| Bubo cinerascens Guérin-Méneville, 1843 |
The Greyish Eagle-owl or Vermiculated Eagle-owl, Bubo cinerascens, is a rather large owl of Africa.
It is closely related to the Spotted Eagle-owl, of which is it sometimes considered the northern subspecies, B. africanus cinerascens.[1][2]
It is found in the northern part of sub-Saharan Africa from Mauretania and Liberia east to Sudan and Somalia.[2] Its habitats include dry rocky deserts and open savannah, as well as lowland forests in Somalia.[3]
This species is about 43 cm (17 inches) long and weighs about 500 g (1.1 lb).[3] Like the Spotted Eagle-owl, the Greyish Eagle-owl has mottled dark brown, buff, and white upperparts and finely barred (vermiculated) underparts giving a greyish-brown appearance. It differs from the Spotted Eagle-owl in having dark brown (not yellow) eyes and a brownish facial disk marked with a heavy brown circle around each eye.[1] It also has morphological differences, such as being lighter though about the same length and having shorter tarsi. In the area of overlap, the Spotted Eagle-owl and the present species are not known to interbreed.[3]
