Chestnut-sided Warbler begins fall migration

During the breeding season (spring-summer), the chestnut-sided warbler has a yellow cap, black mask, plain white belly, yellowish wing bars and chestnut streaks along his sides. The breeding female is a little duller. After nesting they undergo a complete transformation. They have a gray and olive green coat with a white eye ring.

The Chestnut-sided Warbler is insectivorous predominately. Look for them as they hop from branch to branch with their tail cocked in search for insects on the underside of leaves. They may also be seen at suet feeders and bird baths.

They are nocturnal migrants that may join other warbler flocks and occasionally forage with them from mid-August to October as they fly south to spend their winter in Central America.

Watch the migration from spring to fall on eBird's occurrence map: http://ebird.org/chestnut-sided-warbler migration.  It's interesting to note that the flight up in May is through Texas and the flight down in the fall is through Florida.
