The Lanner Falcon (Falco biarmicus) is a medium-sized bird of prey that breeds in Africa, southeast Europe and just into Asia.
It is a large falcon, at 43–50 cm length with a wingspan of 95–105 cm. 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. Sexes are similar.
The lanner falcon is a bird of open country and savanna. It usually hunts by horizontal pursuit, rather than the peregrine falcon's stoop from a height, and takes mainly bird prey in flight.
They are bred in captivity for falconry; hybrids with the peregrine ("perilanners") are also often seen. Merret (1666) claimed that the "lanar" lived in Sherwood Forest and the Forest of Dean in England; such populations would seem to derive from escaped hunting birds of the nobility.
