Best distinguished from other flycatchers by habitat and voice. McCracken et al. Volume II. Acadian flycatchers don't have any known negative economic impact on humans. Productivity may not be sufficient to maintain the Canadian population, and its survival here may be quite dependent on immigration from the large Acadian Flycatcher population in the United States, particularly from Great Lake states bordering southern Ontario. Is there sufficient habitat for immigrants in Canada? Males and females appear similar, and both have greenish-olive heads and upperparts … 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. All Acadian Flycatchers breeding in Canada are within a single geographic region. This estimate is consistent with previous population estimates (Table 3). The Acadian Flycatcher has been characterized as an area–sensitive species (e.g., Robbins et al. The weather wasn’t massively impressive and the first two or three hours of the day passed by with little of note on the cards. 0:00 / Acadian flycatcher (call / song) call, song.

Deschamps, V. and J.D. 2005). Infestations are currently only about 200 km from Ontario. Criterion A (Decline in Total Number of Mature Individuals): Does not meet criterion. However, the conclusions should be viewed as preliminary, because the study was based upon limited data and conservative estimates. The Acadian Flycatcher or Green-crested Flycatcher, Empidonax virescens, is a small insect-eating bird of the tyrant flycatcher family. Virtually no forested areas in the Carolinian region are more than 600 m from the nearest edge, which was found to be the effective extent of forest–edge sink habitat in a study in moderately fragmented forest in Illinois (Hoover et al.

At Long Point, it is an irregular rare spring migrant, with a maximum of 8 individuals banded in a year (Long Point Bird Observatory unpubl. Single–day occurrences of single birds observed in suitable habitat (and sometimes unsuitable habitat) in June are generally considered to be late migrants or wandering non–breeders. November 2008.

Repeat surveys of known Acadian Flycatcher sites indicate that over the past decade, habitat degradation is more pervasive and a more significant threat than outright loss of forest habitat, especially in tableland settings. 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. 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). 1989. 1998; Carson et al. Stats. 1994; Larson et al. 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). In Ontario, many June records of single singing males present in suitable (or marginal) habitat for one or a few days appear to be late migrants or wandering individuals that have overshot or not yet reached their breeding grounds. Verbal communication with A. Heagy. This rate is similar to the annual reproductive productivity of about 1.6 fledged young per pair (n=193, range 0 to 7 young per pair per season) over a 6–year study in Ohio but about half the seasonal fecundity rate of 1.8 female fledglings per adult female (n=30) per season reported in a study in an extensively forested area in Virginia (Fauth and Cabe 2005; Rodewald and Shustack 2008). In the 1980s, several new breeding locations were discovered scattered throughout the Carolinian region, likely the result of increased coverage during the first breeding bird atlas (Speirs 1985; Woodliffe 1987; James 1991; Austen et al.

Final report to Environment Canada. Parker, T.H., B.M. Although deforestation of the wintering grounds is a potential concern, there is no strong evidence that habitat loss there is affecting Canadian or North American breeding populations of Acadian Flycatchers. Documents. No estimates available for the other 19 squares. Breeding distribution of the Acadian Flycatcher in Ontario, showing overall extent of occurrence (adapted from Cadman et al. The Acadian Flycatcher was designated as "Endangered" Species in 2000 by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). In tableland situations, the threats posed by beech bark disease and dogwood anthracnose are equally severe. Partners in Flight (PIF) Population Estimate Database. 2000; Bakerman and Rodewald 2006; Chapas–Vargas and Robinson 2007). The Acadian Flycatcher has been known to migrate to Ontario for well over a century with the first nesting records dating back from 1884. SARA establishes COSEWIC as an advisory body ensuring that species will continue to be assessed under a rigorous and independent scientific process. However, unless a regulation is made earlier, habitat protection for this species will not be in place until June 2013. Atlas of the Breeding Birds of Ontario, 2001–2005. Robinson. The PPSalso provides some protection to forests, including enabling municipal tree–cutting bylaws, and providing protection for designated significant woodlands and valley lands. It lives in mature, canopied forests. Acadian FlycatcherThe Acadian flycatcher is a small flycatcher. Strong site fidelity has also been reported on the wintering grounds (Whitehead and Taylor 2002). 2008.

