Black-and-white Warbler!

My daughter and I spotted three this morning, where the red pine woods meet the red maple swamp. They were circling up and down tree trunks like nuthatches.

One of the earliest-arriving migrant warblers, the Black-and-white Warbler’s thin, squeaky song is one of the first signs that spring birding has sprung. This crisply striped bundle of black and white feathers creeps along tree trunks and branches like a nimble nuthatch, probing the bark for insects with its slightly downcurved bill.
