Listen up EVERYONE. Robins are songbirds and therefore protected. Raiding nests to feed your snakes is ILLEGAL. If you want to feed baby birds to your snakes, then raid the nests of European starlings or House sparrows if you live in the U.S. You may kill and raid the nests of those two non-native birds all you want. I think I mentioned it before, it's pretty easy to get house sparrows or starlings to nest in a crude, cheaply made nest box. Wait for the chicks to hatch and snag them up. The birds will simply lay more eggs and hatch those out too, up to 3 times before they give up. Raid a robins nest AFTER incubation or hatching commences, and the robin will never use that spot again.
