A few warblers are starting to show up at Rondeau.
Mostly black-throated greens, yellow rumps, yellows an d a few blackburnians.
Also the black and white warblers are being seen.
I always associate black and whites with the start of the spring migration of the wood warblers.
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.
Black-and-white Warblers have an extra-long hind claw and heavier legs than other wood-warblers, which help them hold onto and move around on bark.
