Ogilvie-Grant and H. O. Forbes, 1899,
Until recently treated as conspecific with O. senegalensis (including O. pamelae), but differs in its song, a repeated low-pitched “woop woop da-pwoorp” vs a soft purring “kjurrrr” in both senegalensis and pamelae (although latter two differ from each other) (score 4); very short, blunt ear-tufts (no measurements available, but allow 1); greatly reduced dark streaking on upperparts (2); whiter, less marked belly (2); pale buffy-grey upper breast encircling lower line of facial disc (1); distinctly if subtly rustier primary coverts (ns). Call resembles but is not identical to that of O. sunia, and molecular evidence also points to relationship with this species and O. insularis#R, but morphological differences considerable (not enumerated here). Monotypic.
