Open this record in the interactive AtlasAbout American Avocet
The American Avocet is a tall, elegant shorebird with very long blue-gray legs, bold black-and-white wings, and a slender bill that curves distinctly upward. During the breeding season the head and neck become warm cinnamon; outside that season they are pale gray to white. Females often have a more strongly curved bill than males. In flight, the broad white wing patches and long legs extending behind the body make the species conspicuous even at a distance.
American Avocets feed in shallow fresh, brackish, and saline wetlands, including marshes, salt ponds, mudflats, lagoons, impoundments, and flooded fields. Their signature technique is scything: the slightly open bill sweeps from side to side through the water to capture brine flies, midges, beetles, small crustaceans, and other aquatic invertebrates. They also peck or plunge for prey and occasionally take small fish and aquatic seeds. Outside the breeding season they often feed and rest in flocks with other shorebirds.
Pairs select open nest sites together, usually on a bare island, dike, or shoreline with little vegetation. The nest is a shallow ground scrape lined to varying degrees with grass, feathers, pebbles, or other nearby material. A typical clutch contains three or four eggs, incubation lasts about eighteen to thirty days, and both adults defend the nest. The downy chicks can walk soon after hatching and leave the nest with their parents; most pairs raise a single brood in a season.
Across its normal North American range the American Avocet is considered a species of relatively low conservation concern, although wetland loss, disturbance, and contamination by selenium, mercury, and other pollutants can reduce breeding success. In Hawaiʻi it is a vagrant rather than a resident bird. The current Atlas record does not confirm an occurrence on Kauaʻi, so any island sighting should be supported by photographs, dates, location details, and expert review; breeding on Kauaʻi is not established.
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
- Wetlands · Ponds · Mudflats
- Food and resource needs
- For Kauaʻi, American Avocet has no standing local food dependency until an occurrence is validated. If recorded, attach the observation to transient access to intertidal, mudflat, wetland, turf, or freshwater invertebrates, with seeds or plant matter included for rail/coot-type records.
- Reproduction
- Breeding on Kauaʻi is not established; seasonal resting and foraging habitat may be relevant.
- Shelter
- Shelter and structure within wetlands, ponds, mudflats.
Threats and conservation
- Threats
- Wetland/coastal habitat state, survey detectability, disturbance, avian disease, and rare-record review are the open questions
- Conservation actions
- Document date, place, observer, habitat, and supporting media · Confirm identification and Kauaʻi occurrence before local conservation use
- 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
Process and seasonal context
- Seasonal timing
- Rare Or Unresolved Hawaiian Shorebird Record Needs Kauai Review
- Seasonal description
- American Avocet (Recurvirostra americana) 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.
