Site details


Site description: The IBA includes the Crested Ibis breeding area in Yang Xian, the night-time roost at Caoba, and the loafing areas. The breeding area of Crested Ibis is located in the north-western part of Yang Xian (about 28,000 ha), with up to 16 nesting sites. The birds will pair up and build nests in January, and depart to the loafing area in June. The night-time roost at Caoba (14 ha) is less than 1 km from the Crested Ibis captive-breeding centre, and is the only known night-time roost of the species. The autumn population can be up to 51 birds. The captive-breeding centre will attract wild Crested Ibis from time to time, which is a possible reason of the location of the night time roost. A pair bred in this area in 1996 and 1997, raised three and two birds respectively. The loafing area of Crested Ibis (about 40,000 ha) extends 25 km from east to west, and 20 km from north to south., and there are intensive agricultural activities within the area; Crested Ibis frequent this area in summer and autumn, and subadult birds remain there in winter and spring.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance because it meets one or more previously established criteria and thresholds for identifying sites of biodiversity importance (including Important Bird and Biodiversity Areas, Alliance for Zero Extinction sites, and Key Biodiversity Areas)
Additional biodiversity: Non-bird biodiversity: No information.
