Distribution and population

Nyctanassa carcinocatactes is known from subfossil remains from Bermuda (Olson and Wingate 2006). Reports from 1610 refer to numerous herons fitting the likely description of this species (Hume and Walters 2012), but it probably became extinct during the early 17th century shortly after colonisation by humans.


May have fed on large land crabs (Olson and Wingate 2006).


It was probably driven to extinction by invasive predators such as feral cats, hunting, and perhaps a shortage of prey (Hume and Walters 2012).
