Meet the red-footed booby
This social seabird is found in colonies near warm coastal waters around the world. Petite (for a booby), the red-footed booby is uniquely polymorphic—having different physical variations within the species. The usually brown chick will develop its red feet plus one of several possible plumage palettes by the time it becomes an adult at around 2 to 3 years old.

From the trees to the seas
Unlike its blue-footed cousins, the red-footed booby nests in trees. If you find yourself walking around the Galapagos, you may see the two booby cousins within feet of each other—the red in the trees and the blue on the ground nearby!
The red-footed booby's red feet are as functional as they are bright, with articulated joints for gripping tree branches plus webbing for smooth swimming at sea.
Built-in hunting gear
From feathers to feet, this booby's body helps it hunt. A long, serrated beak facilitates a dive-and-snatch strategy for finding dinner. When heading off to hunt, it will cruise 30–40 feet in the air, then dive into the ocean to snatch fish. Usually, these dives are shallow, only about 8 feet or less, but scientists are finding that different colonies have different strategies for finding food, so there could be red-footed boobies diving much deeper!
Nobody wants to get water in their nostrils, red-footed boobies included. Another of its adaptations for diving is a set of secondary nostrils that can close up to keep water out during a high-speed dive (to complement its always-closed primary nostrils). Its eyes stay dry while diving, too! A nictitating membrane over its eyes, sort of like a clear third eyelid, acts as a kind of goggle.
How fast does the booby dive? It's safe to say "pretty fast" but hard to say exactly—each species of booby has unique hunting patterns.
Conservation
Red-footed boobies are plentiful in the wild. However, they can end up as bycatch as a result of some fishing methods.
Cool facts
- As curious animals that live on islands far away from humans, the booby family of birds doesn't have a natural fear of humans. That's why Spanish sailors used to call these birds "bobo" when they would fly straight onto fishing boats—the hungry sailors frequently feasted on a fearless "bobo" dinner. Eventually, the word "bobo" became "booby," the current name for the genus.
