Abstract

Wetlands in the developing world are disappearing due to bad management and urban growth, threatening the birdlife that inhabits them. The Huacho-Hualmay-Carquin wetland is located on Peru’s central coast, it has recently begun to be researched. Yet, it’s already losing ground to urbanization and public beachside development. 12 bird censuses (with two simultaneous transects: “supralittoral” and “urban”) were conducted; bird diversity and its correlation with 2 thermal-related oceanic parameters of the South Pacific (SST and ICEN) were calculated. Seventy-eight bird species were found, with abundances as high as 19,000 individuals. Species richness and abundance were higher in the supralittoral transect, while diversity was higher in the urban transect. We found correlations between the alpha diversity and abundance with both the SST and ICEN. This ecosystem exhibits high bird diversity and demonstrates the importance of studying small wetlands, as means of developing better management and conservation strategies in the region.
