NO UK STATUS / IUCN Red List: Least Concern
A widely ranging species found from the Great Lakes to near the Southern edge of Brazil including across the Caribbean, although it mainly favours coastal sites particularly mudflats and mangroves. The subspecies aren't clearly understood how they intergrade and this bird falls within the border range of three and thus hasn't been identified. They are specialists in feeding on crustaceans and the bill sizes of the different populations correleate to the prey species within that range.
