- Abstract
By using the methods of fixed-spot observation, GPS positioning, sampling plot investigation, and factor analysis, the forage habitat selection of white-naped crane (Grus vipio) during its incubation period in Zhalong Wetland was studied from April to May 2002-2008. In the study area, the crane during its incubation period chose a variety of habitat types as its forage habitat, among which, wetland (reed swamp) was the main one, occupying 74. 36% of the total, followed by farmland. The forage habitat included four elements, i. e., habitat identification, food, water, and cover, and the main selection criteria were the identification factor and energy factor, followed by eating feasibility factor, security distance factor, and concealment factor. The forage habitat selection of the crane during its incubation period had two levels (macro- and microhabitat) and three courses (forage habitat type choice, forage area choice, and forage microhabitat choice).
