Population 2.6M – 4.5M

During the breeding season, this bird is absolutely stunning and impossible to mistake for any of its relatives. While other terns usually have white bodies and black caps, the white-winged tern does the exact opposite: it sports a deep, velvety jet-black body that contrasts sharply with its namesake “white wings.” To finish off this high-fashion look, it has a bright red beak and matching red legs that look like tiny, stylish boots.

While many of its cousins are battling ocean waves, this bird is a specialist of freshwater marshes, lakes, and even flooded rice paddies. Because of this, it has developed a very specific and elegant way of eating. You won’t see this bird “crash-diving” into deep water like a clumsy stone. Instead, it is an elite aerial acrobat. It “hawks” for food, meaning it snatches dragonflies and other insects right out of the air with incredible precision. If it does feed from the water, it gently dips its beak to pluck a snack off the surface while staying perfectly dry.

One of the most fascinating things about this bird is its incredible “seasonal wardrobe.” While its black-and-white breeding outfit is iconic, the white-winged tern is a master of disguise. Once the summer ends, it undergoes a total transformation, shedding its dark feathers for a more conservative grey-and-white look to blend in during its long travels. And those travels are nothing short of heroic. Despite being a relatively small and delicate-looking bird, it is a world-class traveler. These birds are known to fly staggering distances, migrating from the quiet marshes of Europe and Asia to the tropical wetlands of Africa, Australia, and even the Philippines.
