Taxonomic note
Nesoenas duboisi (del Hoyo and Collar 2014) was previously placed in the genus Columba.

There were probably two other native pigeons on the island-a slaty, blue-winged Alectroenas, and unidentified ramiers. All three apparently became extinct in the early 1700s (Cheke 1987). Adler (1994) confused the situation by applying the name duboisi to the (undescribed) Alectroenas. Archeological work is needed to clarify the situation.
