Greyish eagle-owl

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 centimetres (17 in) long and weighs about 500 grams (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]
