Rare Leucistic Great Cormorant Spotted at Ameenpur Lake, Hyderabad
Why in News?
A rare leucistic Great Cormorant was spotted at Ameenpur Lake near BHEL in Hyderabad on 19 September 2026. The bird had unusually pale feathers, contrasting with the dark plumage of other Great Cormorants in the area. Hyderabad-born Canadian birder Raghuvamsh Chavali photographed the bird and sought independent verification of the unusual sighting.
Great Cormorant: Characteristics and Habitat
The Great Cormorant is a large fish-eating waterbird belonging to the family Phalacrocoracidae. It is commonly found around lakes, rivers, wetlands, estuaries, and coastal waters. The species has dark plumage, a long neck, a hooked bill, and strong diving abilities. Cormorants dive underwater to catch fish and are important components of aquatic food chains. The Great Cormorant is scientifically known as Phalacrocorax carbo. Its presence in wetlands reflects the ecological importance of water bodies that support aquatic organisms and bird diversity.
What is Leucism in Birds?
Leucism is a pigmentation condition that causes reduced coloration in feathers, skin, or scales. It can make a bird appear partially or almost completely white. The degree of discoloration varies between individuals. Leucism differs from albinism. In albinism, melanin production is absent or significantly reduced throughout the body and can affect eye pigmentation. Leucistic birds generally retain normally pigmented eyes, although the exact appearance depends on the underlying condition. The pale Great Cormorant at Ameenpur Lake stood out because it was observed alongside normally dark-plumaged individuals.
Ameenpur Lake and Wetland Biodiversity
Ameenpur Lake is a freshwater lake in Telangana near Hyderabad. It is recognised for its bird diversity and attracts birdwatchers interested in resident and migratory species. The lake was designated as India’s first urban Biodiversity Heritage Site in 2016. Its wetland habitat supports a variety of waterbirds, including cormorants, herons, egrets, and other aquatic species. The sighting highlights the importance of urban and peri-urban wetlands in supporting biodiversity and providing opportunities for ecological observation.
