In the spring I saw these 2 red winged blackbirds hopping in & outta' my bushes behind the house. Yesterday Marton noticed Mr, Redwing hanging out on the electric wires, then I saw Mrs. come from behind the house to the feeders. I heard a bunch of peeping behind the house. So i look in the bushes, and sure enough theres a nest!
One of the most abundant birds across North America, and one of the most boldly colored, the Red-winged Blackbird is a familiar sight atop cattails, along soggy roadsides, and on telephone wires. Glossy-black males have scarlet-and-yellow shoulder patches they can puff up or hide depending on how confident they feel. Females are a subdued, streaky brown, almost like a large, dark sparrow. In the North, their early arrival and tumbling song are happy indications of the return of spring.
