Penguins are a group of aquatic flightless birds. They live almost exclusively in the Southern Hemisphere, with only one species, the Galapagos penguin, found north of the equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage, and their wings have evolved into flippers. Most penguins feed on krill, fish, squid and other forms of sea life which they catch while swimming underwater. They spend roughly half of their lives on land and the other half in the sea.

Although almost all penguin species are native to the Southern Hemisphere, they are not found only in cold climates, such as Antarctica. In fact, only a few species of penguin live so far south. Several species are found in the temperate zone, and one species, the Galápagos penguin, lives near the equator. — Wikipedia

    Seabird species such as gulls and pelicans are often overlooked when it comes to conservation and can struggle to capture the public eye. To raise awareness of their importance to people and the ecosystems we depend on, a Science & Society article appearing August 6 in the journal Trends in Ecology & Evolution looks at something that most of us find off-putting: their poop. The researchers say that the poop, which is also known as guano and serves as a source of fertilizer and a key […]

    A pair of researchers, one with Kochi University, the other Katsurahama Aquarium, both in Japan, has refined the estimate of the amount of pressure required by an Adélie penguin to shoot its feces a necessary distance. Hiroyuki Tajima and Fumiya Fujisawa have written a paper describing their new calculations and what it could mean for zookeepers.
