Annobon Scops-owl (Otus feae)

Scops feae


, 1903,



Hitherto considered conspecific with O. scops and/or O. senegalensis, but differs from former in its evidently distinct voice and several plumage characters (not enumerated here), and from latter in its possibly different voice (reportedly a “lightly trilled call” like high-pitched Tyto alba#R) (ns); much broader black streaking, streaks on crown fusing to form mainly blackish mid-crown (3); absence of pale grey areas throughout feathering (2); virtual absence of patterning on inner webs of flight-feathers, except for large whitish wedges (absent or much reduced in senegalensis) along edges of secondaries (2); slightly larger bill (on only specimen in NHMUK) (ns). However, these characters require confirmation from larger sample of (living) specimens (museum material very limited), while preliminary molecular evidence indicates close link with O. senegalensis#R. Monotypic.


Annobón I (Pagalu), in S Gulf of Guinea.
