Another common form of live food, most commonly used to feed snakes, is small rodents. The most commonly known small rodent used for live food is likely the mouse; many pet stores which carry snakes or cater to snake owners also carry "feeder mice" for this reason (see Fancy mouse).
Mealworms are typically used as a food source for reptile and avian pets. They are also provided to wild birds in bird feeders, particularly during the nesting season when birds are raising their young and appreciate a ready food supply. Mealworms are high in protein, which makes them especially useful as a food source. They are also commonly used for fishing bait.
