Appearance: The common grackle is a large bird about 12.5″ long bird with iridescent blue purple and bronze. Their eyes are yellow and they have long flared tails. The female is similar with less vibrant coloring (browner) and a shorter tail.

Diet: Insects, grains, seeds, fruit, scavenged garbage.

Feeder food: Sunflower seeds, black-oil sunflower seeds.

Habitat: Fields with scattered trees, open woodlands, farmlands, and marshes. Common in suburban yards.

Nesting: Bulky cup-shaped nest of twigs placed 3-20′ high in a conifer tree. 3-5 eggs incubated for 12-15 days. Young fledge at about 12-15 days.

Migration: Common grackles are migrators. While many remain in their year-round range all four seasons, many head north in spring (as far north as Canada’s Northwest Territories) to breed and raise their young. Then in the fall, they head back south into their year-round range. A small part of the population pushes further southwest of Texas.
