The Indigo Bunting is an uncommon migrant and occasional breeder in southeastern Arizona, where it is most often found in riparian woodlands and grassy clearings. Males appear luminous blue in sunlight, though their plumage is actually black and refracts light to create the color. Females are brown and inconspicuous. They migrate at night, guided by the stars, and feed mainly on seeds and insects. During the breeding season, males sing persistently from treetops or powerlines, establishing territories.
