The stunning turquoises, blues and purples of this bird are a “trick of the light.”

Indigo Bunting, male
Like the ruby throats of our hummingbirds, the science of light diffraction creates the illusion of indigo on this bunting. Also, for folks who live in their winter ranges (Caribbean, Central and northern South America), this species will not look blue – their feathers change to a tawny brown.

Indigo Bunting, female
Females hold almost all the responsibility in nest building, caring for the eggs and raising the young. Perhaps this is the reason they wear feathers of inconspicuous browns. Once the young leave the nest, they learn their songs from “neighborhood” males (rather than their male parent). These communities share unique versions of songs that can be heard for 20 years. The tunes vary when individuals add their own unique stylings to the melodies.
Bird Bits
Fun Facts: As nighttime migrants, the Indigo Bunting was one of the first species to educate us about how birds navigate by the stars.
Habitat: edges of woods and fields, weedy and brushy perimeters, rural roadsides
Conservation Note: Due to the pressures of urbanization, mowing roadsides and illegal trapping and hunting on their winter grounds, the Indigo Bunting population has declined an estimated 28% in the last 40 years.
