Careful observation should help you make a correct determination. If the bird is in a street, place it under a nearby bush. If there are dogs or cats present, try to keep them away from the area for a few hours. Never unnecessarily handle or move the fledgling from the area where it was found. Baby blue jays are slow to mature, so the fledgling stage will generally take longer for them.
Mother deer typically leave their fawns bedded down while they are away foraging.
If the fawn is not crying, is not covered with fire ants, the eyes are not swollen and there are no visible wounds, do not handle or disturb it. Your presence will only cause unnecessary stress for the fawn.
