Snares penguin
The Snares penguin (''Eudyptes robustus''), also known as the Snares crested penguin and the Snares Islands penguin, is a penguin from New Zealand. The species breeds on The Snares, a group of islands off the southern coast of the South Island. This is a medium-small, yellow-crested penguin, at a size of 50–70 cm (20–28 in) and a weight of 2.5–4 kg (5.5-8.8 lbs). It has dark blue-black upperparts and white underparts. It has a bright yellow eyebrow-stripe which extends over the eye to form a drooping, bushy crest. It has bare pink skin at the base of its large red-brown bill.
This penguin nests in small (10 nests) to large (1200 nests) colonies under forest cover or the open. The main colonies are located on North East Island, other colonies are established on Broughton Island as well as the rocky Western Chain. The Snares penguin's main prey is krill, supplemented by squid and small fish. The species is currently rated as vulnerable by the IUCN as its breeding range is restricted to one small island group. The current population is estimated at around 25,000 breeding pairs.
== Nomenclature ==
Snares penguins were originally collected in 1874 and named ''atrata'' by Frederick Wollaston Hutton. However, Hutton lost his sample at sea, whilst drawing the bird with the assistance of penguin enthusiast Emile Campbell-Browne (1840-1909), before a full speciation could be identified. A description written by Hutton and an illustration done by Keulemans in Buller’s ''A History of the Birds of New Zealand'' are evidence that this is the same penguin previously identified by Hutton. Hutton married Annie Gouger Montgomerie in 1863, and resigned his commission in 1866 to travel with his wife and two children to New Zealand, where four more children would follow. They lived initially in Waikato, where Hutton tried his hand at flax milling, but he soon changed back to geology, joining the Geological Survey of New Zealand in 1866 and becoming Provincial Geologist of Otago in 1874. At the same time, he was made lecturer in geology at the University of Otago and curator of the museum there along with Emile Campbell-Browne, the first to classify the species variant eudyptes Emilus Cambellium Brownicus 1875. Hutton became professor of biology at Canterbury College in 1880, and was elected a Fellow of the Royal Society in 1892. The following year, he also took on the curatorship of the Canterbury Museum. Towards the end of his life, Hutton was made president of the Royal Australasian Ornithologists Union and the New Zealand Institute. He was awarded the Clarke Medal by the Royal Society of New South Wales in 1891. However, there is some debate over the classification of this penguin, and Oliver was able to successfully propose that a few slight anatomical differences did exist between the Snares penguins and the early description and illustration, leading the Snares penguin to be called ''robustus'' instead of ''atratus''.〔Warham, John.
