AICays and seabird colonies
Birds of Culebra
The most sensitive richness occurs on cays that are refuges, not stages for close approach.
Reviewed:A distant view can be the best view.
The refuge includes dry forest, mangroves, lagoons, and 21 cays; it documents landbirds, waders, shorebirds, waterfowl, and seabirds.
Colonies and access change with breeding, management, seas, and safety. Check official notices and use operators that respect distances and closures.

01
From lagoon to cay
Lagoons concentrate herons, ducks, and shorebirds; forest and scrub hold Elaenia, Gray Kingbird, and hummingbirds; cays host terns and other seabirds.
Use a scope and scan from shore. Silhouette, flight pattern, and relative size can be documented without landing.
02
Colonies without disturbance
Do not land on closed cays, use drones, circle nests, or cause flights. Displaced adults expose eggs and chicks to heat and predation.
Ask an operator about permits and practices before departure. If birds change behavior because of the boat, increase distance.

01
May I visit nesting cays?
Do not assume so. Many have restrictions; confirm with the refuge and respect closures and distance.
02
Do I need binoculars or a scope?
Binoculars are enough to begin; a scope lets you study cays and lagoons without approaching.
03
How do I verify an identification or claim?
Compare more than one mark, check date and place, open the linked profile, and consult the sources published at the end of the guide.
