The red-winged blackbird (Agelaius phoeniceus) belongs to the family of birds (Icteridae) that include meadowlarks, orioles, and grackles. Adult birds vary in size from 7 – 9.5 inches. Adult males are black with a red and yellow shoulder patch at the bend of the wings. Females look much like a large sparrow with a heavy, sharp pointed bill and heavy striping below and a light stripe over the eye. Immature birds resemble a dark female with a reddish shoulder patch. Adult males are one of the most beautiful and unmistakable species observed by birders.

LIFE HISTORY AND ECOLOGY:
When migrating, males often arrive before females in the spring. The red-winged blackbird is a gregarious species that is often found singing from reeds, trees, or fence posts. It is not uncommon to view this species feeding at bird feeders. Nests are bulky, bowl shaped structures built from grasses and are usually found attached to reeds in marshes, in bushes or even grassland habitats. Females lay 3-5 pale, bluish-green eggs marked with brown, purple, and black.
