Galapagos Penguins Matt Hamilton Period 3 4/27/12
What is a Galapagos Penguin? The Galapagos Penguin is a very cool creature. The average Galapagos Penguin is 49 centimetres (19 in) long and 2.5 kilograms (5.5 lb) in weight. They have a black head with a white border running from behind the eye, around the black ear-coverts and chin, to join on the throat. They have blackish-grey upperparts and whitish underparts, with two black bands across the breast, the lower band extending down the flanks to the thigh. Juveniles differ in having a wholly dark head, greyer on side and chin, and no breast-band. The female penguins are smaller than the males, but are otherwise quite similar. Adult Juvenile There are 17 species of penguins, and the Galapagos Penguin is the third smallest species of penguin. Its an endangered species, with only left.
Whats for Lunch? All Galapagos penguins are carnivores. They eat krill, which are microscopic shrimp, small crustaceans, squid, and various fish species. Krill Squid Crustaceans Fishes
A Typical Penguin Day Galapagos penguins spend most of their day trying to stay cool, find food, and take care of their chick when they have one. They always stay near the archipelago, close to their breeding grounds. The penguins stay by the cool waters, both to lower their body temperature and to find food. Once the sun does down, they stop hunting and return to land. Staying cool and catching lunch Loyal creatures, they mate for life, and usually lay one to two eggs, up to three times a year. If both hatch, the parents only raise one, which seems a bit harsh, especially if youre the second baby.
How does where the Galapagos Penguin live influence how it lives? The Galapagos Islands are a part of Ecuador. The Galapagos Islands are on the left. Penguins live in the red areas.
Survival Galapagos penguins are the only penguins that can live north of the Equator. Even though its a hot climate, they keep from getting too hot by the cool waters of the Cromwell Current, which flows by the islands. Galapagos currents The current cools the penguins and carries abundant food. While theyre trying to stay cool and full, they have to watch out for crabs, owls, snakes, hawks, sharks, fur seals and sea lions.
Adaptations Being so close to the Equator, the biggest problem the penguins have is staying cool in the hot sun. Besides cooling off in the water, they stretch out their flippers to let heat escape and lean forward to keep the sun off their feet, because their feet lose a lot of heat. They also pant, using evaporation to cool them down. They also dont breed during El Nino, because it heats the water and makes the amount of food in the water go down, and they only breed when theres a lot of food available. Eggs and chicks are protected from the sun by keeping them in crevices in rocks. I think the only reason they can survive so close to the Equator is because of the Cromwell Current. This is the only place where this combination of hot land and cold currents exist.
How Have People Interacted with the Galapagos Penguin and its Environment in a Positive Way? Penguin Condos: Since one of the problems the penguins have is having their habitats destroyed, in September, 2010, a team of people from the University of Washington built 120 artificial nests for their young, away from predators. They used local lava so the nests felt natural. Penguin Eggs
More Positive Ways to Help the Penguins Habitat Preservation: You cant build penguin nests if theres no land to put them on. In 1959, Ecuadors government declared 97.5 percent of the archipelago as a national park, aside from areas where people were already living. This meant no one would build houses on the penguins land. In 1986, 70,000 square kilometers of ocean surrounding the islands was made into a marine reserve, so the penguins food supply was safer. Land and sea are now protected
How Have People Interacted with the Galapagos Penguin and its Environment in a Negative Way? Most of the human impact on the penguins has been negative. They disturbed nesting habitats, so the penguins had to move. Humans also introduced cats, dogs, pigs and rats, which harmed the ecosystem and killed penguins and their offspring. Predators introduced by humans Humans also hurt penguins when illegal fishermen disrupt nests and penguins are caught in their nets. Some penguins die in nets each year.
The Biggest Negative Human Impact on Penguins is… …Global Warming! Penguins dont like it too hot. Galapagos penguins wont breed when its too hot and the Cromwell Current warms up, so as the earth gets warmer it hurts their populations.
International Efforts to Help the Penguins A group called the Galapagos Conservancy, based in Virginia, has been organized to help the penguins and other life on the Galapagos Islands. Their mission is to advance and support the conservation of the unique biodiversity and ecosystems of Galapagos through directed research, informed public policy, and building a sustainable society. The penguins are over there… (from )www.galapagos.org They've poured tens of million of dollars of private support into the Galapagos Islands and its wildlife, including the endangered penguins.
How do the Penguins Impact Humans? Most of the impact of penguins on humans is positive, because penguins bring in eco-tourism revenue, since they have a lot of charisma. Bird-watchers and wildlife enthusiasts come to the islands and spend money. Penguins are flightless birds, look down!!! The penguins can have a negative impact on commercial fishing, because they can eat up to 3000 tons of fish a year.
The Galapagos Penguin! I think youll agree, Galapagos penguins are pretty cool, as long as they can keep from getting too hot!
