Census of vultures and other raptors during the prenuptial migration 2016 on the southern shore of the Strait of Gibraltar, Jbel Moussa – Morocco

Between 22 February and 20 August 2016, the southern shore of the Strait of Gibraltar, in particular Jbel Moussa and its surroundings, experienced an important passage of soaring birds belonging to different species, of which several are rare in Morocco such as the Rüppell’s Vulture (Gyps rueppellii), the Cinereous Vulture (Aegypius monachus), the Spanish Imperial Eagle (Aquila adalberti) and the Lesser Spotted Eagle (Clanga pomarina). A Rüppell’s Vulture was recovered and then marked with wing-tags (white codes ‘M1’ on black background) and a radio transmitter.

During 68 days, depending to the prevailing weather conditions and in particular with moderate west winds, 2,658 Griffon Vultures were recorded (2.138 during the prenuptial campaign of 2015). A dozen ornithologists from several countries participated in these censuses. See the PDF below.
