A new race of Accipiter virgatus and validity of the race pullus of the Common Noddy for Riu Kiu Is

Abstract

A new subspecies, Accipiter virgatus iwasakii, subsp. nov., was described as a smaller resident Riu Kiu race with more rounded wing-formular compared with the northern(Korean)form. Its known range is Ishigaki and Iromote islands of the South Riu Kius.
The Riu Kiu population of Anous stolidus is smaller and paler than that of Micronesia, A. s. pileatus (Scopoli). Therefore the name, A. s. pullus Bangs, is to be recognized for the birds of Ishigaki and Iriomote islands, S. Riu Kius.
