This last confirmed breeding record of this species was in 1937, and it has not been reported since 1988. It may have gone extinct as a result of habitat destruction both on the breeding and wintering grounds. However, it cannot yet be presumed to be Extinct until all remnant patches of possible breeding habitat (e.g. Congaree swamp in South Carolina) have been searched, and recent unconfirmed reports have been followed up. Any remaining population is likely to be tiny, and for these reasons it is treated as Critically Endangered (Possibly Extinct).
