Westland 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. Described by Robert Falla in 1946, it is a stocky bird weighing approximately 1,100 grams (39 oz), and is one of the largest of the burrowing petrels. It is a dark blackish-brown colour with black legs and feet. It has a pale yellow bill with a dark tip. This species spends most of its life at sea but returns to land to breed. When at sea, it ranges across areas of the Pacific and Tasman seas around the subtropical convergence and migrates east to South American waters during the non-breeding season. 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.…
