If a bird is only partially feathered and, on the ground, return it to the nest if possible (usually not possible because most nests are too high). Rescue a bird that is weak, or ill (or if it remains in the same spot for an hour or more), has a lame wing or leg, is bleeding or injured, cat attack (more lethal than dog, but dog bites should be brought in promptly also); suffering from heat, cold, or other weather exposure problems; emaciation, or is turning in circles (often a clue that an animal is blind). If there are flies, ants or other insects on it, (remove them!) or if it' is in obvious danger bring the bird or mammal to us immediately. Remember, parent birds can't pick up a youngster in its beak and return it to the nest.
