Status
In the Spring, most returning migrant warbler species depend on insects and larvae that appear with the opening of leaves, but the Black-and-white Warbler feeds on wood-boring insects, bark beetles, moths, and many dormant insect larvae, which it can find in crevices on trunks and limbs of bare trees. In this way, it is like woodpeckers, creepers, and nuthatches. By foraging from bark, it need not wait for trees to leaf out, and thus it generally migrates north much earlier than other warblers, which have to wait until food becomes available on unfolding leaves.
