St. Helena Cuckoo

Nannococcyx psix Olson, SL 1975

The Saint Helena cuckoo is an extinct bird. It was confirmed to have previously existed by a single humerus. Compared to other cuckoos, it was relatively small, and it probably lived in forests on the island of Saint Helena. Its extinction was a result of deforestation on the island in the 18th century.
