Greyish eagle-owl

The greyish eagle-owl or vermiculated eagle-owl (Bubo cinerascens) is a rather large owl of the northern part of sub-Saharan Africa. It was previously regarded as the northern subspecies of the spotted eagle-owl (Bubo africanus).

This species is about 43 cm (17 in) long and weighs about 500 g (18 oz). 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. It also has morphological differences, such as being lighter though about the same length and having shorter tarsi.
