Lanner Falcon
Falco biarmicus
It is a large falcon, at 43–50 cm (17–20 in) length with a wingspan of 95–105 cm (37–41 in). Eurasian 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".

Red-footed Falcon
Falco vespertinus
It is a medium-small, long-winged species. The adult male is all blue-grey, except for his red undertail and legs; its underwings are uniformly grey.

Young birds are brown above and buff below with dark streaks, and a face pattern like the female. Red-footed falcons are 28–34 cm (11–13 in) in length with a wingspan of 65–75 cm (26–30 in). The average mass is 155 g (5.5 oz).
