![]() ![]() The idea of this historical route was supported by two observations made in Tanzania and Somalia ( Stresemann 1954 Turner 1978), where flocks of several hundred individuals were observed. Since the 1950s, Eleonora's falcons have been thought to follow a species-specific migration route, taking them down the entire Mediterranean towards Suez ( Stresemann 1954), down the Red Sea coast, around the Horn of Africa and along the East African coast, before arriving in Madagascar ( figure 1, dotted line). The nestlings fledge within 35–37 days after hatching ( Vaughan 1961 Walter 1979 b) and at the age of only 10 weeks they start their enormous journey of several thousand kilometres to their wintering grounds in Madagascar, where 70 per cent of the world population is estimated to overwinter ( Walter 1979 b). Together with the smaller sooty falcon ( Falco concolor), it is the only raptor species that delays its breeding period until late summer and feeds its young with migrating passerines during the peak of autumn migration ( Walter 1979 b). It mainly breeds on the cliffs of small islands in the Mediterranean and Macronesia in large colonies of up to 630 breeding pairs (Morocco). We propose the idea of an orientation mechanism that naive falcons could apply during their long-distance migration towards their faraway wintering area located in the open ocean.Įleonora's falcon ( Falco eleonorae) is a highly specialized bird of prey with a peculiar breeding biology. As juveniles migrated independently of adults, we discuss inherited navigation strategies forming part of a complex navigation system. Furthermore, juvenile falcons migrated via West Africa to Madagascar and two juveniles could be tracked during spring migration and to their summering areas in East and West Africa. In our study, we used satellite telemetry to investigate the real migration route of Eleonora's falcons and found that the species displayed a highly individual migration pattern. Since the 1950s, this slender winged falcon has been believed to migrate along a historical route via the Red Sea to its main wintering area in Madagascar. ![]() Laafi (FR) 28-1 (9-6) Midfield, pushed along over 3f out, made no impression from 2f, 13th of 15, 36 3/4l behind Burdett Road (8-13) at Ascot 1m 2f hcp stks (2) gf in Jun.Eleonora's falcon ( Falco eleonorae) is a rare raptor species that delays its breeding period until late summer to feed its young with passerines at the peak of autumn migration.
