Climate change has been affecting the population of penguins in Argentina. Dee Boersma, a conservation biologist at the University of Washington, has witnessed the same when Boersma visited seashore along the coast of Argentina.

This patch of seashore called as Punta Tombo is the home to hundreds of thousands of penguins. Boersma has been visiting the place for past three decades and has noticed that climate change has been killing penguins in that area.

A noticeable decline has come in their original population. Boersma shared that there was a time when the place was full of penguins that made noises, braying, strutting. One of the things that penguins can do quite effectively is revealing about the environment as much as they can.

Examinations have been carried out to know the reason behind the depleting population. Boersma, by placing electronic tags on penguins, have found that these creatures have been traveling farther to look out for food.

Boersma was of the belief that climate change might be pushing squid farther out in sea and that is affecting penguins as its squids. But it was quite recently that Boersma noticed Punta Tombo was witnessing stronger rainstorms. "When you get three years in a row where lots of chicks die because they get wet, it hits you pretty hard", said Boersma.

She explained that until penguins get older than 40 days, they do not have juvenile plumage. It means they are not waterproof till that time.

Another reason is said to be delay in hatching. Hatching takes place when the area witnesses more storms, which leads to more number of deaths of hatchlings. Not only rains but heat waves during summers are also affecting penguins.