Interim Report for Recovery Team Meeting, 2 November 2004. 334–345 In Cadman, M.D., D.A. Cadman, P.F.J. In Canada, the Acadian Flycatcher occurs in very low numbers in the Carolinian area of southern Ontario. Acadian Flycatchers have not been confirmed breeding on federal lands in Ontario. 1994. The home range of breeding males is therefore considerably larger than the territory size. call / song. 2000. The low point for forest cover in southern Ontario occurred around 1920 at about 11% (Larson et al. Rich, T.D., C.J. It is also protected by the federal Migratory Birds Convention Act. Yellow-bellied Flycatcher Empidonax flaviventris Doug Gross/PGC Photo . WorldCat Home About WorldCat Help. 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. Bisson, I.A., D. Martin, and B.J.M. Panjabi, B. Altman, J. Bart, C.J. 2004). Bird Studies Canada, Environment Canada, Ontario Field Ornithologists, Ontario Ministry of Natural Resources, and Ontario Nature, Toronto. Highly endangered species! Forest cover in all parts of the Carolinian region remains well below the 30% threshold considered necessary to maintain forest bird diversity (OMNR 2000; Environment Canada 2004). 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. The Acadian Flycatcher is identified as one of 195 species of Continental Importance in the North American Landbird Conservation Plan because 98% of its global population breeds within the Eastern Avifaunal Biome, and agencies in that avifaunal region have a high stewardship responsibility for the conservation of this species (Rich et al. The upper part of the bill is dark; the lower part is yellowish. 2007; PIF 2008; Sauer et al. COSEWIC status report on the Acadian Flycatcher Empidonax virescens in Canada. Regular surveys since 1997 indicate that the population in southern Ontario has been relatively stable, although there has been considerable variation in which sites are occupied or have multiple pairs. Brown, P.A. Ottawa. Conserving what’s left of southern Ontario’s forest birds. 4 pp. Conservation genetics of the Acadian Flycatchers–an interim report. Pennsylvania Breeding Bird Atlas (BBA). 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. It is an insectivore. Although there is no quantitative estimate of the relative amount of suitable habitat available in ravine versus tableland settings in southern Ontario, it appears that ravine settings are favoured by Acadian Flycatchers here, perhaps because these sites are less likely to be exposed to intensive logging practices and hence have relatively undisturbed older–growth features. An estimated 52,000 birds (1.1% of the global population) breed in the fragmented forests of the Lower Great Lakes/St. Perhaps equally important are logging practices in the remaining forests that are incompatible with maintaining the species. Conservation The populations nationwide appear to be stable, but may be declining in the Midwest. Given that search effort on private lands is limited and that a few new sites are being found every year, it is clear that a number of birds are being missed during these periodic surveys. (1998) suggested that the Ontario breeding population exhibits considerable year–to–year population fluctuations. Male Acadian Flycatchers, Empidonax virescens, obtain extra–pair fertilizations with distant females. Acadian Flycatcher, Dungeness, Kent, (© Martin Casemore) September 22nd wasn’t really the most auspicious of days on paper. Unpublished report for the Acadian Flycatcher & Hooded Warbler Recovery Team. Allen Woodliffe, Ontario Ministry of Natural Resources, Chatham, Ontario. 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). Brown–headed Cowbirds will occasionally lay eggs in Acadian Flycatcher nests and these parasitized nests rarely produce any young flycatchers. However, the number of sites occupied in any given year has been fairly stable. In 1978, COSEWIC designated its first species and produced its first list of Canadian species at risk. Cadman.

Becker, and P.S. songs, or to fly out to catch insects. Due to a large, stable population, the Acadian Flycatcher has … 2005). 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. The index of area of occupancy (IAO) is estimated to be ≤200 km² if a maximum of 50 sites is assumed to be occupied in any given year, and based on a 2 x 2 km grid overlay. 1999. 1987; Cadman et al. The paucity of inter–year encounters of individuals banded as nestlings suggests that young generally disperse to other sites to breed (dispersal distance unknown). Education. 1985. 2000. Report for Recovery Team Meeting. Remaining forest habitat mostly consists of small, isolated, and highly fragmented patches, with only a few hundred patches over 100 ha and little interior area more than 200 m from a forest edge. The Canadian distribution of this species was mapped by the first and second Ontario Breeding Birds Atlas (OBBA1 and OBBA2) projects, carried out between 1981–85 and 2001–05, respectively (Cadman et al. Wildlife species assessed by COSEWIC as Extirpated, Endangered, Threatened or Special Concern will be considered for legal protection and recovery (or management) under the Species at Risk Act (SARA). Wings are olive-gray with two buff wing bars. In the United States, the species is nationally secure (N5B) (NatureServe 2009) and occurs in 33 states with varying sub-national ranks 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. Widespread habitat loss threatens the species and has raised conservation concerns. [Annette M Page; Michael D Cadman; Committee on the Status of Endangered Wildlife in Canada.] Empidonax virescens (Acadian Flycatcher) is a species of birds in the family tyrant flycatchers.

