Is it possible to feed doves in the backyard and to exclude pigeons from the feeder ?
Doves are the clumsiest bird of the pigeon family.. The the doves are always laying eggs on shelves only to roll off and fall to crack.. I don't know how this factoid can be used to exclude non-dove pigeons..

check with the ACLU.
that was a joke. Seriously, tho. Pigeons are doves. I think they are about the same mass. So color is what u r discriminating about. So... camera + arduino? Or feed em by hand
