Behaviour

Brewer's blackbirds walk on the ground in fields and farmyards, often with other blackbirds.

Why they matter

Brewer's blackbirds are widespread in the West and reach Georgia in small numbers in winter. They eat many insects and weed seeds.

Nest — A cup in a shrub or tree
Eggs — Usually four to six

Living around people

  • Farmyards and feedlots attract wintering flocks.

Misconceptions
