Distribution
Connecticut Warblers breed primarily in central Canada from central eastern British Columbia east to central Quebec; also in northern Minnesota and northern Great Lakes; winters in South America. Rare vagrant in the western United States. They have an unusual migration pattern, moving north through the center of North America in spring and south along the Atlantic coast in the fall.
Taxonomy
This is a monotypic species. Possibly Hybridizes with Mourning Warbler.
Habitat
Their breeding habitat is bogs or open deciduous woods near water, especially with poplar or aspen, in central Canada and states bordering the Great Lakes. The nest is an open cup well-concealed in moss or a clump of grass.
Behaviour
They are fairly elusive birds, but their numbers may be declining due to loss of winter habitat.
