We get owls, eagles, hawks swans etc. every year with lead poisoning. It takes a really small dose to incapacitate a bird. Spring is rough on raptors here. Everyone is out shooting ground squirrels and many of those dead squirrels lying around get picked up by birds. The actual lead fragment the bird picks up may not kill it out right, but it makes them so sick that they end up on the ground exposed to the elements, which finish them off.
Scott-actually lead bullets were a significant cause for condor extirpation. Only they didnt ingest them. They got shot. But the main factor was poison.
