It is less common in amphibians, reptiles, and mammals. Among volant vertebrates, it is much more common in birds than in bats, and birds migrate much longer distances, on average, than bats. Nonetheless, a considerable number of bats, including both temperate and tropical species, undergo significant seasonal movements between habitats
