Connecticut Warblers breed in southern Canada and the northern Great Lakes and can be seen migrating across the Midwest and down to Florida on their way to South America for winter.

Habitat And Diet

You can find Connecticut Warblers in remote areas, such as bogs with deciduous woods with poplar, spruce, tamarack, or aspen. When migrating, they select low, wet woods and damp thickets. 

Connecticut Warblers are skulkers. They spend their time foraging under dense or low leafy vegetation. They usually search for spiders, snails, and caterpillars, picking among dead leaves and hopping between branches.

Nests of Connecticut Warblers are made of grass and often hidden in thick clumps of moss. The female lays three to five eggs that take around twelve days to hatch. 

Fun Fact:

Connecticut Warblers are elusive birds and have different migratory routes, which makes it hard for scientists to learn more about them.
