Westland Black Petrel

The Westland petrel (Procellaria westlandica), (Māori: tāiko), also known as the Westland black petrel, is a moderately large seabird in the petrel family Procellariidae, that is endemic to New Zealand.

They feed on fish, squid and crustaceans. This species is also known to be an opportunistic feeder, scavenging fish waste discarded by hoki fishers.
The only known breeding colonies of the Westland petrel are in New Zealand, in a small area of forest-covered coastal foothills between Barrytown and Punakaiki on the South Island's West Coast. The birds nest in burrows excavated into hillsides and slopes, and exhibit natal philopatry, that is they return to their natal colony to breed. The...
