As a result, puffins look like soft, round balls. This effect becomes even more dramatic when two puffins fight. In an attempt to look bigger and more intimidating, puffins raise their feathers.
While this might make them look scary to other puffins, it just makes them cuter to humans. Puffins mainly eat fish, although they will eat crustaceans if need be. Like most sea birds, puffins hunt for their prey by diving. They can stay underwater for up to a minute searching for fish, but usually only spend seconds in the water at a time. Puffins are able to carry an impressive number of fish in their beaks at once - they usually catch around 10 or so per hunt, but have been known to carry more.
According to Project Puffin, the record for fish held at once was A plethora of puffins. A Horned Puffin.
The easiest way to tell puffins apart is by their beaks. Download the Planet Puffin Podcast. Why the albatross is master of the skies. A cat's guide to breaking the Internet View A cat's guide to breaking the Internet.

Puffins live for about 20 years in the wild. The oldest known puffin lived to be 36 years old. How many puffins are there today? Estimates vary from 3 to 6 million worldwide. Do puffins have any predators? Rhinoceros Auklets are nocturnal, making it difficult for scientists to observe their natural behaviour patterns.
Nobody really knows why the Rhinoceros Auklets both male and female have the horn on their beaks. The Rhinoceros Auklet is the last existing member of its genus, Cerorhinca. Related cruises. They dig dog-like, shoveling dirt out behind themselves. Most burrows are 2 to 3 feet long 70 to cm , which is as long as the arm length of an adult human.
At the back of the burrow the parents build a soft nest of feathers and grass where they incubate the egg. The burrows often have a toilet area at the first bend. As it matures, the toilet is moved closer to the burrow entrance, helping to keep the chick clean. Puffins typically lay 1 egg per year. They usually keep the same mate every season and use the same burrow as in previous years.
The male and female share the duties of incubating the egg and rearing the chick. Puffin chicks need a lot of care and need several feedings per day.
Sometimes the puffin parents will leave the egg by itself early in the incubation stages, but as the hatch date nears, they tend to sit on the egg for longer periods of time. The egg needs approximately 40 days or so of incubation before it will hatch.
Puffins often live 20 years or more. The oldest known puffin lived to be 36 years. Maximum age is difficult to determine because while researchers are able to band birds, puffins abrade these bands by nesting among boulders as well as spending the majority of their lives in the open ocean, which causes leg bands to corrode over time. Both these mechanisms cause bands to become too worn to read. Note that Puffins sometimes have TWO bands on their legs. The one with the long string of numbers is issued by the US Fish and Wildlife Service, and that number is unique to that individual bird.
But, because the longer numbers are sometimes difficult to read in the field, Project Puffin creates a special "Field Readable Band" which is only used for Maine Coast Projects. This band has fewer letters and numbers, and can be easier to read by Project Puffin staff members observing birds through spotting scopes, and easier to see if the bird is captured on camera.
During winter, the bills and feet of puffins fade to dull shades of their summer colors. Every spring their beaks and feet turn a colorful orange in preparation for the breeding season.
The beaks and feet of puffins become brightly colored and the beak increases in size as the bird matures. Puffins use body movements to communicate in a variety of situations. In mating and courtship the puffins will pair up before they come onto the island from the ocean.
Once they are on land, the pair may perform billing, a behavior where puffins rub their beaks together. This display often draws a crowd of puffins to share in the excitement. An aggressive encounter between two puffins often begins by gaping. This involves a puffin puffing up their body to look bigger and opening their wings and beak slightly. The wider the beak is opened the more upset the puffin. The puffin may also stomp its foot in place to show its displeasure.
The bright colors of the feet and beak help illustrate these motions. If the aggressive encounter escalates into a full-scale brawl the puffins will lock beaks. They will then attempt to topple each other in a wrestling match by using their feet and wings in a flurry of action. A fight may gather a crowd of 10 or more puffin spectators. The combatants may become so involved in the fight they end up rolling off their rocky perch. A puffin also communicates information in its manner of walking.
The puffins that are guarding burrows usually assume a pelican walk position that has the puffin stand stiffly erect with its beak next to its body and using slow exaggerated foot movements.
This makes the puffin look like a soldier on guard duty, which is just what it is doing by guarding the burrow. After a puffin lands it will assume a post-landing position.
This is a site ownership display that serves as a mild threat to nearby puffins. This position consists of landing with one foot in front of the other foot, with wings outspread and head angled down.
This is a sign of non-hostility that relieves tension when landing in a group of puffins. This permits large numbers of puffins to congregate together, which has important social and predator defense benefits.
