Peregrine falcon
Barbary falcon

The Barbary falcon is a subspecies of the peregrine falcon that inhabits parts of North Africa; namely, from the Canary Islands to the Arabian Peninsula. There is discussion concerning the taxonomic status of the bird, with some considering it a subspecies of the peregrine falcon and others considering it a full species with two subspecies (White et al. 2013). Compared to the other peregrine falcon subspecies, Barbary falcons sport a slimmer body and a distinct plumage color pattern. Despite numbers and range of these birds throughout the Canary Islands generally increasing, they are considered endangered, with human interference through falconry and shooting threatening their well-being. Falconry can further complicate the speciation and genetics of these Canary Islands falcons, as the practice promotes genetic mixing between individuals from outside the islands with those originating from the islands. Population density of the Barbary falcons on Tenerife, the biggest of the seven major Canary Islands, was found to be 1.27 pairs/100 km, with the mean distance between pairs being 5869 ± 3338 m. The falcons were only observed near large and natural cliffs with a mean altitude of 697.6 m. Falcons show an affinity for tall cliffs away from human-mediated establishments and presence.

Barbary falcons have a red neck patch, but otherwise differ in appearance from the peregrine falcon proper merely according to Gloger's rule, relating pigmentation to environmental humidity. The Barbary falcon has a peculiar way of flying, beating only the outer part of its wings as fulmars sometimes do; this also occurs in the peregrine falcon, but less often and far less pronounced. The Barbary falcon's shoulder and pelvis bones are stout by comparison with the peregrine falcon and its feet are smaller. Barbary falcons breed at different times of year than neighboring peregrine falcon subspecies, but they are capable of interbreeding. There is a 0.6–0.7% genetic distance in the peregrine falcon-Barbary falcon ("peregrinoid") complex.
