Field notes

  • It possesses the largest wing-area-to-body-weight ratio of any bird, allowing it to soar for weeks on end using thermal updrafts.
  • Unlike most other seabirds, its feathers are not waterproof, meaning it can never land on the ocean surface without risk of drowning.
  • Males inflate a vibrant red gular sac for up to 20 minutes during courtship to attract females flying overhead.
  • It is a notorious kleptoparasite, frequently harassing boobies and terns in mid-air until they regurgitate their meals.
  • Its skeleton is incredibly lightweight, weighing less than the total weight of its feathers.
Habitat
Tropical and subtropical coastal waters, mangroves, and offshore islands.
Range
Tropical Atlantic and Pacific oceans, including the Caribbean, Gulf of Mexico, and the Galápagos Islands.
