Abstract


We employed distance sampling using line transect method to gather data on abundance of Red-wattled Lapwing (Vanellus indicus) in various habitats (wetland habitat, croplands, urban habitat and scrubland) during different seasons (winter: December, 2013 to February, 2014; summer: April-June, 2014) at Chakwal, Rawalpindi and Islamabad, Pakistan. We recorded highest population density (9.27 individuals ha-1) of Red-wattled Lapwing from wetland area while lowest population density from cropland area (0.38 individuals ha-1) during the study period. We recorded highest population density (3.69 individuals ha-1) from wetland areas during winter while urban and scrubland areas had highest population density (0.13 individuals ha-1 each) during summer. The univariate generalized linear model revealed that number of individuals Red-wattled Lapwing differed significantly among the habitats (F (3, 48) = 5. 73, P= 0. 002) but non-significantly during the seasons (F (3, 48) = 2. 57, P= 0. 11). The variations in abundance among various habitat types in a given season revealed occurrence of the species in a particular habitat such as urban and cropland areas in summer associated with natural history events such as breeding.
