A communications professional, Tushar Kaushik, observed a grey-headed eagle being mobbed by crows at Sukhna Lake on December 29, 2025. Kaushik, who has a keen interest in bird behavior, captured photographs of the raptor before it disappeared into the fog. The eagle, a winter visitor, was previously sighted in October by Ranjeet Singh 'Sagar', a dismissed forest chowkidar known for his knowledge of local wildlife.
