The Galápagos penguin (Spheniscus mendiculus) is a penguin endemic to the Galápagos Islands of Ecuador. It is the only penguin found north of the equator. [4] Most inhabit Fernandina Island and the west coast of Isabela Island. [5] The cool waters of the Humboldt and Cromwell Currents allow it to survive
The life-cycle of the emperor penguin. The penguins start courtship in March or April, when the temperature can be as low as −40 °C (−40 °F). A lone male gives an ecstatic display, where it stands still and places its head on its chest before inhaling and giving a courtship call for 1–2 seconds; it then moves around the colony and ...
The small penguins do not usually dive deep; they catch their prey near the surface in dives that normally last only one or two minutes. Larger penguins can dive deep in case of need. Emperor penguins are the world's deepest-diving birds. They can dive to depths of approximately 550 meters (1,800 feet) while searching for food. [47]
Magellanic penguin on Argentina's coast Skeleton of a Magellanic penguin. Magellanic penguins are medium-sized penguins which grow to be 61–76 cm (24–30 in) tall and weigh between 2.7 and 6.5 kg (6.0 and 14.3 lb). [3] The males are larger than the females, and the weight of both drops while the parents raise their young.
The African penguin (Spheniscus demersus), also known as Cape penguin or South African penguin, is a species of penguin confined to southern African waters. It is the only penguin found in the Old World. Like all penguins, it is flightless, with a streamlined body and wings stiffened and flattened into flippers for a marine habitat. Adults ...
The current maximum dive recorded is 343 metres in the Falkland Islands region, [21] and a maximum time submerged of 552 seconds was recorded at the Crozet Islands. [22] The king penguin dives during daylight hours to depths of 100–300 meters (350–1000 feet), spending around five minutes submerged, and to less than 30 metres (98 ft) at night.
The art of nodding off appears to have been mastered by breeding chinstrap penguins, who take more than 10,000 naps a day, with each nap lasting an average of four seconds, according to a new study.
Humboldt penguins need up to half an hour to recover to normal heart rates after human approach, however, this time decreases with repeated visitation. [9] Cumulative stress by frequent visits and delayed return of foraging partners leads to nest desertion, consequently causing decreased breeding success at frequently visited sites.
