The Bluejays seem to have the obvious advantage - they're smarter and far more aggressive than their opponents, but the real strength of the Mourning Dove is that it's dumb as shit and while under direct attack from the Jays, just fucking *stares* at them placidly, as if to say, "What are you going to do, stab me?" And then the Bluejay stabs them.
The wildcards are the Brown-Headed Cowbirds. Whose side are they on? They don't seem bothered by the presence of other birds, and they don't seem to mind sharing the feeder with the chipmunks. They don't take shit from the Jays, but neither do they go on the offensive.
No, they're playing a different game.
I think they have an uneasy alliance with the Sparrows.
