Open this record in the interactive AtlasAbout Gull-billed Tern
Gull-billed Tern (Gelochelidon nilotica) appears in the wider Hawaiian bird catalog, but the Bishop Museum's 2017 island checklist has no Kauaʻi occurrence code for it. An island-specific record is needed before claiming local presence.
Kauaʻi evidence
A Hawaiʻi-level record is available, but the species needs a documented Kauaʻi observation before local ecological conclusions are drawn.

Habitat and ecology
- Habitats
- Cliffs
- Food and resource needs
- For Kauaʻi, Gull-billed Tern has no standing local food dependency until an occurrence is validated. If recorded, attach the observation to transient access to marine prey such as fish, squid, crustaceans, areas schooling prey, carrion, or kleptoparasitic food pathways depending on the seabird role.
- Reproduction
- Breeding on Kauaʻi is not established; seasonal resting and foraging habitat may be relevant.
- Shelter
- Shelter and structure within cliffs.
Threats and conservation
- Threats
- Predation at colonies, light fallout, powerline/collision mortality, fishery interaction, coastal disturbance, marine food-web change, and climate/ocean condition shifts
- Conservation actions
- Predator control, colony fencing where applicable, light reduction, fallout response, burrow/colony monitoring, fishery-risk mitigation, and protected nesting habitat
- Monitoring
- Document date, place, observer, habitat, behavior, and supporting media for any Kauaʻi observation.
- Data gaps
- A documented Kauaʻi observation with date, place, observer, and supporting media is needed
