Physical Description
Size
Diagnostic Description
Differs from other subspecies in mean values for various external and cranial characters; most similar to Exilis, smaller than BREVINASUS in length of tail (137.7, 137.4, 148.8, in mm, respectively, for NITRATOIDES, Exilis and BREVINASUS), length of hind foot (34.0, 33.4, 36.0), width of bulla (21.6, 21.7, 22.6), and condylobasal length (29.9, 29.7, 31.4); NITRATOIDES has the least amount of red pigment, BREVINASUS the most (see Best 1991).

Ecology
Habitat
Migration
Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

NatureServe Conservation Status
Rounded Global Status Rank: T1 - Critically Imperiled
Reasons: Small range in southern California, much reduced by agricultural development; threats include flooding, development, illegal or misuse of rodenticides, or improper vegetation management (grazing, fire); development demands continue to increase.

Tipton kangaroo rat
The Tipton kangaroo rat (Dipodomys nitratoides nitratoides), is a subspecies of the San Joaquin kangaroo rat, a rodent in the Heteromyidae family.[1] [2] [3]
Contents |
Description
Adult Tipton kangaroo rats have small forefeet, exceptionally large hind feet, and long tail.[4] They have a head and body length of about 100 to 110 millimeters and weigh approximately 35 to 38 grams. The tail length is about 125 to 130 millimeters in length. This subspecies is larger than the Fresno kangaroo rat and smaller than the short-nosed kangaroo rat (D. nitratoides brevinasus).[5]
Distribution
This subspecies lives in ground burrows between the Kern National Wildlife Refuge, Delano, and the natural lands surrounding Lamont (southeast of Bakersfield), Kern County, at the Coles Levee Ecosystem Preserve and in other scattered areas to the south in Kern County, in areas west of Tipton, Pixley, and Earlimart, Pixley National Wildlife Refuge, Allensworth Ecological Reserve, and Allensworth State Historical Park in Tulare County.[6]
Diet
Tipton kangaroo rats eat mainly seeds. They also consume some insects and small amounts of herbaceous vegetation when available.
