The lanner falcon (''Falco biarmicus'')〔Etymology: ''Falco'', Latin for a falcon. ''biarmicus'', Latin for "being twice armed", in reference to the additional sharp points behind the billtip. These are typical of falcons in general however, not just this species.〕 is a medium-sized bird of prey that breeds in Africa, southeast Europe and just into Asia.

European lanner falcons (''Falco biarmicus feldeggi'', also called Feldegg's falcon) have slate grey or brown-grey upperparts; most African subspecies are a paler blue grey above. The breast is streaked in northern birds, resembling greyish saker falcons, but the lanner has a reddish back to the head. Sexes are similar, but the browner young birds resemble saker falcons even more. However, sakers have a lighter top of the head and less clear head-side patterns. The lanner's call is a harsh "''wray-e''".
