Great Cormorant
The great cormorant is a sociable species, forming large nesting colonies. It is partly migratory, with some populations remaining in the delta throughout the year, while others migrate to warmer regions in winter. It nests in colonies on islands or in trees, building nests in branches and vegetation. A female lays 3-5 eggs, which she hatches with the male.

Description and how to observe Great Cormorant:
The Great Cormorant is a medium to large waterfowl, about 80-100 cm long with a wingspan of up to 160 cm. Its plumage is predominantly black with metallic greenish-green reflections, and it may sometimes have a whitish patch on the neck. Bright green eyes are a distinctive feature.
To observe them, visit the lakes, canals and open water areas of the Danube Delta. Cormorants can often be seen sitting on the banks or tree trunks, spread-winged to dry themselves, or diving nimbly into the water after fish.
What it feeds on Great Cormorant:
The great cormorant is a specialised predator, feeding mainly on fish. It is an excellent swimmer and can dive to considerable depths to capture prey. It usually favours small to medium-sized fish, but its diet may also include crustaceans or other aquatic life.
Threats:
The great cormorant population faces threats such as habitat destruction, water pollution and conflicts with fishermen who perceive them as competitors. Human activities and climate change can also affect nesting areas and food sources.
Ecological role:
The great cormorant plays an essential role in the delta ecosystem. Through its diet, it contributes to maintaining the balance of fish populations and the overall health of aquatic habitats. It is also a bio-indicator of environmental quality, reflecting the state of the aquatic ecosystem in which it lives.
