Study Shows Migratory Bird Count Falls Due to Urbanization

The number of migratory birds that once frequented Bengaluru’s lakes is fast reducing due to rapid urbanization and change of the ecosystem around the water bodies, according to a study. Conducted with the help of data collected by Bengalureans and uploaded to the eBird portal, the study has found the number of migratory birds such as northern pintail, green sandpiper and wood sandpiper is going down in Bengaluru, while that of lake-dependent resident birds has increased in the past five years. eBird is an online database where citizens, researchers and bird enthusiasts upload their bird observations. The researchers said urbanization has a species-specific impact on lake-dependent birds in Bengaluru, with specific groups faring better than others.
