Now, researchers at the University of Missouri, Columbia, have found that the Acadian flycatcher
is at risk of severe population decline--across the 96,000,000-acre Central Hardwoods Region--within the century if the climate continues to warm.
We monitored 997 active nests of eight species with sufficient sample sizes to fit nest survival models including 73 Acadian flycatcher
(Empidonax virescens, [n.sub.eff] = 1276), 172 bluegray gnatcatcher (Polioptila caerulea, [n.sub.eff] = 1980), 256 Eastern wood-pewee (Contofms virens, [n.sub.eff] = 5344), 72 field sparrow (Spizella pusilla, [n.sub.eff] = 608), 207 indigo bunting (Passerina cyanea, [n.sub.eff] = 2206), 47 prairie warbler (Setophaga discolor, [n.sub.eff] = 504), 66 summer tanager (Piranga rubra, [n.sub.eff] = 893), and 102 yellow-breasted chat (Icteria virens, [n.sub.eff] = 1021) nests.
Based on logistic regression, there were positive correlations between buffer width and presence of Wood Thrush and Acadian Flycatcher
(Empidonax virescens) (P = 0.048, P = 0.045, respectively).
The sighting of an Acadian flycatcher
- a small creature normally found in America - prompted birdwatchers to travel to Dungeness in Kent from across the country.
More than 1,000 birdwatchers landed by the sea in their bid to glimpse an acadian flycatcher
As a foundation species, hemlocks provide habitat for a host of other species: unique mixes of salamanders, fishes and birds, such as the black-throated green warbler and Acadian flycatcher
. They also shelter deer, porcupines and other animals, especially in winter.
At the banding station, visitors can marvel at the intense orange of a Baltimore oriole or the "whiskers" on an Acadian flycatcher
. Our banders release their charges unharmed.
In addition, Bohm Woods is also distinguished by supporting higher numbers of forest interior species, including two Neotropical migrants sensitive to fragmentation, Acadian Flycatcher
and Wood Thrush (Roth et al., 1996; Whitehead and Taylor, 2002; Table 6).
Each selected bird is a relatively rare and difficult to find specimen of birdlife ranging from the Surf Scoter, to the Whooping Crane, to the Acadian Flycatcher
, to the Evening Grosbeck.
Bird species such as the American robin (Turdus migratorius), Bachman's sparrow (Aimophila aestivalis), common yellowthroat (Geothlypis trichas), Eastern bluebird (Sialia sialis), and Northern bobwhite (Colinus virginianus) were detected only in treated stands, while Acadian flycatcher
(Empidonax virescens), wood thrush (Hylocichla mustelina), yellow-billed cuckoo (Coccyzus americanus), and yellow-throated vireo (Vireo flavifrons) were detected only in untreated stands.
One guide to North American birds describes the song of the Acadian flycatcher
as "an explosive peet-suh" (perhaps topped with hearts of napalm).
Several eastern species, including the wood thrush, Acadian flycatcher
, and Kentucky warbler, breed in the forested areas of the Piney Woods of East Texas, while Swainson's warblers and swallow-tailed kites can be seen in the swampy stream bottoms.
