The red patches of the Red-winged Blackbird, show the bird's alarm upon discovering an intruder on its territory. They are also displayed as a part of the courtship ritual in spring. Males hold territories of 1/8 to 1/4 acre, which they defend by singing from perches with wings spread open and red shoulder patches exposed. They can also conceal the red patch, showing only the yellow border. They are one of the most widespread and numberous birds in Florida. Males are polygynous, averaging 3 mates per breeding season.

My personal notes...
These birds are so pretty in flight...with those red patches on their wings. They have a very high pitch for a call. More timid that many other birds such as bluejays. I enjoy hearing the ones here saying..."check" in a high pitched voice.
