The Philippines has few species of large mammals. The domesticated water buffalo, or carabao, is common throughout the islands. Small mammals are more numerous, including monkeys, rodents, bats, and shrews; several species of deer, including a dwarf deer; mongooses; and porcupines, found only on Palawan. Reptiles and birds are greater than mammals. The islands have 196 species of birds, including colorful parrots and the endangered monkey-eating eagle.
