Bird species of special concern which appeared in the 2005 survey or other surveys are<br />
summarized below.<br />
Olive-sided flycatcher<br />
The olive-sided flycatcher is considered a special status species in the Study Area. The<br />
flycatcher is primarily found in coniferous forest biomes throughout North America, but is<br />
occasionally found in mixed deciduous/coniferous forests. The olive-sided flycatcher is<br />
associated with openings, including muskegs, meadows, disturbed burned <strong>and</strong> logged areas,<br />
streams, beaver ponds, bogs, <strong>and</strong> lakes. The olive-sided flycatcher is recognized by USFWS<br />
as a National Species of Management Concern (USFWS 1995) <strong>and</strong> by ADF&G as a species<br />
of special concern (ADF&G 2005c). The olive-sided flycatcher is listed as “rare” at<br />
Elmendorf <strong>and</strong> Fort Richardson, but occurs in low numbers in the greater Anchorage area<br />
(Rothe et al. 1983; Scher 1993; Andres 2005). Olive-sided flycatchers have been recorded in<br />
small-to-moderate numbers every year in all local breeding bird surveys (Sauer et al. 2005).<br />
