Blue Grosbeak

The husky warbling song of the Blue Grosbeak is a common sound in summer around thickets and hedgerows in the southern states. Often the bird hides in those thickets; sometimes it perches up in the open, looking like an overgrown Indigo Bunting, flicking and spreading its tail in a nervous action. During migration, and in winter in the tropics, Blue Grosbeaks may gather in flocks to feed in open weedy fields.
