The Brown Noddy is a sleek, chocolate-colored seabird with a snowy white cap that makes it look like it’s always wearing a classy little helmet. It’s known for its friendly head-nodding gestures—yep, it actually nods—especially during courtship or when greeting its mate. Gliding effortlessly over tropical waves, this chilled-out bird nests in noisy colonies on remote islands, bringing serious cool vibes to the high seas.
