why is the humboldt penguin endangered

Also, the penguins could be caught in fishing nets used by commercial fishermen. The penguins are being regularly monitored by BirdLife International and other organizations.In the 18th century, young men who wore hats adorned with feathers were called “macaroni.” When English explorers first saw these penguins, they were reminded of the same hat and hence the name. Humans destroy and remove the guano during nesting season disrupting the penguins. The cement breakwater that connects the islet to the mainland also has given free access to rodents, which feast on the vulnerable eggs and hatchlings of the nesting penguins.A 2012 study found that almost half of all penguin eggs on the island were devoured, primarily by rodents, within the first 12 hours of breeding period. There is a broad black breast band that makes it easy to recognize them.

This Friday is Penguin Awareness Day, which means there’s no better time to learn about the biggest dangers to penguins — and how you can help the ocean’s best-dressed birds thrive for years to come.

This beautiful species, while maintaining its characteristic tuxedo-like appearance, has distinct features that distinguish one from the other. According to the IUCN, a 2015 study noted delayed breeding in warmer conditions among the birds. Due to limited habitat, they are facing a loss of habitat destruction due to devastating human encroachment.

The population has declined rapidly in the last three generations (36 years) mainly because of climate change and competition from commercial fisheries for food. The penguins use guano (feces) to build their nests. You can be assured our editors closely monitor every feedback sent and will take appropriate actions. As commercial fisheries exploit the same locations where the penguins find their prey, the threat of the birds running out of their sardines and anchovies only becomes greater each day. Like other crested penguins, the erect-crested penguins lay two eggs, where the second egg is usually 85% heavier than the first and thus has greater chances of survival. Snares penguins look similar to the other crested species but have bare pink skin at the base of their bills.

"They say it makes the island stink," he explained.Prosecutors say they are investigating the alleged destruction of the penguins' eggs.Part of the blame for the birds' gradual disappearance goes to fishermen's nets that ensnare hundreds of the birds each year.A measure of blame also goes to the El Nino weather phenomenon and the warm water current it carries.The frigid Humboldt current, which gives the penguin species its name, carries the El Nino currents, however, "warm the waters, making it hard for the penguins to find the fish that make up their usual diet," said Guillermo Cubillos of the Santiago National Zoo.If the El Nino warming of the waters occurs during breeding season, many of the eggs or young die of cold and hunger, because their parents are delayed or even fail to return with food.Rats also are seen as a major culprit. The Humboldt Penguin National Reserve is situated 600km (372.8 miles) north of Santiago, Chile. "Alejandro Simeone, director of the Department of Ecology and "A multitude of factors threaten a species that is highly diminished relative to what once existed," Simeone said.The beginning of their demise dates back to 1978, when the island, which is also a nature sanctuary, was joined to the mainland by a cement fill-in—a breakwater designed to protect the yachts of millionaire sailing enthusiasts.It created in effect a 150-meter (500-foot) bridge connecting the mainland to the island, and local residents say they have seen the detrimental impact of its construction on animal and plant life.Yachters have been accused of trying to rid the region of the birds, and video footage has surfaced showing some deliberately—and illegally—destroying penguin eggs to prevent new broods.Rojas said the yachters don't like the excrement left behind by the birds.
