Snares Penguins, Eudyptes robustus
Taxonomy Animalia Chordata Aves Sphenisciformes Spheniscidae Eudyptes robustus
Description & Behavior
Snares penguins, Eudyptes robustus (Oliver, 1953), aka Snares crested penguins or Snares Islands penguins, are crested penguins that stand 40 cm tall and weigh about 3 kg. They are often confused with Fiordland crested penguins, however their patch of skin at the base of their bills helps distinguish them from the Fiordlands. Snares penguins have a black head, throat and back with white bellies. Their yellow crest begins at the base of their bills and extends to their eyes and then drops behind their heads.
World Range & Habitat
Snares penguins, Eudyptes robustus, are named for the Snares Islands where they breed. Snares penguins nest in the islands' vegetation in dense colonies, moving to "fresh" sites while the vegetation of old sites recovers from the breeding and nesting activities.
Feeding Behavior (Ecology)
Snares penguins, Eudyptes robustus, reach sexual maturity at about 6 years of age and begin the breeding season in August when the males return to the colony, followed by the females a short time later. Females lay 2 eggs in late September; the 2nd is often larger and the egg that survives incubation. Parents share brooding the newly hatched chick for about 3 weeks, with the male guarding while the female forages and feeds. This phase is followed by a period when both parents forage and feed while the chick forms crèches with other chicks nearby. Chicks fledge around 11 weeks.
Conservation Status & Comments
Snares penguins, Eudyptes robustus, are listed as Vulnerable D2 (VU) on the IUCN Red List of Threatened Species:
A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable (see Section V), and it is therefore considered to be facing a high risk of extinction in the wild.

Help Protect and Restore Ocean Life
Help us protect and restore marine life by supporting our various online community-centered marine conservation projects that are effectively sharing the wonders of the ocean with millions each year around the world, raising a balanced awareness of the increasingly troubling and often very complex marine conservation issues that affect marine life and ourselves directly, providing support to marine conservation groups on the frontlines that are making real differences today, and the scientists, teachers and students involved in the marine life sciences. Join us today or show your support with a monthly donation.
With your support, most marine life and their ocean habitats can be protected, if not restored to their former natural levels of biodiversity. We sincerely thank our thousands of members, donors and sponsors, who have decided to get involved and support the MarineBio Conservation Society.
