Worm-eating Warbler, Helmitheros vermivorum

Worm-eating Warbler
Male Worm-eating Warblers are not as colorful as most male warblers, and indeed their plumage is not distinguishable
from that of the females of the species. But they do sing, both to establish territory and attract a mate, and these birds
made clear they were males by singing. This was in Shawnee Forest in southeastern Ohio in late April, when the
male warblers were just arriving, the redbud was blooming, but most of the females were yet to arrive, and most of the
leaves were just beginning to show themselves.
