Ball Python aka Python regius

The diet of the ball python in the wild consists mostly of small mammals such as rodents, shrews and birds. Young ball pythons of less than 70 cm (28 in) prey foremost on small birds. Ball pythons longer than 100 cm (39 in) prey foremost on small mammals. Males prey more frequently on birds, and females more frequently on mammals. Most captive ball pythons accept common rats and mice, and some eat birds, such as chicken and quail
