Behaviour

Indigo buntings migrate at night, using the stars to navigate — a finding from pioneering experiments in planetariums. Young males learn their songs from neighbours.

Why they matter

Indigo buntings have taught scientists much about how birds navigate by the stars. They eat many insects and seeds in old fields.

Reproduction and lifecycle

Nest — A cup in a shrub
Eggs — Usually three or four
Incubation — About 12 to 14 days
Chicks — Fed by the female
Lifespan — Several years

Living around people

  • Shrubby field edges support them.

Misconceptions

  • Indigo buntings are blue from pigment. Their blue comes from the structure of their feathers.
