How do bighorn sheep survive in the desert?
Southern desert bighorn sheep are adapted to a desert mountain environment with little or no permanent water. Some may go without visiting water for weeks or months, sustaining their body moisture from food and from rainwater collected in temporary rock pools. They may have the ability to lose up to 30% of their body weight and still survive. After drinking water, they quickly recover from their dehydrated condition. Wildlife ecologists are just beginning to study the importance of this adaptive strategy, which has allowed small bands of desert bighorns to survive in areas too dry for many of their predators.

How do bighorn sheep survive?
The Desert bighorn is most active during daylight, moving to traditional bedding areas at night. During the summer bighorn rest during the hot midday, often on cliffs above their water source. Rest periods are also used for chewing cud.#N#Water is critical to bighorn survival. In early spring of years with good winter rains they get enough water from the grass they eat to go without drinking. At other times they must trek to a spring or water-holding depression at least every third day. Lactating ewes need to drink almost every day. Making the trek to water is the most dangerous part of a bighorn's life. It is in the narrow canyons, where most springs occur, that the adult sheep's only significant predator, the mountain lion, Felis concolor, lies in wait. Most dead sheep found in the park are mountain lion kills.#N#Bighorn have extremely acute eyesight, which aids in jumping and gaining footholds in the steep terrain. They often watch other animals moving at a distance of almost a mile. During the rut, the bighorn rams snort loudly. The lambs bleat, and the ewes respond with a guttural "ba-aa". They also utter throaty rumbles when frightened.

What are the threats to wild sheep?
Disease is a primary threat to wild sheep populations throughout North America. Most concerning are respiratory pathogens carried by domestic sheep and goats. Although domestic sheep and goats are unaffected by these pathogens, cross-transmission during comingling events can result in severe pneumonia and potentially disastrous die-offs in wild bighorn sheep populations. Preventing disease transmission from domestic sheep and goats, in free-ranging or penned flocks, is essential to maintaining healthy and viable bighorn sheep herds. When assessing release areas for translocated bighorn, wildlife managers consider the abundance of domestic sheep and goats in an area, as well as their proximity to potential bighorn habitat. However, it is not uncommon for bighorn to go on forays or exploratory movements outside of their core ranges. There is also potential for domestic sheep and goats to escape or to not be ‘gathered’ at the end of the grazing season. Greater overlap between wild sheep and domestic sheep and goats will increase the likelihood of disease transmission. Many states rely on cooperation from neighboring stakeholders and members of the public to improve separation techniques and to alert state wildlife management agency personnel when contact between wild sheep and domestic sheep and goats is observed. Although New Mexico has not experienced as high a level of pneumonia mortality as other western states, it remains a significant risk to New Mexico bighorn sheep.
