Crested Penguins (Eudyptes)
"Good Diver"

The Crested Penguins have the greatest number of species (8) as well as the largest population of all genera.
These penguins have a characteristic yellow or orange plume.
All of the crested penguins lay two eggs, a smaller egg followed in 4 to 5 days by a larger egg which hatches first and is most likely to survive

The Western Rockhopper penguin is also known as the American Southern Rockhopper Penguin. They are the smallest of the Eudyptes penguins with an average length of 18 to 23 inches and a weight range of 4.4 to 8 pounds. They are the only species with a black occipital crest. They have a prominent yellow crest and red eyes. They hop over rocks and crevices on land, thus their name. They are loud, noisy, feisty birds quick to attack anything that bothers them. Their global population is approximately 1 million and about two-thirds breed on the Falkland Islands and on islands off the Argentine coast and southern Chile. It's population has decreased by 30% over the last 30 years and is considered vulnerable. Their diet consists mainly of krill and also squid, octopus and fish. Similar to other crested penguins two eggs are laid; a smaller A egg has a mortality rate of 60% to 80% and the larger B egg has a 40% to 60% success rate. They are the only penguin species that will dive into the ocean feet first rather than head first. Rockhopper penguins can swim up to 5.1 miles per hour. Their average lifespan is 10 years, but they can live up to 30 years. Since now classified as separate species, all 3 Rockhopper species are now considered vulnerable.

One of the largest of the Eudyptes penguins with an averaging 27 inches in length and weighing from 7.9 to 15.4 pounds. The spiky, brush like feathers grow from the base of the bill to the top of the head giving them a distinct look. They can also raise and lower these feathers on the crest, which none of the other crested penguins can do. In contrast to the Rockhopper, they only breed mainly on two remote subantarctic islands of New Zealand, the Bounty and Antipodes Islands. There are a few isolated breeding pairs on the Auckland Islands. Until recently they were breeding on Campbell Island but have seemed to disappeared. They can be confused with the Snares and Fiordland crested penguins especially when at sea when the plumes drop down. They feed mainly on shrimp, krill, and squid. There are an estimated 115,000 pairs on Bounty Island and an estimated 110,000 on the Antipodes. The population is vulnerable even though there is very little exposure to humans. There are probably no more than 2 or 3 ship (only of New Zealand registry) visits a year and there is little fishing around the islands as they are protected by the New Zealand Government. Two eggs are laid with a 98% mortality rate of the first and smaller A egg. The second or B egg can be 100% larger then the A egg and the only one to be seriously incubated. Little else is known about these penguins as they are so isolated and have not been studied or observed.
