Breeding habitat use by sympatric and allopatric populations of Wilson’s Warblers and Yellow Warblers

We studied Wilson’s Warbler (Wilsonia pusilla) and Yellow Warbler (Dendroica petechia) habitat use in allopatric and sympatric populations in the Rocky Mountains of northern Colorado and southeastern Wyoming in order to better understand the different habitat needs and interactions of these two species.
