They are prohibited in California. As desert dwellers, gerbils dig long burrows in order to escape the harsh temperatures; however, unlike hamsters, gerbils are not nocturnal. Gerbils are active most during the evening and morning, times in which the weather is calmest, making them primarily crepuscular.
Gerbillinae is one of the subfamilies of the rodent family Muridae and includes the gerbils, jirds, and sand rats. Once known as desert rats, the subfamily includes about 110 species of African, Indian, and Asian rodents, including sand rats and jirds, all of which are adapted to arid habitats.
Great gerbils live in family groups and occupy one burrow per family. [3] Their burrows can be fairly extensive with separate chambers for nests and food storage. Great gerbils spend considerably more time in the burrows during winter, but do not hibernate. They are predominantly diurnal. Food consists mostly of vegetable matter. [2]
The North African gerbil lives in a burrow that it digs and is a terrestrial and nocturnal animal. The timing of breeding depends on location, but in Egypt coincides with the winter rains, and in North Sudan follows the short wet season in September to November. The litter size is about five pups. The diet of this rodent has not been studied. [3]
Its sense accordingly differs from diurnal and nocturnal behavior, which respectively peak during hours of daytime and night. The distinction is not absolute, because crepuscular animals may also be active on a bright moonlit night or on a dull day. Some animals casually described as nocturnal are in fact crepuscular. [2]
The greater Egyptian gerbil is nocturnal and terrestrial, excavating a burrow in which it lives during the day; this is similar to the burrow dug by the lesser Egyptian gerbil, which descends to a depth of 60 to 80 cm (24 to 31 in). This gerbil often lives in colonies. It feeds on seeds and grasses, storing some in its burrow.
The Flower’s gerbil is nocturnal and lives in burrows. It feeds on insects and plants. The breeding season of Flower’s gerbil is known to be from May to December. [2] A female's litter usually contains four young after a gestation period of 20 to 22 days. [2] The young are born with closed eyes and are hairless. except for some bristles on ...
