Desert bighorn sheep
On Monday, April 26, 2010, a female desert bighorn sheep was born at the Los Angeles Zoo.
Desert bighorn sheep are native to the high mountains and deserts of the south western United States and northern Mexico. Preferring to reside in places with rocky terrain and access to water, they completely avoid forested areas. In the wild, a herd is comprised of females and their lambs. When the males reach the age of two, they separate from the herd and set off by themselves in bachelor groups.
As male desert bighorn sheep mature, they develop massive spiraled horns that may add up to one-third of their total body weight. Females have much smaller horns. However, both sexes have excellent vision and hearing as well as an innate ability for climbing rugged terrain.
