No systematic study of the ecology of the Short-beak Echidna has been published. There have been studies of several aspects of their ecological behaviour. Short-beaked Echidnas live alone and apart from the burrow created for rearing young; they have no fixed shelter or nest site. They do not have a home territory, but range over a wide area. Short-beaked Echidnas are usually active in the daytime; however, they have problems in hot weather, because they have no sweat glands and do not pant. Therefore, in warm weather they change their pattern of activity, becoming crepuscular (active at dawn or dusk) or nocturnal (active in the night). They can tolerate cold temperatures, and hibernate during the winter in very cold regions.
