September 30, 2016 – Black-and-white Warbler (Mniotilta varia)
Requested by: @gepwin
These wood warblers are found in the eastern parts of North America, wintering in Central America and Northern South America. They feed on insects, especially moth and butterfly larvae during spring migration and the breeding season. Like creepers and nuthatches, they forage by crawling along tree trunks, hunting for insects in tree bark. Unlike other creeping birds, they climb in any direction, not just up or down. Males aggressively defend their territories from other birds. Females build cup-shaped nests on or near the ground and incubate the eggs. Both parents feed the chicks.
