These photos were taken at or near a bird feeder across a canal at the western edge of Sugden Regional Park. The first three photos are of a nonbreeding male Indigo Bunting. The last photo is of a female Indigo Bunting.
The nonbreeding Indigo Bunting is basically brown with patches of bright blue. When breeding the male becomes completely blue. The female Indigo Bunting is also basically brown with a blue tail and some blue on its wungs.
