Great Cormorant in Singapore

The Great Cormorant (Phalacrocorax carbo) is a very common and widespread member of the cormorant family of seabirds. It is found on every continent except South America and Antarctica.

The species breeds along rocky maritime coasts, nesting on cliff ledges or rocky islands free of predators, and feeding in sheltered inshore waters.

In the past, Great Cormorants migrate to Peninsular Malaysia an possibly Singapore, but now only rare vagrants occur in Malaysia. In Singapore, there is/was however a population of Great Cormorants, escapees or free ranging birds from the bird park. They have been found residing at Kranji Dam, Sungei Mandai and Mandai mudflats near the estuary of the river. In 2004, there was a record of 11 birds seen at Kranji Dam1. Breeding is suspected as there were juvenile birds along with the adults.
