In other light, the "Indigo Bunting" male looks black, which is what he really is, as he has no natural blue pigmentation. The diffraction of light through the structure of the feathers makes them appear blue. His wing and tail feathers are a darker blue than the rest of him. This bunting is a common sight throughout the eastern half of the United States.
Brown above, lighter below; dark wing and tail feathers.
This sparrow sized bird breeds from southeastern Saskatchewan east to New Brunswick, and south to central Arizona, Texas, the Gulf Coast and northern Florida.
Calls or song.
The bunting's song consists of a sequence of high warbling notes, often paired, and sometimes rendered as "ti ti whee zerre zerre". They use a brief, "chip" in many situations, and "tink" and "aaaa" when alarmed.
Population and distribution.
The "Indigo Bunting" is a "weed and insect killer", making itself beneficial to farmers and fruit growers. They are a familiar sight alongside rural roads and railroad right-of-ways, wherever woodland meets open area. They winter in Florida and the tropics.
The female bunting lays three or four pale blue eggs in a woven cup made of leaves and grass. This is located in a sapling or thick bush near the ground.
