Pygmy rabbit

The pygmy rabbit (''Brachylagus idahoensis'') is a North American rabbit, and is one of only two rabbit species in America to dig its own burrow . The pygmy rabbit differs significantly from species within either the ''Lepus'' (hare) or ''Sylvilagus'' (cottontail) genera and is generally considered to be within the monotypic genus ''Brachylagus''. One isolated population, the Columbia Basin Pygmy Rabbit, is listed as an endangered species by the U.S. Federal government, though the International Union for Conservation of Nature lists the species as lower risk.
The pygmy rabbit is the world's smallest leporid,〔(Meet the World's Smallest Rabbit ), October 14, 2009〕 with mean adult weights from , and a body length from ; females are slightly larger than males. The pygmy rabbit is distinguishable from other leporids by its small size, short ears, gray color, small hind legs, and lack of white fur on the tail.
==Distribution==
The range of the pygmy rabbit includes most of the Great Basin and some of the adjacent intermountain areas of the western United States.〔 Pygmy rabbits are found in southwestern Montana from the extreme southwest corner near the Idaho border north to Dillon and Bannack in Beaverhead County.〔 Distribution continues west to southern Idaho and southern Oregon and south to northern Utah, northern Nevada, and eastern California. Isolated populations occur in east-central Washington〔 and Wyoming.
The elevational range of pygmy rabbits in Nevada extends from and in California from .〔
The last male purebred Columbia Basin pygmy rabbit, found only in the Columbia Basin of Washington State, died March 30, 2006, at the Oregon Zoo in Portland. The last purebred female died in 2008.〔(National Geographic – Editor's Note – January 2009 )〕 A crossbreeding program conducted by the Oregon Zoo, Washington State University and Northwest Trek is attempting to preserve the genetic line by breeding surviving females with the Idaho Pygmy Rabbit.〔Wiley, John K.
