Nashville Warbler

These delightful, tiny warblers are returning from south of the U.S./Mexico border and breed as far north as British Columbia. Notice the yellow throat and complete white eye ring, which set it apart from the similar Mourning Warbler and MacGillivray's Warbler. (The rusty-crown patch which this photographer was lucky to capture is most often concealed). Welcome back, little beauties! Photo: Seabrooke Leckie (CC BY-NC-ND 2.0)
