Galápagos penguins protect their eggs and chicks from the hot sun by keeping them in deep crevices in the rocks. Galápagos penguin swimming in water. The Galápagos penguins' flipper-like wings and streamlined bodies enhance their easy movements in water. [14] Their white and black colors also aid in thermal regulation and camouflaging. [14]
Emperor penguins are also known to dive to depths of more than 1,640 feet (500 meters) making them the deepest diving birds in the world, where they are able to hold their breath for up to 20 ...
The weight also varies by season, as both male and female penguins lose substantial mass while raising hatchlings and incubating their egg. Male emperor penguins must withstand the extreme Antarctic winter cold for more than two months while protecting their eggs; eating nothing during this time, male emperors will lose around 12 kg (26 lb ...
Penguin eggs are smaller than any other bird species when compared proportionally to the weight of the parent birds; at 52 g (2 oz), the little penguin egg is 4.7% of its mothers' weight, and the 450 g (1 lb) emperor penguin egg is 2.3%. [62]
This behaviour will occur when multiple adult penguins rear their chicks together in a group formation. [3] In the majority of penguin crèches there will be more chicks than adults. [9] The main advantage of the crèche formation in penguins is to aid in thermoregulation [9] [10] but the formation also helps prevent predation and aggression. [3]
The whalers also used penguin oil for lamps, heating and cooking, in addition to eating the birds and their eggs. Macquarie Island currently has around 70,000 pairs. The non-breeding range is unknown; many vagrant birds have been seen on the Antarctic peninsula as well as in South Africa, Australia, and New Zealand.
The members of this genus are often called "brush-tailed penguins", a reference to their long, stiff tail feathers. [11] The birds regularly use their tails for support, and the stiff feathers sweep the ground as the penguins walk. [12] The specific name adeliae indicates the location from which the type specimen was collected. [5]
Chinstrap penguin. Penguins are birds in the family Spheniscidae in the monotypic order Sphenisciformes. [1] They inhabit high-productivity marine habitats, almost exclusively in the Southern Hemisphere; the only species to occur north of the Equator is the Galapagos penguin.
