Emperor penguin colonies have been discovered and counted from space. For the last 15 years, British Antarctic Survey (BAS) scientists have been looking for new colonies by searching satellite imagery for their guano stains on the ice.
The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species and is endemic to Antarctica. The male and female are similar in plumage and size, reaching 100 cm (39 in) in length and weighing from 22 to 45 kg (49 to 99 lb).
Oct 26, 2024 · Emperor penguins, the largest of their kind, are remarkable for their migratory patterns across the harsh Antarctic environment. Their annual journey is a testament to their resilience and provides insights into ecological dynamics in polar regions.
Summer in the southern hemisphere is from January to March, and at this time when the ice is breaking up, the Emperor penguins head out to sea to binge on krill, squid and fish. As March brings with it the end of summer, they start to head inland towards their rookery at Snow Hill.

Emperor penguins live and breed on the frozen sea ice. At least three-quarters of their breeding colonies are vulnerable to the predicted future changes in sea ice. Warmer temperatures can affect emperor chick hatching times, and they may hatch at times when food is more scarce.
