Huia (Heteralocha acutirostris)
New Zealand status: Endemic
Conservation status: Extinct
Huia were unique birds; sexually dimorphic due to the different bill shape and known to hunt cooperatively close to the forest floor in search of invertebrates and fruit.
Rats, cats, stoats and ferrets are attributed as the primary cause of this extinction, and would have found huia easy prey as it was often referred to as “ecologically naive”. Like so many endemic species in NZ, it had no evolutionary experience in co-existing with mammals and was not distressed by their presence. Genetic studies indicate a population of somewhere between 34,000 to 89,000 birds existed historically (in the North Island only) and a deadly cocktail or these predators and human hunting witnessed the loss of this entire population in a relatively short time.
