The Indian desert jird has a grey-brown coat with yellowish-grey belly. It is approximately 12–14 centimetres (4.7–5.5 in) long and has a tail 10–15 cm (3.9–5.9 in) long. The distinguishing characteristics include short ears, long black claws and orange incisors.
Jirds inhabit desert and barren areas preferring firm soil. They are not to be found in pure sand dunes or rocky outcrops.
The jirds are gregarious and their burrows are seen close by. Each jird will have at least two or more entrances to his burrow complex. Often the entrance is in the shade of a tree or near the trunk of bushes. They feed on seeds, roots, nuts, grasses and insects.
Difference between 'jirds' and 'gerbils'
Jirds are closely related to gerbils but are differentiated by the absence of long hind feet and the characteristic erect posture of a gerbil. The tail is generally shorter than the head and body in a jird. It also has much shorter ears. In addition, the Indian desert jird is diurnal, in comparison to the three common gerbil species found in India which are nocturnal.
