Phalacrocorax sulcirirostris (Brandt, 1837)

Common Name: 
Little Black Cormorant
Distribution: 

Ranges from New Zealand's North Island, throughout Australia, New Guinea, Indonesia (but not Sumatra) and the Malay Peninsula. 

Ecological Notes: 

Typically observed in wetlands and sheltered coastal waters, especially lakes, reservoirs, rivers, bays and inlets. The Little Black Cormorant feeds primarily on fish, and eats a higher proportion of fish than the frequently co-occurring Little Pied Cormorant, which eats more crustaceans.

Additional Notes: 

Forms flocks when chasing prey, individuals leap frogging those in front. Often observed in small groups drying wings on fallen or dead trees over water. Walks with a waddling gait, but flies with strong wing beats.
