Kerala Bird Atlas is a citizen science project to understand the distribution, abundance, seasonal occurrence of birds of an entire Indian state for the first time. The entire state of Kerala was systematically surveyed twice a year during 2015–2020 and over 0.3 million records of 380 species from 25,000 checklists were aggregated. After eliminating nocturnal and pelagic species, in total 361 species were analyzed to get results.
