Red spot on red wing blackbird

16 years ago

With the coming of spring, I am getting a fairly large flock of red wing blackbirds. Initially, I notice that different birds have different red spot sizes. At first, I thought these were due to individual differences, but then I saw a black bird change its red spot. So they can vary their red spot size though some sort of physical means (probably adjust angle of the feathers).

What does the red spot signify? Why would it be larger or smaller?
