White Tern

Gygis alba

Also known as Common White Tern, Fairy Tern, Angel Tern, White Noddy

White Terns are famous for laying a single egg directly onto bare tree branches or coral ledges without building a nest. Adults hunt small pelagic fish and squid near the water surface, often carrying several fish crosswise in their sharp black bills back to their young. Their stark white plumage, large dark eyes, and delicate fluttering flight make them an unmistakable sight across tropical oceans.

Support conservation
Keep distance from nesting trees and never touch or shake branches where birds are perching.
Responsible observation
  • Nesting Caution: Avoid shaking branches on island trees where eggs sit precariously balanced.
  • Observer Distance: Watch from a respectful distance to prevent brooding parents from flushing.
  • Identification: Look for their distinctive fluttering, butterfly-like flight over coastal foliage.
