Abstract
Between 7 May and 5 August 1991 we counted 298 black-necked cranes (Grus nigricollis) on breeding grounds in central and southwestern Tibet Autonomous Region (TAR). We confirmed breeding for 32 pairs: we found 17 nests at 8 wetland sites and 15 broods of 25 chicks, including 5 transitional fledglings. Mean altitude of nest wetlands was 4694 m. Nest height averaged 21.3 em above water, and water depth averaged 14.8 em. Black-necked cranes nested a mean of 140.5 m from uplands and 803 m from potential disturbance such as a road or dwelling. Mean nest initiation date was 28 May.
