Thryothorus luscinius

Sometimes treated as conspecific with A. syrinx, and sometimes also with A. rehsei, but differs from both in distinctly larger size, much longer bill, and song. Dark race yamashinae, from Pagan I (NC Northern Marianas), extinct; described race astrolabii, of uncertain origin but possibly from Yap (in W Caroline Is), also extinct. Two extant subspecies recognized.
