About the Connecticut Warbler

The Connecticut warbler (Oporornis agilis) is a small songbird of the New World warbler family. These medium-sized warblers measure 13–15 cm (5.1–5.9 in) in length, with a 22–23 cm (8.7–9.1 in) wingspan. Connecticut warblers weigh 10 g (0.35 oz) when they fledge, attaining an average weight of around 15 g (0.53 oz) as adults. However, birds preparing for migration pack on more weight to survive the strenuous journey and can weigh up to 25 g (0.88 oz). This species has light yellow underparts and olive upperparts; they have a light eye-ring, pink legs, a long tail, and a thin pointed bill. Males have a grey hood; females and immatures are more brown and have a whitish throat.

They will also supplement their diet occasionally with seeds and berries. They are "skulking" birds that usually spend their time foraging within dense, low vegetation.
