Taxonomy
editIt is sometimes assigned to the genus Nycticorax. It was first described by Storrs L. Olson & David B. Wingate (2006)[2] from subfossil material found in the Pleistocene and Holocene deposits in caves and ponds of Bermuda.
Description
editIts anatomy was rather similar to its living relative, the yellow-crowned night heron (Nyctanassa violacea), but it had a heavier bill, a more massive skull and more robust hind limbs. The specialization of the bill and the hind limbs showed that it was apparently adapted to the feeding on land crabs.[2]
Extinction
editThere are also early historian reports referring to the species. It possibly became extinct due to the settlement of the Bermuda islands in the 17th century. On Bermuda, the aforementioned yellow-crowned night heron was introduced in the 1970s to act as its proxy in the ecosystem, mostly to act as biological control for land crabs, which have dug holes that interfere with the island's golf courses. Due to being generalist feeders instead of specialised feeders like N. carcinocatactes, N. violacea has been recorded to have caused record declines in land crab populations, as well as feeding on the critically endangered Bermuda rock lizard.[2]
