Setophaga Striata – Blackpoll Warbler

Setophaga Striata - Blackpoll Warbler found in the US

The blackpoll warbler (Setophaga striata) is a New World warbler. They are a common migrant throughout much of North America. In October, they fly south to the Greater Antilles and the northeastern shores of South America in a non-stop long-distance migration over the open sea, averaging 2500 km, one of the greatest distance non-stop overwater flights ever recorded by a migratory songbird.

Size

These birds have a length of 5.25 in (13 cm) and a weight of 14 g (0.5 oz). Their wings could range from 8.5 in (22 cm).

Feeding

They are largely insectivorous. The species appears to be quite a generalist, preying on a vast diversity of adult and larval insects and spiders. Documented insect prey for the species includes lice, locusts, cankerworms, mosquitoes, webworms, ants, termites, gnats, aphids, and sawflies.

Habitat

Blackpoll Warblers breed mostly in spruce and tamarack forests in Canada’s boreal forests, but they also use young stands of evergreens and alder or willow thickets. During migration, they stop over in evergreen and deciduous woodlands.

Behavior

Although rather large for a warbler, blackpoll warblers are extremely easy to overlook due of their somewhat sedentary feeding technique and preference to perch in dense foliage near the canopy of the trees.
