Vultures

An African White-backed Vulture (Gyps africanus) seen at the Estação Biológica do Garducho, near Mourão on 24th August is just the second record of this species for Portugal and only the fifth for Europe.

African White-backed Vulture (Tanzania)

It was seen at one of the vulture feeding stations set up in that part of Eastern Alentejo by the LIFE Lince Abutre project, which aims to contribute to the improvement of the survival, feeding and breeding conditions of the Iberian lynx (Lynx pardinus) and the Cinereous or European Black Vulture (Aegypius monachus) in southeast Portugal but also benefits several other threatened species.

European Black Vulture (Portugal)

Only three weeks earlier, there was a remarkable report of five Rüppell’s Griffon Vultures (Gyps rueppelli), another African species, also in the Eastern Alentejo.  Sightings of Rüppell’s Griffons in ones and twos have become regular in Portugal and Spain in recent years, most of them at Tarifa and Sagres, with some speculation about how many different individuals might be involved, so the occurrence of five together was very interesting.

Rüppell’s Griffon (Ethiopia)

It is assumed that Rüppell’s Griffons and now White-backed Vultures mix with wintering Eurasian Griffons (Gyps fulvus) in West Africa, and then come to Europe with them.  Rüppell’s has also tried to breed in Iberia, in hybrid pairings with Eurasian Griffons, but to date there has not been any evidence of success.

Eurasian Griffon (Portugal)

Last year a Rüppell’s Griffon was wing-tagged in Portugal, and was subsequently seen in France and Spain, confirming that these birds range widely across the continent.

So now we have six species of vultures to look out for: European Black, Eurasian Griffon, Rüppell’s Griffon, Egyptian (Neophron percnopterus), African White-backed and Lammergeier (Gypaetus barbatus).  Lammergeiers haven’t been seen here for a very long time but they have been re-introduced in Spain and individuals are known from satellite-tracking to have occasionally crossed the border to fly unseen over Portugal.

Egyptian Vultures (Ethiopia)

It is timely that we are writing about vultures as the first Saturday in September each year is International Vulture Awareness Day.  It also gives us an opportunity to draw attention once again to the on-line petition to ban the use in Europe of diclofenac, the drug that has been responsible for wiping out huge numbers of vultures in India, Pakistan and Nepal.  You can read more about that here and here you can donate towards efforts being made by Birdlife International to save vultures in Europe and Africa from the fate that has befallen so many in Asia.

Vultures need our help!
