Surveys of parekareka/ spotted shags by Auckland Council show the importance of 300 remaining nests on predator-free Tarahiki Island and at the eastern end of Waiheke (at Hooks and Anita Bays).
No breeding colonies we found on Coromandel’s offshore islands, where they were reported before 2000, and have disappeared from many parts of the North Island. The birds are vulnerable to set nets, predators and disturbance at breeding sites.
Unique to NZ, spotted shags have distinct crests on their heads, a green patch near the eyes and dappled spots on their back during breeding season, in late winter and spring.
