Well it is something odd that blackbirds do. The greater the difference is size in blackbirds, the more likely that they are to form single sex flocks. It is as if they act as different species until they have to mate! There are more details involved, such as different winter ranges for the sexes, but this gives you the idea of the general pattern. I am writing from Bolivia where today the blackbirds were Crested Oropendola, Chopi Blackbird and Orange-backed Troupial! NO roadrunners down here, and they would not survive the way people drive. regards Alvaro Jaramillo _______________________________________________ Do not post admin requests to the list.
