This puffin means business. =) Two-for-one puffins in this photo with the Tufted Puffin looking at the camera and the Horned Puffin in the background. This photo was taken at the Alaska Sealife Center in Seward. Ironically, the Alaska Sealife Center was funded in part by the settlement from the Exxon Valdez oil spill. Interesting.

Another fantastic horned puffin photo from Constantine D. Definitely worth seeing up close.

Horned Puffin (Fratercula corniculata)

Originally uploaded by ConstantineD

The Horned Puffin (Fratercula corniculata) is an auk, similar in appearance to the Atlantic Puffin; this bird’s bill is yellow at the base and red at the tip. It is a pelagic seabird that feeds primarily by diving for fish. It nests in colonies, often with other auks.

The yellow bill plate grows before the breeding season and is shed later. They have a small fleshy black “horn” above their eyes. They have a white face with a dark line extending from the back of the eye and red feet.

This species breeds on rocky islands off the coasts of Siberia, Alaska and British Columbia, in burrows, in rocky cavities or among rocks. It winters far out to sea. Feeding areas are usually located fairly far offshore from the nest. There is usually one chick and both parents feed the young.

Horned Puffins will return from hunting with several small fish in their beaks. They also eat squid and crustaceans.

The population of these birds has declined due to the introduction of rats onto some islands used for nesting.

Puffin Predators

Sunday, April 5th, 2009

Predators are a natural part of life. And while uber adorable puffins also have predators. Each puffin has its own set of predators.

What are the puffin predators? What preys on Puffins?

Predators of the Atlantic puffin include people; gulls and skuas including the Great Black-backed Gull, the Great Skua, the Herring Gull amongst others; rats; cats; dogs; and foxes. Puffins are also vulnerable to pollution, fishing nets, declining fish populations, and global warming.

Predators of the Tufted Puffins include people, unfortunately. Tufted Puffins have three major predators the Snowy Owl, Bald Eagles and Arctic Foxes. They are also vulnerable due to decreasing fish population, ocean pollution and oil spills.

Predators of the Horned Puffin include people as well. Horned Puffins also are preyed upon by gulls, foxes, larger predatory birds and rats. Traffic, oil spills, ocean pollution, over-fishing and the resulting declining fish population as well as global warming are also affecting their survival rate.

Puffins do have some unique abilities to protect themselves from predators. Their bill is very hard and colorful to warn other animals of the pain it can cause. For predators flying above puffins blend into the water while swimming which they do more often than not. This is due to their black backs, heads and sides. Underwater, the puffin also has an advantage. The underwater predators are fooled by the puffin’s white bellies mistaking them for glimpses of the sun.

Rhinoceros Auklet

The Rhinoceros Auklet, Cerorhinca monocerata, is a seabird considered, despite its name, a close relative of the puffins. It is the only living species of the genus Cerorhinca. Given its close relationship with the puffins the common name Rhinoceros Puffin has been proposed for the species.

It ranges widely across the North Pacific feeding on small fish and nesting in seabird colonies. Its name is derived from a horn-like extension of the beak. This horn is only present in breeding adults, and like the elaborate sheath on the bill of puffins is shed every year.

The Rhinoceros Auklet (also known as the Rhino Auklet, Horn-billed Puffin, or Unicorn Puffin), is a medium sized auk with a large, strong, orange/brown bill (with the ‘horn’ protruding from it). The plumage is dark on top, paler below, and the breeding adults, both male and females possess white plumes above the eyes and behind the bill. Males are slightly larger than females (about 10% in mass).

The Rhinoceros Auklet is a North Pacific auk that breeds from California (the Channel Islands) to the Aleutian Islands in Alaska in North America; and Hokkaidō and Honshū, Japan, as well as North Korea and Sakhalin Island in Asia. It winters both in offshore and inshore waters, exhibiting some migration.

The Rhinoceros Auklet nests in burrows dug into the soil or in natural caves and cavities between 1 to 5 m deep. It prefers nesting sites on slight inclines to aid take-off (as it is a poor flier). A single egg is incubated by both parents for 45 days, the semiprecocial chick is then fed each night with a bill full of fish (in the manner of puffins) for 50 days. The nocturnal behaviour is believed to be a response to predation and kleptoparasitism by gulls.

At sea Rhinoceros Auklets feed on fish, with some krill and squid taken also. They feed inshore during the breeding season in the midwater. To catch their prey, they dive to as deep as 57 meters (187 ft) for as long as 148 seconds.

Evolution and prehistoric species

The genus Cerorhinca evolved in the North Pacific, apparently in the mid-late Miocene. Although today only one species remains, it used to be much more diverse, both in number of species and in distribution; fossils have been found as far south as Baja California. Known prehistoric species are:

* Dubious Auklet, Cerorhinca dubia (Late Miocene of San Barbara County, USA)
* Cerorhinca minor (Late Miocene/Early Pliocene of Cedros Island, Mexico)
* Cerorhinca reai (San Diego Late Pliocene, SW USA)

(Above information from Wikipedia)…

If you want to see the Rhinoceros Auklet on webcam, you can see it at the California State Parks website. Click here, then scroll down — on the left side click on “HD Sealcam”. This is a camera set up to record the nighttime species. The Auklet takes care of its young and eggs at night. They burrow at night. =)

Rhinoceros Auklet, Oregon Coast Aquarium, Newport, OR

The Rhinoceros Auklet is not very well known but it is considered, by some, to be part of the puffin family. They are debating on whether they should rename it the Rhinoceros Puffin since it is so closely related to the puffin family.

Is a puffin a puffin by any other name?

Apparently. This puffin has many names: Cerorhinca monocerata, the Rhino Auklet, the Horn-billed Puffin or the Unicorn Puffin. (I think I prefer the latter but I’ll try to use all of them to get us accustomed to them all.) This cute little bird gets its name because of the horn-like extension on its beak but they only get this fancy beak when they are ready to breed. And it, like all puffin’s bills, sheds it sheath every year.

The Unicorn Puffin lives in colonies on the ocean shores much like the three other puffins. They prefer the North Pacific Ocean breading all along it from California to the Aleutian Islands in Alaska. They can also be found in Japan, North Korea and Sakhalin Island in Asia. They spend their winters in the water and their summers breeding near the water.

They like to eat small fish, krill and squid. According to Wikipedia,

“they feed inshore during the breeding season in the midwater. To catch their prey, they dive to as deep as 57 meters (187 ft) for as long as 148 seconds.” Interesting swimmer fishing.

The Cerorhincas evolved in the Miocene period, some 23.03 to 5.33 million years ago. That is a long time. This is an old species. There once was at least 3 other varieties of the cerorhincas (the Dubious Auklet — wonder what he was dubious about, perhaps the fishers that made him disappear?, the Cerorhinca minor and the Cerorhinca reai) but they have all disappeared now and only the Rhino Auk are left.

But it still has the other 3 puffins out there. I hope we can ensure they all survive for a very, very, very long time.

INTERESTING FACT
It was onced believed that a Puffin was a fish as well as a bird. People thought it was born from rotting piece of wood floating in the sea, instead of hatching out from an egg as we know it does today.
