Distribution and habitat
The sandy scops owl is found in equatorial west and central Africa and has a rather scattered distribution. It has been recorded from Guinea, Liberia, Ivory Coast, Ghana, Cameroon, Gabon, Congo, Democratic Republic of Congo and Central African Republic.
The sandy scops owl occurs in lowland evergreen forest, open canopy forest and scrub, or in open forest mosaic land.
The sandy scops owl is a very rare and liitle known bird, It is probably crepuscular and insectivorous feeding largely grasshoppers and crickets. The breeding is probably from in February–March.
Two subspecies are currently recognised.
- Otus icterorhynchus icterorhynchus: West Africa
- Otus icterorhynchus holerythrus: northern west central Africa.
The sandy scops owl is thought to be basal in the lineage of the genus Otus, along with the Sokoke scops owl Otus ireneae, but there has been no genetic material for testing from the sandy scops owl. In addition some authorities consider that the subspecies of sandy scops owl should be teated as two different species.
