The status of waterbird populations of Chhaya Rann Wetland Complex in Porbandar, Gujarat, India
Main Article Content
Abstract
The present investigation was undertaken to study the diversity of wetland birds in Chhaya Rann (Gujarati: Deserted land) wetland complex, situated in the urban setting of Porbandar City, in the western state of Gujarat, India. Almost 70 species belonging to 21 families of wetland birds have been reported from here with an estimated count of 35,747 and 20,981 in the year 2016 and 2015 respectively. Anatidae and Scolopacidae represent the higher number of species (11 each) followed by Ardeidae (eight species) and Laridae (seven species). The wetland complex supports one IUCN Red Listed Vulnerable species (Common Pochard Aythya ferina), six Near Threatened species (Lesser Flamingo Phoeniconaias minor, Oriental Darter Anhinga melanogaster, Dalmatian Pelican Pelecanus crispus, Black-headed Ibis Threskiornis melanocephalus, Black-tailed Godwit Limosa limosa and River Tern Sterna aurantia), and 63 Least Concern species. The wetland meets the Criteria 5 and 6 for listing as a wetland of international importance under the Ramsar Convention.
