Black-throated Blue Warbler (Setophaga caerulescens)

The Black-throated Blue Warbler (Setophaga caerulescens) is a striking migratory bird known for its vibrant plumage and distinctive song. Found in the deciduous forests of southeastern Canada during summer and the Caribbean in winter, this species primarily feeds on insects, with a diet supplemented by berries and seeds in the colder months.

Taxonomy

ID and Whereabouts

Males are easily identifiable due to their intense blue coloration on the back and black throat. Females, on the other hand, have an olive-green back with a light green throat, breast, and belly. The white stripe extending from above the eye to the beak is a distinctive feature for identification.

While searching for this beautiful bird, I observed the species only once during the spring migration in Tadoussac.
