Geolocators reveal that Plain Swifts winter in West Africa

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… Read More »

First record of Cinereous Vulture for Mauritania

Cinereous Vulture (Aegypius monachus) is considered an accidental visitor in Morocco. But based on recent observations, the species should be regarded as a migrant and wintering visitor in Morocco. For example, 4 birds were counted at Jbel Moussa in spring 2017 and 6 birds in spring 2016 (including 3 birds photographed together on 7 May).… Read More »

Important White-headed Duck wintering population in Morocco

Almost 1500 White-headed Ducks (Oxyura leucocephala) counted yesterday by Said Lahrouz and his team at Merja Fouwarate (Fouarat), a peri-urban wetland located at Kenitra (north-west Morocco). A more detailed census the next day, 1 January 2018, revealed a total of 1430 individuals, including 600 males (Lahrouz et al. 2018). This is probably the biggest wintering… Read More »

Spanish Imperial Eagle dispersion in North Africa in 2017

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).

4 Cinereous Vultures crossing the Strait of Gibraltar in one day

Yet another ‘big day’ for raptor migration (especially vultures) at the southern shore of the Strait of Gibraltar. Last Friday, Rachid El Khamlichi, Cécile Krystelle and Radu Adrian counted: 2700 Griffon Vultures (Gyps fulvus). We are now used to seeing such big numbers crossing the Strait in late autumn (October/November). 4 Cinereous Vultures (Aegypius monachus).… Read More »

Wing-tagging a Rüppell’s Vulture at Jbel Moussa, Morocco

Over five thousands Griffon Vultures (Gyps fulvus) migrate through northern Morocco twice a year, and an increasing number of Rüppell’s Vultures (Gyps rueppelli) are also migrating through the region (a paradox, since the latter species is declining in its West African breeding areas from where these vagrants are coming). Some of these vultures can end up… Read More »
