Second, baby crows often leave the nest a couple of days before they can fly. This strikes me as an exceptionally bad idea, but it's what they do.
During that first week or two out of the nest, all bets are off. Crow parents are a giant bundle of stress hormones. Crows you don't know will attack; even your best crow friends may be untrustworthy.
Just imagine what they are going through, give them time, and when the fledglings are flying readily they'll be back to their old selves.
And this brings me to today's curious coda. Last week, we lost a silver ring around the house or yard.
As I mentioned earlier, my crows don't tend to bring gifts. But this morning as I went out to give them their snack, there was the ring, plain as day, right in the spot where I feed them.
Now it's entirely possible that we lost it there and didn't notice for a few days. But it seems odd given how many times I've passed that spot since. I have my guesses, but I'll let you make up your mind.
