NEW  ZEALAND  ECOLOGY

WATTLEBIRDS

Three unique wattlebirds with an ancient lineage, the extinct huia, and extant kokako and saddleback, make up the total Callaeidae family. The family is endemic to New Zealand.  Five species in three genera are not closely related to Australian wattlebirds or any other species in the world. The New Zealand wattlebirds are thought to have arrived as wind blown migrants during the Paleocene 60 million years ago, when they were probably able to fly better than they do today.

Wattlebirds migrated at about the same time as two other distinctive families of New Zealand land birds, wrens and native thrushes.  These three families are not found in any other part of the world. Most of them developed ground feeding habits, and in some cases various degrees of flightlessness in a predator-free ecosystem.  Extinctions occurred after human settlement when mammals were introduced and habitat was destroyed by fire or converted to pasture.


Huia  Heteralocha acutirostris

The huia was one of the biggest losses to New Zealand's unique avifauna.  It became extinct in 1907 after extensive hunting for European museum collections, and for its tail feathers, which were in great demand due to an international fashion of wearing them in hats. The male and female were so sexually dimorphic with different straight and curved beak forms, they were at first thought to be separate species. The huia was the only species in the Heteralocha genus and one of only 5 species in the Callaeidae family which is endemic to New Zealand.  See more

North Island saddleback
Philesturnus rufusater
South Island saddleback
Philesturnus carunculatus

The North Island saddleback is the strongest survivor of New Zealand's wattlebirds, mainly because it is now only on offshore islands that are free of predators, and five mainland fenced sanctuaries. Until a century ago, both the North and South Island species were common throughout podocarp forests on both mainland islands.  South Island saddlebacks are now limited to Big South Cape, Pukeweka, and Soloman Islands off Stewart Island.  See more

Saddleback

North Island kokako  Callaeas wilsoni
South Island kokako  Callaeas cinerea

The North Island kokako is highly endangered - the only naturally remaining wattlebird on the mainland.  Small populations are intensely managed through captive breeding, trans-location and predator control in 'mainland island' or fenced sanctuaries. The South Island kokako hasn't been seen for three decades and is assumed to be extinct. Kokako eat fruit from 12 trees, but are not a significant seed disperser because of their limited range. Only kokako and kereru can swallow the largest native taraire fruit.  See more
