Red-winged Blackbird

Agelaius phoeniceus. Abundant in marshes and fields. Females and immature males resemble large sparrows, but are longer billed and more heavily streaked, often with a tinge of red on shoulder or throat. Feed, and fly, and roost in huge flocks. We saw one who was harassing a doe running along our long driveway. It pecked the doe several times on the rump.
