Black and White Warbler on Branch
Distinctive in both plumage and behavior, the Black-and-white Warbler forages for insects while creeping along the trunks and branches of trees. It is tempting to describe the Black-and-white Warbler as a specialist wood-warbler, the only species to focus the bulk of its foraging on bark of trunks and large limbs. It is more accurate to define this species’ foraging niche as “wide” because the species frequently joins other warblers in outer branches and gleans foliage.
