It took some doing but I think I got them all straightened out. The Juvenile cowbirds were the tough ones as not that many bird books give you what the juvenile birds look like and the cowbirds are very different from the elders. Plus, I caught some males in-between as they were growing in their adult feathers. I couldn't find those at all until I saw a juvenile and adult male together and I worked it out. This backyard birding is tough. Looking forward to see if different types of birds start to visit in the fall. We shall see. Oh, and the damn squirrels figured out how to jump the gap from the fence to get on the plate so I am going to have to move the whole contraption again. Geeezz.....
