The Connecticut warbler (Oporornis agilis) is a small songbird of the New World warbler family.
This species has light yellow underparts and olive upper-parts; 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.
The song of this bird is a loud repeated cheepa-cheepa. It's similar in pitch to the Kentucky warbler and the Ovenbird. The call is a nasal pitch, it sounds like a raspy "witch". Like many songbirds, its song is heard during breeding season but rarely during the fall.
