The Connecticut Warbler Oporornis agilis is a small songbird of the New World warbler family.

These 15 cm long birds have light yellow underparts and olive upperparts; they have a light eye ring, pink legs, a long tail, pale wing bars and a thin pointed bill. Males have a grey hood; female and immatures are more brown and have a whitish throat.

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.

These birds migrate to the Amazon River area in South America in winter.

They forage on the ground, picking among dead leaves, or hop along branches. These birds mainly eat insects and sometimes seeds and berries.

The song of this bird is a loud repeated cheepa-cheepa. The call is a nasal pitch.

Despite its name, this bird would probably only visit Connecticut during migration. They are fairly elusive birds, but their numbers may be declining due to loss of winter habitat.
