Description : The Great Cormorant is a large waterbird with a long bill (adult bird length approximately 80 cm, wing 34 cm, bill 6.5 cm, tarsus 6.5 cm, tail 15 cm). It has silky white feathers on the head, crest and neck. Its facial skin and throat are white and gular pouch is bright yellow. It breeds in September-February. The great cormorant forms colonies near wetlands, rivers, and sheltered inshore waters. It builds nests from sticks in trees, cliffs, or on predator-free rocky islands. Each year, pairs return to the same nesting site. The cormorant lays a clutch of three to five pale blue or green eggs, which are incubated for about 28 to 31 days. It feeds on fish, primarily wrasses, obtained through diving. The bird's foraging dives last around 28 seconds, reaching depths of up to 5.8 meters. The cormorant's hearing is adapted for underwater use but has reduced sensitivity in the air. In some areas, overwintering cormorants have been associated with significant fish losses.