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. Report for Environment Canada’s Habitat Stewardship Program. Invasive species and pathogens are of concern in breeding habitat. Only small numbers breed in Canada. 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. Woolfenden, B. and B. Stutchbury. Acadian Flycatchers are habitat specialists, nesting in mature closed- canopy forests with an open understorey. Recovery Initiatives | These counts cannot be directly converted into number of breeding pairs or adults. Are there extreme fluctuations in number of locations? Mean clutch size for Acadian Flycatcher nests in Ontario is 2.9 ± 0.4 (range 1–4, n=104), which is similar to elsewhere (ONRS 2008). Sutherland, G.G. 1999. 2008. Annotated Checklist of the Birds of Ontario, Second Edition. 159 pp. Habitat loss and degradation are the biggest threats to Acadian Flycatchers. Success rates from as low as 10 to 25%, to as high as 65% have been reported in U.S. studies (Whitehead and Taylor 2002). 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. data). They are olive-colored with white and sometimes yellowish side and belly areas, and usually have 2 white bars on their wings. Godfrey, W.E. Locally uncommon regular breeder southeast, accidental northeast. Is there an observed, inferred, or projected continuing decline. 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. Total survey effort in each of these coordinated surveys was similar, although there were differences in the sites covered. 395 pp. Threatened. She has more than 10 years’ work experience focusing on birds at risk, breeding bird surveys, bird banding, migration monitoring, and landbird conservation in Ontario. Bird nesting ecology in a forest defoliated by gypsy moths. NR 27, Wis. Admin. On June 5, 2003, the Species at Risk Act (SARA) was proclaimed. 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. Any further fragmentation or conversion of forest habitat in the Carolinian region is of particular concern, given the current conditions (low regional forest cover and high fragmentation). Urban–associated habitat alteration promotes brood parasitism of Acadian Flycatchers. Status re-examined and confirmed in November 2000 and April 2010. BirdLife International. If correct, these figures suggest that roughly half of the potential Acadian Flycatcher habitat in southern Ontario has not been surveyed. The higher figure is based on the number of singing males reported during extensive surveys (e.g., 19 of 36 males in the 2007 survey), which include males that were found only on a single visit. The Second Atlas of Breeding Birds for New York State. Most Canadian breeding records fall within the Carolinian biogeographic region, which is generally equivalent to the provincial Lake Erie–Lake Ontario and the federal Lake Erie Lowland ecoregions. [accessed 25 October 2008]. Pyle, P. 1997. Black phoebe. It winters in Central America and northern South America from Nicaragua to Ecuador and Venezuela. Clements, J.E. 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. The productivity of the population in southern Ontario is adversely affected by degraded habitat conditions, particularly low regional forest cover and high forest fragmentation. 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. Committee on the Status of Endangered Wildlife in Canada, Ottawa, ON. Population is generally secure across most of. Across the breeding range, there are geographic differences in the specific habitats selected and in its response to landscape characteristics. Cadman, and R.D. Strategic habitat restoration efforts are underway to enhance forest–interior habitat in several of the core forest complexes in the Carolinian region, and to re–forest riparian corridors generally in southern Ontario. NatureServe, Arlington, Virginia. Long Point Bird Observatory, Port Rowan, ON. Committee on the Status of Endangered Wildlife in Canada. The Acadian flycatcher requires large areas of mature undisturbed forest. Its range extends north to the Great Lakes and southern New England, and it has been gradually expanding this range toward the north. comm. By 1986, total forest cover in southern Ontario had increased to about 19%, but most of this consisted of second–growth replacement forests and the extent of original forest had declined to only 5.8% of total land cover (Larson et al. The Species at Risk in Ontario (SARO) List, 30 June 2008. In the absence of comparable quantitative data sets, recent trends in the amount of forest and interior forest within the Canadian breeding range of the Acadian Flycatcher are difficult to assess.

Acadian Flycatcher (Empidonax virescens) Range: NA info. 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). In tableland forests, nests are often situated over vernal pools, trails or patches with little or no ground cover. Ash-throated flycatcher. Twedt, D. 2008. Digital Distribution Maps of the Birds of the Western Hemisphere, version 3.0. In Ontario and elsewhere, it is found primarily in deciduous and mixed forests (Whitehead and Taylor 2002; Martin 2007).
