Black and White Warbler

 

Black-and-white Warblers are medium-sized warblers (small songbirds). They have a fairly long, slightly downcurved bill. The head often appears somewhat flat and streamlined, with a short neck. The wings are long and the tail is short.

Black-and-white Warblers act more like nuthatches than warblers, foraging for hidden insects in the bark of trees by creeping up, down, and around branches and trunks. Despite their arboreal foraging habits, they nest on the ground at the bases of trees.

Deciduous forest and mixed forest are the preferred summer habitats of Black-and-white Warblers, usually with trees of mixed ages that provide a variety of foraging substrates. Cornell All About Birds
