Artamia comorensis

Grand Comoro Island; error = Mohéli


Until recently considered conspecific with C. madagascarinus, but differs (in female) in its all violet-blue crown to basal tail vs more turquoise-blue crown shading to strong turquoise-green mantle to basal tail (3); pale blue, white-streaked head sides with no (or vestigial) black vs rich turquoise-blue head sides with black lores, ocular area and chin (3); pure pinkish-buff vs duller, usually grey-tinged buff underparts (1); (in male) in greatly reduced black around eye and on chin (ns) and richer blue upperparts (ns[1]); and (in both sexes) slightly larger size indicated by rather longer bill (at least 1); voices similar, but that of present species seems to be somewhat more varied, with some notes which are less grating (at least 1). Two subspecies currently recognized.
