So a month ago, the contractor finishing up our bathroom remodel and window replacements had left his ladder leaning against the house and a pair of robins built a nest on one of the rungs. It was hardly more than a foot from our bedroom window. But the contractor obviously needed his ladder back and his worker did the birds a kindness and built a little shelf out of scrap wood, nailed it to the side of the house, and moved the nest to it.
We thought the birds might not come back but then we found little blue eggs in them and, eventually, the mama sitting on them. There were at least four eggs and after a couple of weeks, they hatched. The robins would swoop at the window whenever the cats hopped up to stare at them and fail to pounce down on them through the glass (dumb cats!)
Last Saturday morning, fairly early, I heard loud crow calls and some bumping from the wall the nest was attached to. My wife discovered later in the morning that none of the babies were in the nest. The asshole crow(s) had pillaged the robin chicks. The parents had put up a fight and two of the babies had either been dropped or scattered from the nest in the melee. We got them back into the nest while the anxious mom and dad fluttered from tree to tree and even swooped at us when one of the babies freaked out. But they accepted the babies back in the nest and kept feeding them huge beakfuls of bugs.
They only needed four or five more days to be able to leave the next, by my estimation. But the crow(s) came back. The parents put up a fight again but one the babies neck was snapped, either by the crow or when the crow dropped it. The other we found in the grass alive. It might have a sprain on its wing but it is too hard to tell. Still, we got it back into the nest.
The idiot bird jumped right back out of the nest, clearly not able to fly, but trying. It even fluttered a good 50 feet and we lost it for a while. I'm not sure if the poor thing will make it, but we've done what we can. The nest has a cardboard shade over it and maybe the chick will sit tight for another day or two. If we're lucky, the crows will stay away that long and the chick won't have been hurt, just bad at flying still.
Nature is damn cruel. And so are crows.
