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
Biology is the scientific study of life. Biologists study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations. Biologists also study and classify the various forms of life, from prokaryotic organisms such as archaea and bacteria to eukaryotic organisms such as protists, fungi, plants, and animals. — Wikipedia

- Ardern in a flap as wren rocks N. Zealand's bird...on October 31, 2022 at 8:36 am
A tiny mountain-dwelling wren was the surprise winner Monday of New Zealand's controversial bird of the year competition, which even had Prime Minister Jacinda Ardern in a flap.
- Emperor penguins granted protections under...on October 25, 2022 at 9:23 pm
Today, the U.S. Fish and Wildlife Service (USFWS) announced that emperor penguins have been listed as a threatened species under the Endangered Species Act (ESA) based on evidence that the animal's sea ice habitat is shrinking and is likely to continue to do so over the next several decades. This listing comes more than one year after a USFWS proposal to list the species, and confirms that the animal is at risk of becoming an endangered species—in danger of extinction—in the foreseeable […]

Ice buildup on powerlines and electric towers brought the northern US and southern Canada to a standstill during the Great Ice Storm of 1998, leaving many in the cold and dark for days and even weeks.

While most of the world's oceans are warming due to climate change, a new CU Boulder study explains how the waters around the Galápagos Islands are staying cool and getting colder.
- Why erect-crested penguins reject their first egg...on October 12, 2022 at 7:00 pm
A new analysis of old data suggests that the endangered erect-crested penguin's bizarre nesting habits—rejecting the first egg they lay—is because they can't feed two chicks, and the second, larger egg has a better chance of success. Lloyd Davis of the University of Otago in New Zealand and colleagues describe these findings and their implications for penguin conservation in the open-access journal PLOS ONE on October 12, 2022.
