The Kerala Bird Atlas (KBA), the first-of-its-kind state-level bird atlas in India, has created solid baseline data about the distribution and abundance of various bird species across all major habitats giving an impetus for futuristic studies.
About Kerala Bird Atlas (KBA)
- KBA was prepared based on systematic surveys held twice over 60 days a year during the wet (July to September) and dry (January to March) seasons between 2015 and 2020.
- KBA accounted 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. “
Credit: Special Arrangement (TH) - KBA offers authentic, consistent and comparable data through random sampling from the geographical terrain split into nearly 4000 grids.
- It is arguably Asia’s largest bird atlas in terms of geographical extent, sampling effort and species coverage derived from the aggregation of 25,000 checklists.
- Most of the endemics were concentrated in the Western Ghats while the threatened species were mostly along the coasts. The KBA is considered to be a valuable resource for testing various ecological hypotheses and suggesting science-backed conservation measures.
- Among the species, White-cheeked Barbet and House Crow with 13,855 records 12,380 occurrence records topped the chart compared to 20 other species, which had just single occurrence records.
- The survey, however, ignored the very short duration passage of migrant species like Eurasian Cuckoo, Amur Falcon etc.
