Barbary falcon (Falco pelegrinoides)
Like the peregrine falcon, with which it often considered conspecific, the Barbary falcon exhibits dazzling aerial mastery and speed. Although this medium to largish falcon is similar in appearance to the peregrine, it is a notably slimmer bird with a less broad head and a shallower chest. The upperparts to its plumage are generally blue-grey while the head has a distinctive pattern comprising a brown cap, rufous forehead, nape and sides of the crown, and dusky patches around the eyes. These patches extend down into a thin dusky moustache and back into an eye-stripe that together outline a creamy cheek patch. The throat is whitish, but otherwise the underparts are cream to cinnamon with light black spots or streaks on the belly. The primary feathers are dark while the undersides of the long wings are thinly barred, and the short, square tail is broadly barred black. Although the sexes are similar in appearance, the female Barbary falcon is substantially larger in size. Two subspecies of the Barbary falcon are recognized: Falco pelegrinoides pelegrinoides and the slightly larger and paler Falco pelegrinoides babylonicus.
