Warbling Flycatcher

Rather plain, but with a cheery warbled song, the Warbling Vireo is a common summer bird in leafy groves and open woods from coast to coast. Because it avoids solid tracts of mature, unbroken forest, it is probably more common and widespread today than it was when the Pilgrims landed. Some scientists believe that eastern and western Warbling Vireos may represent two different species; if that is true, then the two are very difficult to tell apart in the wild.
