Home Range and Habitat Use of Breeding Black-Necked Cranes.

ABSTRACT: To effectively protect a species, understanding its habitat needs and threats across its life-history stages is necessary. The black-necked crane (Grus nigricollis) is an endangered wetland bird species of the Qinghai-Tibetan Plateau, which is an important grazing area in China. To overcome the conflict between increasing grazing activities and the protection of wild cranes, we investigated the variation of habitat utilization within the home range of cranes at different stages (preincubation, incubation, postfledging, and fully fledged stages). We manually tracked 13 pairs of cranes in the Zoige international wetland, used the fixed-kernel-polygon (FKP) method to determine home-range size, and used satellite images to identify different habitat types. The average home-range size was 143.3
