Demographic variation in the population of Sarus crane in and around Alwara Lake of district Kaushambi, India

Abstract

The Sarus crane, Grus antigone is a monogamous, non-migratory and world’s tallest flying bird. This is the only resident breeding crane of Indian subcontinent, prefers open habitat like marsh areas, abundantly irrigated paddy fields, grass land and wetland. Its population is gradually decreasing and now globally threatened due to the shrinkage of natural habitats and enhanced human activities. On the contrary, a remarkable increase in the population of Sarus cranes was observed during a survey exercised from January to December 2021 in and around the Alwara Lake of district Kaushambi (Uttar Pradesh), India. This systematic survey was conducted to estimate the demographic variations in the population of Sarus cranes from 2013-2021.
