The Indigo Bunting is a small bird, with a length of 11.5–13 cm (4.5-5 in). It displays sexual dimorphism in its coloration; the male is a vibrant blue in the summer and a brown color during the winter months, while the female is brown year-round. The male displays brightly colored plumage during the breeding season to attract a mate. Nest-building and incubation are done solely by the female. The diet of the Indigo Bunting consists primarily of insects during the summer months and seeds during the winter months.
Did you know:
The Indigo Bunting migrates at night, using the stars for guidance. It learns its orientation to the night sky from its experience as a young bird observing the stars.
Experienced adult Indigo Buntings can return to their previous breeding sites when held captive during the winter and released far from their normal wintering area.
The sequences of notes in Indigo Bunting songs are unique to local neighborhoods. Males a few hundred meters apart generally have different songs. Males on neighboring territories often have the same or nearly identical songs.
Indigo and Lazuli buntings defend territories against each other in the western Great Plains where they occur together, share songs, and sometimes interbreed.
Song a musical series of warbling notes, each phrase given in twos. Call a sharp, thin "spit." Flight call a high buzz.»
