Atlantic puffin with fish. Like many auks, puffins eat both fish and zooplankton but feed their chicks primarily with small marine fish several times a day. The puffins are distinct in their ability to hold several (sometimes over a dozen) small fish at a time, crosswise in their bill, rather than regurgitating swallowed fish.
Sometimes, a bird such as an Arctic skua or blackback gull can cause a puffin arriving with a beak full of fish to drop all the fish the puffin was holding in its mouth. The puffin's striking appearance, large, colourful bill, waddling gait, and behaviour have given rise to nicknames such as "clown of the sea" or "sea parrot".
The chicks have a less varied diet, feeding mainly on sandeel or capelin from near the coast. These fish are distributed by the parents two to six times per day. [18] Unlike many other seabirds, which employ regurgitation to feed their young, horned puffins feed their chicks whole fish directly from the bill. [27]
Tufted puffins are around 35 cm (14 in) in length with a similar wingspan and weigh about three-quarters of a kilogram (1.6 lbs), making them the largest of all the puffins. Birds from the western Pacific population are somewhat larger than those from the eastern Pacific, and male birds tend to be slightly larger than females.
The fish range in size from about 3.83 inches to about 4.86 inches long, the study said. They were collected from between approximately 630 feet underwater to about 985 feet underwater.
Unlike mammals, the red blood cells of fish have DNA, and can become infected with viruses. The fish develop pale gills, and may swim close to the water surface, gulping for air. However, the disease can also develop without the fish showing any external signs of illness, the fish maintain a normal appetite, and then they suddenly die.
