There are hedge sparrows nesting in the honeysuckle just outside our window. Half an hour ago I looked out to see one of the babies standing on the ground, looking lost. He's obviously too young to fly (still more fluff than feathers) but he's not a newborn or anything. He's just standing there. Next door's evil cat could come over the fence at any moment. Is there anything I can do? Presumably if I try and put him back in the nest, I'll just terrify the whole family and the mother will end up killing all her babies or something.
