Figure 4. Nanny with young kid, taken in late June. Head and neck are shed of winter hair while rest of winter coat remains. By using November 19 as an average breeding date (midway between the earliest — November 13, and the latest — November 24 — mating activity seen) and May 29 as an average kidding time (midway between iMay 24 — the earliest, and June 3 — the latest date of parturition seen) I have tentatively determined a gestation period of 191 days. This is almost two weeks longer than the 178 days reported by Seton (1927) and much longer than the 147 days reported by Keneth (i?i Rand, 1948). I believe the 191 day gestation period is probably accurate within a week in either direction for goats in this area. Young Very young goats closely resemble the young of bighorn sheep. Their coat is white but their size and appearance are similar. By the time the young goats are five or six weeks old, this resemblance has been lost and they begin to look like the adult goat. Kids begin to make use of grass and browse soon after birth. It was not unusual to see kids two or three days old nibbling the same bush as their mothers. Brandborg (1955) also noted that kids took forage. The first few days after their kids are born, the mothers remained constantly within a few feet of them. I never saw a mother goat go away and leave her young hidden during their first days of life as cow elk or doe mule deer (Odocoileiis hemiomis) will do. This agrees with observations of Casebeer et al (1950). When the nanny is feeding, her kid is immediately by her side or bedded within a few feet of her. Within two weeks, however,
