Commmon Grackles, uncommon most of the year in our yard, thank goodness, are far too common on some early fall days. I remove feeder trays to reduce the amount of seed they eat, but the birds work hard to grip anything that gives them seed access, often sparring for position. Last week, as this acrobat and its companions raided us, I simply let the feeders go empty. We'll fill them today, with crossed fingers. Grackles are beautiful birds, very photogenic, all angles and iridescence, one of my favorites. Some days, actually, the seed is worth the photos. The bird in the second photo, being confronted (not fed!), is a juvenile, as shown by its red eyes.
