Bluebirds have been the traditional avian harbinger of spring throughout our nation’s history. However, with the various pressures applied by habitat conversion, heavy pesticide application, and the introduction of exotic competitors like house sparrows and starlings, the bluebird is a species few city dwellers will ever see in their neighborhoods again. On the other hand, human activity has been generally good for the red-winged blackbird and throughout the region---city, suburb and rural areas alike—wherever there is tall grass and some standing water, male red-winged blackbirds are arriving in droves.
As with many bird species, the males arrive first to stake out the best territories; he with the best territory will have the most mating opportunities later in the spring when the females arrive. The male proclaims his fiefdom with a loud metallic call that sounds a bit like a squeaky swing set. At the same time he leans forward to display his eponymous red wings, really just a patch of bright red feathers on his wrist that contrast well with the rest of his jet black body. While it’s a small patch of color, it makes all the difference. The bigger and more intense patches attract the most mates.
In fact, scientists have influenced mating opportunities by experimentally cutting the red feathers off of some males and gluing them on to others. Much like humans who are stereotypically impressed by a man driving a red sports car, regardless of his age or personality, female red-winged blackbirds apparently look no deeper than the red patches on a boys wrists.

Once the male has established his territory, he will aggressively defend it against all interlopers, including you. It can be fun, and a little daunting, to walk past a breeding colony of red-winged blackbirds. Most will simply scream at you but usually one will sneak up behind you and, when you are not looking, he may drop out of the sky and hit you on the back of the head. Keep your eyes to the sky this spring.
