(I forget if I've already mentioned this.) Ever since I put down grass seed, doves have been snacking on it. In the past, I used to try and scare them off (with varying degrees of failure...there never really was any success to speak of), but now I just go out and throw out more seed for them to eat. I started doing it because it's been relatively cold here and I want them to get enough to eat, but it has the potential added bonus that they'll eat the new seed on top and leave the stuff that I covered alone. :)
