The chinstrap penguin (Pygoscelis antarcticus) is a species of penguin that inhabits a variety of islands and shores in the Southern Pacific and the Antarctic Oceans. Its name stems from the narrow black band under its head, which makes it appear as if it were wearing a black helmet, making it easy to identify. [ 2 ]
Support for this etymology can be found in the alternative Germanic word for penguin, fettgans or 'fat-goose', and the related Dutch word vetgans. Adult male penguins are sometimes called cocks, females sometimes called hens; a group of penguins on land is a waddle, and a group of penguins in the water is a raft.
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.
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.
As an example, the great tit, a European songbird, uses such a signal to call on nearby birds to harass a perched bird of prey, such as an owl. This call occurs in the 4.5kHz range, [66] and carries over long distances. However, when such prey species are in flight, they employ an alarm signal in the 7–8 kHz range.
Sphenisciformes (from the Latin for "wedge-shaped") is the taxonomic order to which the penguins belong. BirdLife International has assessed 18 species. 16 (89% of total species) have had their population estimated: those missing are the king and little penguins , both of which have been assessed as being of least concern .
A study has estimated that there are about 3.79 million pairs of Adélie, 387,000 pairs of gentoo, and 8 million pairs of chinstrap penguins in their particular areas, [7] making up 90% of Antarctic avian biomass.
Millions of chinstrap penguins settle on the isolated volcanic Zavodovski Island in the South Atlantic Ocean, enduring hostile environments such as extreme mass waves, violent storms, ravaging skuas, and noxious volcanic gases. The mother penguin guards her chicks against the skuas while her partner returns to their nesting place with food ...
