Kolleru Lake Sees Massive Bird Revival

Kolleru Lake, a major Indian freshwater wetland and Ramsar site, is demonstrating a remarkable resurgence in bird populations. Current estimates indicate between 45 lakh and 60 lakh birds inhabiting the area and its surroundings, a significant increase reflecting improved ecological conditions.

The wetland is supporting 30 to 40 key bird species, crucial indicators of wetland health, with many observed in higher numbers than previously recorded. The notable return of flamingos, a species sensitive to environmental changes, signals a regaining of balance within the ecosystem after years of degradation. These birds are sharing habitats with various migratory waterfowls, reinforcing Kolleru's status as a vital wintering ground.

This revival is largely attributed to the removal of encroachments within the lake, which has facilitated the return of rich biodiversity. Migratory birds, traveling from as far as Siberia, Russia, and Europe, are utilizing Kolleru as a critical feeding and resting area on their international routes. An ongoing bird census, employing scientific mapping and grid-based surveys, is meticulously documenting these populations across the main lake and newly occupied supplementary habitats.
