Palau Islands


Until recently considered conspecific with E. tenuirostre, but differs from all taxa in that complex (here split from HBW arrangement into nine species) in its very small size (allow 4); scalier rump in female (2) except against E. nesiotis and E. remotum heinrothi (discounting variable vague grey scaling in E. t. tenuirostre); and fairly distinctive call, a mellow upslurred whistle (2)#R. This last is shared with E. nesiotis, from which it differs in its smaller size (4); blacker plumage in male (1); much less rusty ground colour in female (2); barring all across underparts in female (2); and less extensive vocabulary (1). Differs from E. r. heinrothi in its small size (4); much more spaced barring on female below, with chin plain (2); and voice (2). Name monacha is a noun, and thus invariable#R. Monotypic.

Virtually nothing known, although family groups have been reported in Nov.



Status and conservation

Not globally threatened (Least Concern). Restricted-range species: confined to Palau EBA. Was considered uncommon on all islands within species’ range in the 1940s and 1970s... read more
