DULIAJAN, May 14 - Amidst the negativity during the COVID-19 outbreak, a photograph of a rare white crow has led to curiosity among nature lovers.
Nagen Baruah, a photographer of the Public Affairs department of Oil India Ltd, captured in his camera a photograph of the rare white crow recently near OIL�s field headquarters at Duliajan. The white crow was seen with other crows at the time when Baruah captured the photo.
Asked about details of the bird, environment activist and nature organisation Nature�s Beckon coordinator Soumyadeep Datta called it a rare case. Datta identified the bird as a common crow (Corvus splendens). He said he had observed partial white feathers of crows earlier, but had never seen a completely white crow. He said that the main cause of the white colour of the bird remains unknown, and it shall be interesting to find out if there is any other white crow in Duliajan.
The bird will open new doors of biological studies, he added.
According to scientific journals, a white crow can have all white feathers and pink feet, legs and bill. These are features of albino birds.
The Cornell Lab of Ornithology explains albinism as a genetic mutation that prevents the production of melanin in the body. Albinistic birds have pink eyes because without melanin in the body, the only colour in the eyes comes from the blood vessels behind the eyes. Another genetic defect is leucism, which is a form of partial albinism, and affects the deposit of melanin in feathers.
