I just witnessed two Blue Jays attacking and killing a young Robin while the parents tried like hell to fight to save it. The Jays actually carried the young bird(bigger than a hatchling, about half the size of the parents)off into the neighbors’ yard when I went outside to see if I could do anything (or pick up the dead bird before my dog found it). I’ve never seen that happen before and I pay attention to the birds and bugs around here. Yipes.
