Pigeons are really dumb birds, how they have survived as a species is a mystery to me. We have a few pairs on the farm that have had babies and out of the 6-8 that have made it to maturity, 2 of them we had to rescue cause they just jumped out of the nest and couldn't fly yet. We'd put them back in the nest for a few days and then just give up and raise them in the aviary until they were fully grown and then release them. Awesome birds as pets, but dumb as a box of rocks in the wild.
