Yellow-eyed Penguin hoiho

New Zealand Yellow-eyed Penguins, hoiho, are a rare, threatened, and nationally endangered species. Although I am unsure of any updates to these numbers, estimates put the breeding pairs figure at approximately 1,700, over 600 pairs of which are on the South Island, and nearly 200 pairs on Rakiura/Stewart Island.

Richdale's penguin M. a. richdalei, is an extinct subspecies that was only on the Chatham Islands. Waitaha penguins are sometimes thought of as a Yellow-eyed Penguin subspecies.

Yellow-eyed Penguin Habitat and Distribution

On the South Island, Yellow-eyed Penguins can be found on Banks Peninsula, the Otago Peninsula, North Otago, the Catlins on the south coast, in the South-east of the South Island.

Other islands where hoiho are found and breed are Stewart Island/Rakiura and surrounding islands, the Auckland Islands, Campbell Island, and Codfish Island/Whenua Hou.

A few have been seen on the North Island in the Bay of Plenty region, the Chatham Islands, and Snares Islands.

Breeding Sites

Yellow-eyed Penguins will breed on partially exposed cliffs, on hill pasture grassland, coastal scrub and forest where there is some wind protection.

Description and Identification

Yellow eyed penguins are easy to identify as they are distinct, with no other species of similarity in size and colour.

Although the male is larger, the male and female penguins look the same, with distinctive yellow eyes and colourful feather patterns around the head and eyes, and colourful brown and cream long bill. Juvenile birds have paler eye and feather colours on the head and neck. Feet are pink, the front and under wing areas are white, the tail and back are a bluey colour.

See the photos on this page to appreciate the distinctive hoiho colouring.

Yellow-eyed Penguin Diet

Hoiho will forage from two to twenty-five kilometres offshore, at diving depths of 40-120 metres to feed on species of fish such as red cod, blue cod, ahuru, opalfish, silversides and sprat, along with crustaceans and cephalopods.

Survival and Conservation of Yellow-eyed Penguins

On Land

The main threats to survival of Yellow-eyed Penguins on land are humans, predators, disease, loss of habitat, temperature extremes causing hypothermia or heat stress.

Penguin chicks survival is threatened by predators introduced by humans such as dogs, cats, stoats, and ferrets.

Adult penguin survival is threatened by predatory dogs owned by humans. From that I determine that humans are the biggest threat to penguins due to the animals they have introduced to New Zealand, animals they currently own, or the predators that humans have let free to roam the country, accidentally or on purpose, since they arrived on the islands.

Off Shore

In the waters and open seas the main threats to penguin survival from other wildlife is from seals and sea lions, sharks and barracuda.

And of course, back to the threat from humans through fishing tackle, plastic rubbish, boating, and pollution.

There doesn’t appear to be any current evidence of an impact from recreational or commercial fishing on competing fish stocks that penguins rely on.

Disease

There has been more than one recorded significant number of deaths of penguins in New Zealand. One major die off in 1990 and another one more recently during a breeding season where a disease named as diphtheritic stomatitis infected chicks on land.

Human Disturbance

In locations where penguin viewing tourism is regulated and successfully managed the impact on the successful breeding abilities of the penguins is said to be very little.

However, as these wonderful and rare penguins have become somewhat of a big tourist attraction, in some instances visitor numbers and disturbance has been detrimental to their breeding and survival in locations where there is no regulation or management of visitors.

The Department of Conservation (DOC), along with Yellow-eyed Penguin Trust, landowners and communities, manage habitat restoration and protection, and predator control where possible.

Where visitor access is not regulated, information signs and hides to view penguins from without disturbing them have been installed. This attempts to ensure the penguins can breed relatively undisturbed. Educating visitors through information boards and roping off areas of beaches etc. goes some way to achieving a balance of conservation of this species while still permitting people to see the unique wildlife.
