescribed timber harvest. The Acadian Flycatcher is protected in Canada under the Migratory Birds Convention Act (MBCA 1994). Eagles, and F.M. 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. Population size is <2500 mature individuals but there is no evidence for decline or extreme fluctuation in numbers. Brown-crested flycatcher. Heagy, A., D. Martin, and J. McCracken. (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. No estimates of lifetime reproductive success are available (Whitehead and Taylor 2002). It is often found in well-wooded swamps and ravines. If correct, these figures suggest that roughly half of the potential Acadian Flycatcher habitat in southern Ontario has not been surveyed. The Acadian Flycatcher was flagged as a rare species and atlassers were asked to provide detailed documentation. Yellow-bellied Flycatcher Empidonax flaviventris Doug Gross/PGC Photo . Endangered Species Act, 2007. Scientific name:  Empidonax virescensEnglish name:  Acadian FlycatcherFrench name:  Moucherolle vert. Nests in Ontario and elsewhere are situated 3 to 9 m high in small trees, saplings and shrubs (Friesen et al. Quick Links: | 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.

Unpublished Report for Environment Canada, Interdepartmental Recovery Fund Project # 31, FY 2002–03. Shustack. Hoover, J.P., T.H. Population viability is further compromised by reduced seasonal reproductive output, most likely due to reduced habitat quality (e.g., fragmentation, proximity to forest edge) that leads to elevated rates of nest predation and brood parasitism. 2005). 688 pp. Recovery Team | Dusky-capped flycatcher. Several municipalities have designated significant wildlife habitat, significant woodlands and valley lands in their Official Plans. 2006 Acadian Flycatcher field work data summary. Acadian flycatchers also occupy dry woods but they usually prefer to hang their nests over water. Deschamps, V. and J.D. Sutherland, G.G. Diameter-limit tree harvest is a common silviculture practice where the oldest and largest trees are harvested, drastically reducing the canopy cover.

Estimated Canadian population (individuals): 110 . Using average pairing success (70%) and polygyny (20%) rates for the Ontario population (see Life Cycle and Reproduction), the 2007 count is estimated to consist of approximately 10 unmated territorial males, 18 monogamous pairs, and 4 polygynous groups (each consisting of one male and two females), for a total count of about 56 adults (32 territorial males and 24 paired females). Report for Recovery Team Meeting. Criterion D (Very Small Population or Restricted Distribution): Meets Endangered D1; population size (60–180 adults) is <250 mature individuals. 1987. 1998. Habitat area requirements of breeding forest birds of the Middle Atlantic states. Verbal communication with A. Heagy. It favours species of nest trees that have a particular growth form. 2004. However, many areas of potentially suitable habitat on private lands in the Carolinian region have never been searched. Species designated at meetings of the full committee are added to the list. Dark wings with distinct white wingbars. Bell, J.L., and R.C. Because Acadian Flycatchers most commonly nest in large blocks of mature, closed-canopy forest habitats, they are sensitive to forest fragmentation effects. Status historyDesignated Endangered in April 1994. 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. Acadian FlycatcherThe Acadian flycatcher is a small flycatcher. The Canadian Wildlife Service, Environment Canada, provides full administrative and financial support to the COSEWIC Secretariat. en Two additional Carolinian bird species were newly listed in 1994, the endangered Acadian Flycatcher and the threatened Hooded Warbler. Acadian Flycatcher habitat selection in south–western Ontario. This species is also part of a suite of Neotropical migrant forest songbirds that has been the subject of extensive studies in the northeastern United States and southeastern Canada in connection with the impact of silvicultural practices, and landscape–, patch– and site–scale forest metrics on reproductive success and population dynamics (Whitehead and Taylor 2002; Woolfenden et al. 334–345 In Cadman, M.D., D.A. In size, it is slightly larger than a house sparrow, and in appearance it is similar to other flycatchers of the genus Empidonax. Atlas of the Breeding Birds of Ontario, 2001–2005. Description | BBS data have been used to calculate population estimates and population trends at various geographic scales (Rich et al. Rodewald, A.D. 2009. Is the total population severely fragmented? Most sites surveyed received only one visit, but follow–up visits were made to most sites where Acadian Flycatchers were detected on the first visit. Owing to the turnover of small numbers of site–faithful adults, sites containing suitable habitat may be occupied by one or more pairs for several consecutive years, then fall unoccupied for a short period, only to be re–colonized again a few years later. Recolonization of sites is common, provided that habitat remains suitable. The Ohio study covered a rural–urban gradient and found that productivity was significantly lower in more urbanized areas (Rodewald and Shustack 2008; Rodewald 2009). Relatively little is known about the biology of this species on migration or on its wintering grounds (Whitehead and Taylor 2002). The nearest core breeding population, in the heavily forested central Appalachian Mountains, is about 250 km from the Canadian population. Total field effort in these regions increased moderately during OBBA2. 2005. As of October 2015 there have been 2 records of Acadian flycatcher in Europe, the first being a bird found dead in Iceland in 1967, and the second a bird found on the beach at Dungeness in Kent, England in September 2015, the latter's identity being established by DNA from its droppings.

