What the Indigo Bunting song sounds like

The male Indigo Bunting's song is a bright, upbeat series of musical phrases, often in couplets. A typical song is rendered as "sweet sweet chew chew sweet sweet," a high-pitched, hurried warble lasting 2–4 seconds. Each male sings one complex song composed of a set of phrases, which he repeats throughout his life. The song has a bouncy, cheerful quality and is delivered from treetops or wires from dawn to dusk in summer.

How to find the bird singing it

Edges of woods, brushy fields, and roadsides. Prefers patchy open habitats with low shrubs and nearby trees. Often found in overgrown weedy fields, hedgerows, powerline cuts, young regenerating forests, and along woodland edges. During migration, may gather in flocks to feed in agricultural fields or grasslands. Winters in shrubby clearings and forest edges in the tropics. Readily uses second-growth and disturbed areas.

  • Male breeding plumage: Vibrant indigo blue overall with slightly darker wing and tail feathers, and black lores (around the base of the bill).
  • Female appearance: Warm brown or tan with faint streaks and usually a tinge of bluish on the tail or shoulders. Whitish throat and small patch of darker markings on the breast sides.
  • Size and shape: Small bunting with a short, thick seed-eating bill. Both sexes show an unstreaked throat and a small patch of darker markings on the breast sides.

When you'll hear it

Spring

Males arrive in breeding plumage with brilliant blue coloration. They actively establish territories and sing persistently from high perches.

Summer

Adult males are bright blue throughout breeding season. Females tend to nestlings. By late summer, males begin molting into brownish eclipse plumage with only hints of blue.

Fall

Post-breeding males look more like females with brown plumage and blue patches. Birds form loose flocks for migration southward, becoming scarce in the U.S. by October.

Winter

Largely absent from the U.S. except in southern Florida and the southwest border. Winters in tropical habitats where males maintain their dull non-breeding plumage until late winter when blue feathers begin to appear again.
