What is the origin of the name 'Humboldt Penguin'?

The explorer Alexander von Humboldt discovered a current off the coast of Peru, which he named the Humboldt Current. It is believed that he also discovered penguins along the coast influenced by this current, leading to the name Humboldt Penguin.

Why do Humboldt Penguins live there?

Humboldt Penguins primarily inhabit areas along the coasts of Chile and Peru where the Humboldt Current flows, such as from Foca Island in Peru to Algarrobo in Chile, extending occasionally as far as Chiloe Island. They prefer these relatively dry regions, though the exact reasons are unclear. However, it could be because their prey, such as anchovies, are abundant around these islands.

What do Humboldt Penguins eat?

They dive in the sea to eat small fish such as anchovies. Chicks are fed regurgitated fish by their parents.

Why are there so many Humboldt Penguins kept in Japan?

The reason is related to the climatic similarities between their main habitats in Chile and Peru and Japan. Let's compare the climates of Chile and Japan. Note that the seasons in Chile are the opposite of those in Japan, with summer from December to February and winter from June to August. The highest summer temperature in Chile is 29 degrees Celsius, and the highest winter temperature is 14 degrees. In Japan, the highest summer temperature can reach 40 degrees, and the highest winter temperature is also around 14 degrees. Excluding the recent severe summers, the climates of the two countries are quite similar, which, coupled with Japan's advanced breeding technology, has led to the increase in the number of Humboldt Penguins being kept.

Does the Humboldt Penguin have any natural predators?

The natural enemies of Humboldt Penguins include stray cats and foxes, but perhaps the greatest threat comes from humans. Humboldt Penguins are currently listed as 'Vulnerable' by the IUCN due to factors such as rising sea temperatures from global warming, fishing industry accidents, and the invasion of non-native species like rats. The El Niño phenomenon can lead to a decrease in plankton, which diminishes the fish population that the penguins rely on for food, potentially leading to starvation. Also, the increased ability of non-native species to move around has led to more attacks on eggs and chicks. Various conservation efforts are ongoing, not only locally in Chile but globally, and understanding the current situation can also be a way for us to help.

What is the lifespan of Humboldt Penguins?

In the harsh conditions of the wild, Humboldt Penguins can live up to about 30 years.
