Fauna of the National Parks — No. 6
The Bighorn of Death Valley
National Park Service Arrowhead

bighorn
Figure 57.—The remarkable synchronization of movement pictured here is the rule, not the exception. Every effort seems to be made to insure a perfect head-on and balanced contact. Note that both heads are tilted to the same side.

bighorn
Figure 58.—Sometimes the heads are tilted in opposite directions, resulting in a blow on the forehead itself instead of on the horns, but the encounter is still head-on and in balance.

bighorn
Figure 59.—Occasionally one slips or miscalculates and a severe neck-twisting or nose-smashing can result. Tabby, the ram on the left, has a scar on the right side. Broken Nose has a dark patch on the left horn. Tabby has not watered for 3 days, and shows the gauntness and rough coat of dehydration.

bighorn
Figure 60.—This 7-year-old ewe was captured and brought to the Desert Game Range in 1947 when she was a lamb. Here 6-week-old lamb was born in 1954 and registered in the Desert Game Range genealogy as "female No. 7."

bighorn
Figure 61.—This is "female No. 7," when 6 weeks old in April 1954. At this age, the previously ill-defined rump patch turns white. The horns have not appeared, but the characteristic tufts of hair often are mistaken for beginning horns.

bighorn
Figure 62.—"Female No. 7," when 7 months old in October 1954.

bighorn
Figure 63.—"Female No. 7," when 2 years and 7 months old in October 1956, accompanied by her 6-1/2-month-old ewe lamb, which was born on April 4, 1956. These relatively inconspicuous "extra" growth rings appear fairly often in ewes.
