Abstract:

In February 2012, the foraging habitat selection and distribution of Bar-Headed Goose(Anser indicus) in Caohai National Nature Reserve, were studied by using fixed-spot observations, plots surveys and factor analysis methods. The results showed that the wintering population number of Bar-Headed Goose in Caohai was 1 828, and distributed in all five roosting sites respectively. Human disturbance, escape and food richness, were the main factors influencing their foraging habitat selection in winter. They preferred to choose the sites with high vegetation cover, low vegetation height, far from human disturbance, close from the water, open habitats and lower elevation as their foraging sites. Based on the above habitat characteristics, the Geese selected meadow and farmland as their main foraging sites.

Key words: Bar-Headed Goose, population, foraging site, habitat selection, Caohai
