Similar
species and
how were they eliminated: |
First fall Bay-breasted Warblers are very similar however distinguished by buffy
undertail coverts, dark legs, and typically lack dark streaking on sides. Fall Pine Warblers are also similar however, distinguished from Blackpolls by lack of white primary tips, buffy tertial edges (rather than bright white), dark legs and feet, longer tails and shorter wings, heavier bills, more white on outer tail feathers, and distinct auricular pattern. |
