About These Birds
American Redstart
The American Redstart is an active wood warbler weighing about 8 g with a 12.4 cm wingspan, with males showing bold black-and-orange plumage. It fans its tail and droops its wings to flush insects from foliage, a distinctive foraging behavior observed across its North American breeding range.
Blackpoll Warbler
The Blackpoll Warbler is a small, near-threatened warbler; breeding males have a black cap, white cheeks, and heavily black-streaked white underparts, while females and nonbreeding birds are streaked olive-green. It breeds in boreal forest from Alaska across Canada to Newfoundland, undertaking one of the longest overwater migrations of any songbird, flying nonstop to South America for winter. It feeds on insects and berries.
