Subspecies
No subspecies.
Exhibits a number of features (e.g. small size, short tail, grey plumage without prominent facial markings) that are not typical of present genus; although traditionally included here, may well merit separate generic status. Study of its breeding biology and social structure, virtually nothing of which is known, could shed light on its true taxonomic status.
