Fewer than 50 adult Spotless Crakes (Porzana tabuensis) plus 24 chicks and four juveniles were found on Aorangi in February and March 1980. They were confined to the valley and preferred a low mixed forest which is being replaced by a less favoured habitat. Habitat preference is discussed and related to changes in numbers in the past. Clutch size is lower than on the mainland and chick production probably lower. The breeding cycle is long. Some observations on the adult-chick relationship are presented.
