A geolocator study revealed that Plain Swifts breeding in the Canary Islands winter in equatorial West Africa. Plain Swift (Apus unicolor) breeds in the Canary Islands and Madeira in the north-east Atlantic. The populations of these two archipelagos are believed to be partly migratory, with an unknown proportion of the breeding population departing the islands …

Dispersion and overwintering of Spanish Imperial Eagles (Aquila adalberti) in Morocco, and northern Africa in general, is becoming regular and in relatively good numbers (for an endangered ‘sedentary’ species). As in previous years, this autumn at least 4 eagles crossed the Strait of Gibraltar to North Africa. We say “at least” because not every bird …

The recent migration of two young Bonelli’s Eagles across the Strait of Gibraltar to Morocco shows an unknown dispersive movement in this species. This confirms once again the importance of North Africa to the Iberian raptors. The Bonelli’s Eagle (Aquila fasciata) is usually resident across its breeding range. However, some immature birds sometimes make large dispersive …

Tracking Spanish Imperial Eagles showed the scale of their movements in Morocco and Africa in general. In 2015, six young satellite-tracked Spanish Imperial Eagles (Aquila adalberti) visited North Africa from Andalusia, southern Spain. A recent article by researchers from the Doñana Biological Station (EBD-CSIC) and the Government of Andalusia explored the subject of these eagles’ …

After leaving their Sahelian wintering grounds, immature Spanish Short-toed Snake Eagles spend the summer in northern Africa instead of going back to their natal areas. The importance of the breeding and wintering areas of a bird population for understanding demography and for determining conservation strategies is well recognised. However, the other areas where birds spend …
