Find This Bird
Black-and-white Warblers are fairly common and often intent on foraging along tree limbs, so they don’t tend to be shy. Watch for them creeping fairly rapidly on, around, and under larger branches of taller trees. Black-and-white Warblers are also quite vocal. Their song is thin, almost squeaky, but penetrating, so it’s a good way to find them. Watch for them during migration (especially early in the season): at least one or two are typically found in any reasonably good arrival of migrant warblers.
