Hi I remember years ago being in central Mexico, late winter-early spring, where enormous flocks of Yellow-headed Blackbirds wintered. The spectacle was made even more dramatic, because of the tendency of blackbirds to separate into same sex flocks. So image a huge flock, containing many thousands of male Yellow-headed Blackbirds all swooping and swerving, with the flock size constantly shifting and re-formulating in size. From a distant a flock can appear like a huge yellow ball, because of the dominate coloration of the yellow on head of males. It’s is a visualization that I’ll never forget.
