Chinstrap Penguins, named for the thin black band beneath their heads, are among Antarctica’s most charismatic seabirds. Found on icy coasts and rocky islands, they form vast, noisy colonies that can number in the tens of thousands. Expert swimmers, chinstraps dive deep to catch krill and small fish, playing a vital role in the Southern Ocean food web. Their energetic behaviour — from porpoising through waves to carefully tending their nests — makes them a delight to observe. However, climate change and shifting sea-ice patterns threaten their food supply, highlighting the urgent need to protect these resilient and spirited birds
