Black-throated blue warbler
One of my favourite warblers, the black throated blue is always identifiable by the little white spot, the handkerchief, on its side.
It is nice having a bird that is easy to identify.
This one was seen on Spicebush Trail in Rondeau.
Setophaga caerulescens
.A bird of the deep forest, the Black-throated Blue Warbler breeds in the northeastern United States and southeastern Canada. On migration to its Caribbean wintering grounds it can be seen in a variety of habitats, including parks and gardens.
The sexes of the Black-throated Blue Warbler look so different that they were originally described as two different species.
