As those of who you read my earlier post know, I have been having a hard time attracting birds to my feeder. Recently I have noticed a northern mockingbird guarding the feeder, swooping down--often at great speed--on smaller birds if they approach the feeder. Sometimes if a smaller bird is on the ground below feeding on the droppings, the mockingbird will check it out, driving the other bird away.
So now my bird feeder is reduced to a single mockingbird and, of course, the squirrels.
I have heard about hummingbirds becoming territorial against other hummingbirds at feeders. How frequently does this kind of behavior occur? Is aggression against other species common?