What is NCC doing to conserve habitat for this species? 262 pp. Gauthier, J. and Y. Aubry (eds). Marked year–to–year differences in pairing success suggest that the sex ratio of these influxes is skewed towards males, which is consistent with the observed differential timing of spring migration by sex. In ravine and riparian settings in Ontario and the northeastern U.S., this species shows a strong preference for sites with an Eastern Hemlock (Tsuga canadensis) component (Martin 2007; Becker et al. 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 invasive forest insects and pathogens. Is there an observed continuing decline in number of mature individuals? 1999. Update COSEWIC Status Report on the Acadian Flycatcher Empidonax virescens in Canada. The paucity of inter–year encounters of individuals banded as nestlings suggests that young generally disperse to other sites to breed (dispersal distance unknown). Blancher, P.J., K.V.

Data on population change prior to the 1980s are scarce. Available information on the Canadian population gleaned from Recovery Team reports and databases is summarized in this section, supplemented with relevant information from studies in the U.S. Annual re–use of particular breeding sites in Ontario is often intermittent or sporadic; hence,“traditional” Acadian Flycatcher sites here show a pattern of intermittent occupancy (Martin 2007; Recovery Team unpubl. 2000. This includes deciduous forests in the eastern United States west to Texas. Journal of Wildlife Management 70:532–538. In the hand, this species can be distinguished from other Empidonax sspecies by a combination of features including size (wing chord 65–80 mm), bill shape and colour, grey legs, and an especially long primary projection (Pyle 1997). Kennedy, A. Martell, A. Panjabi, D.N. 2008. The Acadian Flycatcher may also be relatively tolerant of predicted climate changes, because it is generally adapted to a warmer climate. Iverson, and A.M.

KW405–05–0215, Species at Risk Recovery Program, Environment Canada. This species also receives legal protection in the United States and Mexico under similar legislation. Plumages of both sexes are similar but males are significantly larger than females and the combination of wing chord and tail length measurements can be used to discriminate between the sexes (Wilson 1999). Catalogue CW69-14/5-2010E-PDF ISBN 978-1-100-15955-3 Recycled paper. 2007). The Acadian flycatcher breeds only in North America, primarily in the eastern half of the United States where the species is widespread and common. The Acadian Flycatcher is also listed as Endangered under Ontario’s Endangered Species Act, 2007 (ESA; Ontario Ministry of Natural Resources 2008a, b). Robinson, W.D. 35 pp. 2006. Website: [accessed October 2008]. 2007. In upland situations, it largely avoids forest edges and is therefore rarely found in small isolated forest fragments. Snell, and H.G. 2008. The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) was created in 1977 as a result of a recommendation at the Federal–Provincial Wildlife Conference held in 1976. Climate change could potentially expand the bioclimatic limit of this species to include areas of extensive woodlands in the Southern Shield region of southern Ontario (Martin 2007). 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. This engaging little Acadian Flycatcher loves moist streamsides, and bottomland hardwood forest and is the most abundant of the Empidonax flycatchers found in Tennessee.. 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. Territorial males sing frequently throughout the breeding season; females also sing on occasion (Whitehead and Taylor 2002). The lower figure is comparable to the 12 of 135 territories held by single males in a Pennsylvania study (Woofenden et al. Long–term changes in the extent and distribution of woodlands in southern Ontario have been described by Larson et al. [accessed 27 October 2008]. Dispersal rates are not sufficient to prevent site turnover, but appear to be sufficient to maintain the overall Canadian population. Rare casual … Hooded Warblers are a nationally threatened species, with just 150 to 210 nesting pairs found each year. Threatened. McFarland, J.D. 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. 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. Chapas–Vargas, L. and S.K.

