What kind of birds eat plastic?
Parakeet auklets, a small, diving bird that lives in the Northern Pacific near Alaska, shows the highest predisposition toward eating plastic, Wilcox says. Albatross are more prone to eating plastic because they fish by skimming their beaks across the top of the water, and inadvertently take in plastics floating on the surface.
What do petrels eat?
Diet of the Petrel. These seabirds have decently more varied diets than some other seabirds. Outside of the breeding season they feed primarily on fish, squid, octopus, krill, shrimp, and more. Some species feed heavily on a single type of food, like squid. Some of the larger species, like the Giants, also hunt for other creatures and eat carrion.
Why do seabirds eat plastic?
Photograph: Dan Clark/USFWS/AP Seabirds are enticed into eating plastic debris because it smells like their food, according to scientists. The study found that drifting plastic waste accumulates algae and gives off a smell very similar to the krill that many marine birds feed on.
What is a petrel?
The Petrel is actually a group that includes a number of different types of seabirds. Researchers divide these birds into three different families, one of which they share with shearwaters.
What is a Wilson’s storm petrel?
The Wilson’s Storm-Petrel is one of the few birds to breed in the Antarctic. #2. Just the Stats Ma’am The Wilson’s is one of the smaller species in the Hydrobatidae family (averaging only about 7 inches in length) and has a sooty- black plumage with a white rump.

Why are they called Mother Carey’s chickens and Stormy Petrel?
The names “Mother Carey’s Chickens” and “Stormy Petrel” are applied by sailors to the bird known to ornithologists as the Thalasidroma pelagica. Despite its name, it is a tiny creature, scarcely larger than a lark, the very smallest web-footed bird known; of a sooty-black color,…
What are the behavioral and structural groups of storm petrels?
Storm petrels fall into two behavioral and structural groups. Most of the species breeding in the southern oceans are shorter winged, square tailed, long legged, and short toed. With wings spread, they patter over the water, “walking,” and pick up minute marine organisms. An example is Wilson’s petrel ( Oceanites oceanicus ),…
Why are storm petrels nocturnal?
All but one species of Storm Petrel become nocturnal at the nesting sites in order to cut down on their chances of being spotted by predators and leading them back to the eggs or young (Wedge-rumped Storm Petrels being the exception).

Which seabirds are most at risk of being affected by plastic pollution?
“It’s at the edge of the gyre and the edge of the seabird distribution that are at the highest risk,” Wilcox says. Large birds, such as the albatross, eat large amounts of plastics. But that doesn’t mean large birds eat proportionately more plastic.
What kind of plastic is in a bird’s stomach?
Petrels and shearwaters, which live on offshore islands and forage over large areas of sea, also contain large amounts of plastic in their stomachs. Plastic found inside birds includes bags, bottle caps, synthetic fibers from clothing, and tiny rice-sized bits that have been broken down by the sun and waves.
What percentage of seabirds eat plastic?
Plastic trash is found in 90 percent of seabirds. The rate is growing steadily as global production of plastics increases. So much plastic trash is flowing into the oceans that 90 percent of seabirds eat it now and virtually every one will be consuming it by 2050.
What do snow petrels do?
Snow petrels are gregarious birds. During the winter, they disperse to the pack ice, ice floes, and the open sea where flocks are often seen sitting on icebergs.
