About Kerala’s red list-
- The Kerala Bird Monitoring Collective led by Kerala Agricultural University and the Bird Count India will conduct the regional red list assessment.
- Once it gets ready, Kerala will be the first State to have a region-specific red list of birds.
- Assessment will be done on the basis of the International Union for Conservation of Nature (IUCN) guidelines.
- The IUCN guidelines for preparing the red list have five main criteria.
- The population size reduction measured over 10 years or three generations is one of the major guidelines.
- Geographic range on the basis of extent of occurrence or area of occupancy is another.
- Small population size and decline.
- Very small or restricted population.
- Quantitative analysis indicating the probability of extinction in the wild are the other criteria.
- According to the global IUCN red list, Kerala has 64 threatened species of birds. In that, Red-headed vulture and White-rumped vulture are critically endangered and Steppe Eagle, Banasura Chilappan and Nilgirl Chilappan are endangered and 11 species are vulnerable.
- The Kerala Bird Monitoring Collective is planning to prepare the red list for the State in a year. It will be a decentralised process like how the Kerala Bird Atlas was prepared
Kerala Bird Atlas (KBA)-
- Conducted as a citizen science-driven exercise, a survey for KBA was jointly conducted by the Kerala Agriculture University, Bird Count India involving 1000 volunteers and supported by the Kerala Forest Department.
- It is the first-of-its-kind state-level bird atlas in India (Mysore city Bird Atlas is on from 2014).
- The Atlas, prepared between 2015 and 2020, provides solid baseline data about distribution and abundance of various bird species in the State.
- The Kerala Bird Atlas accounts for nearly three lakh records of 361 species, including 94 very rare species, 103 rare species, 110 common species, 44 very common species, and 10 most abundant species.
- According to the atlas, most of the endemics are concentrated in the Western Ghats while the threatened species are cited mostly along the coast