The North American Breeding Bird Survey, Results and Analysis 1966–2007. 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. 2000; Bakerman and Rodewald 2006; Chapas–Vargas and Robinson 2007). Acadian Flycatcher. Report for Environment Canada, National Wildlife Research Centre. In tableland forests, nests are often situated over vernal pools, trails or patches with little or no ground cover. 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. Estimated percent of continuing decline in total number of. The Woodland Heritage of Southern Ontario: A study of ecological change, distribution, and significance. Fluctuations in the numbers reported on spring migration in Ontario also indicate that periodic influxes of birds (presumably overshoots from the United States) occur in some years, presumably prompted by certain weather conditions that occur during migration. Ralph, T.D. Natural Heritage Information Center (NHIC). Wings are olive-gray with two buff wing bars. Consequently, Acadian Flycatcher breeding habitat is also vitally important to many other Canadian species at risk. 1998; Carson et al. Woolfenden, B.E., B.M. 2002. Males and females look alike. Several of the Acadian Flycatcher’s preferred nest tree species (hemlock, beech, flowering dogwood) are being decimated by invasive forest pests and pathogens (Hemlock Wooly Adelgid, beech bark disease, and dogwood anthracnose) in the northeastern United States. Cornell Lab of Ornithology, Ithaca, NY. 2003. 986 pp. 2006; Becker et al. Nearby areas with a more open canopy and higher regeneration cover are important during the critical post–fledging period (Burke 2007a). This assumes that potential habitat is evenly distributed throughout the EO, which is probably not the case, because private lands are generally exposed to higher intensities of forest management than public lands. 2008a. Planning decisions requiring municipal approval must be consistent with the PPS. Conservation Biology 13:58–66. References There is currently no evidence of spatial population structuring within the Canadian or North American population of this species. The Acadian Flycatcher winters in a range of lowland and pre–montane forest habitats in Central and South America, including the understorey of humid forest, second–growth woodlands, forest edges, and shrub thickets (Whitehead and Taylor 2002; NatureServe 2008).

It is considered globally secure (G5) (NatureServe 2009). Once critical habitat is identified under SARA, only those portions present on federal lands will be protected. It also is listed as Endangered provincially and is protected under Ontario’s Endangered Species Act, 2007. In ravine settings, nests are located near (often over) a stream. One analysis from Ohio reported apparent annual survival of males of 0.53 ± 0.056 SE, versus females of 0.23 ± 0.064 SE (Rodewald and Shustack 2008).

Preliminary coarse–scale habitat modelling exercises based on landcover data suggested that the amount of potential habitat for Acadian Flycatchers in southern Ontario may be as much as two orders of magnitude greater than the present area of occupancy (Flaxman 2004). In ravine situations, however, territories can be linear and the species appears to be less sensitive to edge effects. Only small numbers breed in Canada. Criterion E (Quantitative Analysis):Preliminary analysis suggests that persistence of the Canadian population relies on regular immigration of at least small numbers of breeding adults from the adjacent states.

Rodewald, A.D. and D.P. 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.

Due to ease of access and proximity to known sites, survey effort has been concentrated in the extensive public forests in Norfolk County, wooded ravines in Elgin County, and public lands within a few large forest complexes elsewhere in the Carolinian region. However, unless a regulation is made earlier, habitat protection for this species will not be in place until June 2013. 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.

Immigration of individuals from the United States may be essential to maintaining the overall Canadian population (Tischendorff 2003; Martin 2007), provided that suitable habitat is retained here. 5. 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). Empidonax virescens (Acadian Flycatcher) is a species of birds in the family tyrant flycatchers. Acadian Flycatcher nests are parasitized by the Brown–headed Cowbird (Molothrus ater). The species at risk act (SARA) prescribes identification and protection of critical habitat for this species. 1991. General Technical Report NE–318. 1997; McCracken et al. The Ontario ESAprotects listed species from harm. 2007. 2008. Ottawa. Environment Canada, Canadian Wildlife Service, Ottawa, ON. Collectively, these threats to habitat greatly reduce potential for rescue from adjacent U.S. populations. The explosive peet-sah, and its high-pitched twitter as it flies from perch to perch, are both distinctive. 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.
