The last native sheep were seen in the Sierra Diablo in 1959, when the total population was estimated at 14. In general, mountain sheep are inhabitants of rough, rocky, mountainousterrain. They are not forest dwellers but prefer bluffs and steep slopes where the vegetation is sparse and the view unobstructed.
Beds are conspicuous indicators of the presence of sheep.
Two distinct types are utilized. The day bed, used during midday siestas, is a temporary affair constructed when and where the individual sheep decides to rest. Usually, each adult animal, particullarly among the rams, excavates a shallow depression by executing three or four pawing scratches with each forefoot before lying down. Lambs and yearlings usually omit the pawing activity. The night beds are more elaborate structures.
