Short note on penguin bird
Penguins are a group of flightless birds that are native to the Southern Hemisphere, particularly Antarctica. There are over 17 different species of penguins, ranging in size from the tiny fairy penguin, which is only about 16 inches tall, to the emperor penguin, which can stand up to almost 4 feet tall.
One of the most notable features of penguins is their tuxedo-like appearance, with a black back and white front. This coloring serves as camouflage in the water, as the black back blends in with the deep sea, while the white front blends in with the sun reflecting off the surface of the water. This helps penguins to avoid predators and hunt for food.
Penguins are excellent swimmers and can dive to great depths in search of fish, squid, and other marine life to eat. They use their wings, which have evolved into flippers, to propel themselves through the water at speeds of up to 15 miles per hour. On land, penguins are awkward and waddle rather than walk, but in the water they are graceful and agile.
Penguins are social animals and often live in large colonies, known as rookeries. During the breeding season, male penguins will build nests out of rocks or other materials and try to attract a mate with displays of courtship. Once a female has laid her eggs, the male will incubate them while the female goes out to sea to hunt for food. After the eggs hatch, both parents take turns caring for the chicks and bringing them food until they are old enough to fend for themselves.
Penguins are an important part of the marine ecosystem and serve as indicators of the health of the oceans. Many species of penguins are facing threats from habitat loss, overfishing, and climate change, and are classified as endangered or vulnerable by the International Union for Conservation of Nature.
Overall, penguins are fascinating and unique birds that have adapted to living in the cold, harsh environment of the Southern Hemisphere. They are known for their distinctive appearance, impressive swimming abilities, and social behavior, and play an important role in the marine ecosystem.

Penguins also come in shades of blue, grey, orange and yellow, along with certain species having brightly colored feathers. Proceedings of the Royal Society of London B. This forms a tapered, flat flipper for swimming. Another assumption that goes around them is that they are mammals because of their large size and great parenting. The display of ultraviolet could contribute to mate selection with both females and males preferring mates with stronger displays of ultraviolet reflectance. Senses Many aspects of the senses of penguins also reflect their sea-going habits. A Paleocene penguin from New Zealand substantiates multiple origins of gigantism in fossil Sphenisciformes".

The discovery of these ancient penguins was based on an analysis of four separate specimens from North Canterbury, New Zealand that are some of the best-preserved avian fossils from that era.

Retrieved June 2, 2020. Once a pair decides to mate, a series of courting behaviors follow, cementing the bond that will carry them through the trying months of parenthood. The two species of Waimanu penguins are currently considered the basal ancestors, meaning they are considered the earliest common ancestor of all penguins. They eat mostly small fish, but occasionally will consume krill and small squid. As any SCUBA diver knows, pressure changes from diving can damage the fragile structures within the ear. The individual function of each feather type is still unclear, but plumules are nearly four times more numerous than contour feathers, leading scientists to believe they serve an important purpose. The crested penguins will eventually only raise one chick; the second egg may not even hatch or in some cases the smaller chick will be ignored by the parents and eventually die which is often the case for Macaroni penguins.
