Nest-site selection of mallard (Anas platyrhynchos) in Daqing Longfeng Wetland
Main environment factors for nest-site selection of mallard (Anas platyrhynchos) were surveyed with direct observation and sampling method in Longfeng Wetland from May to July 2016.The environmental factors were investigated for 38 mallard's nests and 38 adjacent nonenest sites as contrast samples.The results showed that the nest-site selection of the mallard was specific and non-random.The main environment factors in nest-site selection of mallard were the density,height and coverage of vegetation,the proportion of bare land and the proportion of hay,successively.These factors suggested that mallard preferred the environment with higher concealment,higher herb coverage and being far away from the road.Accordingly,the concealment became the most important factor for nest-site selection of A.platyrhynchos.
