In the Falkland Islands an unorthodox scenario protects many penguin colonies. The ears reside on either side of the head as holes covered by feathers. Penguin is one of those flightless birds that are endemic to Polar Regions such as Antarctica with perfect adaptability to sustain in extreme cooler days of the year. When the Cromwell Current fails to upwell and bring colder, nutrient rich water to the surface, penguins delay breeding presumably because of low food availability. The oil secreted through the uropygial gland also helps them to prevent dust and other sticky materials from getting on feathers.

Most penguin mates share egg incubations that can last between 33 and 56 days, depending on the species. Both eggs are incubated for 31 to 39 days. Warming in the polar regions has melted sea ice, which penguins depend on to find food and build nests. Experts warn at this rate the species could be headed for extinction. It is believed that the cold temperatures of Antarctica, where modern penguins evolved, contributed to the loss of these tastes as sweet, umami and bitter taste receptors function poorly in cold temperatures. 2023 SeaWorld Parks & Entertainment, Inc.
