Two juvenile griffon vultures from the Japanese Rhodopes had been geared up with GPS transmitters lately by the native rewilding staff. This expertise will present important knowledge on the distribution, migration and potential threats to the birds, enhancing conservation of this magnificent but domestically endangered species.
The top of June noticed two extra griffon vultures tagged with GPS transmitters within the Rhodope Mountains rewilding area in southeastern Bulgaria. The birds had been additionally measured, biologically sampled and fitted with rings and wing tags.
This implies 29 griffon vultures and 26 black vultures have now been tagged as a part of the continued LIFE Vultures project, which has been working to assist the restoration and enlargement of the black and griffon vulture populations within the Rhodope Mountains of Bulgaria and Greece since 2016.
Paying testomony to undertaking efforts, 95 griffon vulture pairs had been counted within the Rhodope Mountains rewilding space earlier this 12 months, up from a low of simply three nesting pairs in 1986.
Whereas grownup black and griffon vultures are usually regarded as sedentary birds, the information collected by the Rhodope Mountains rewilding staff has proven that griffon vultures from Bulgaria and black vultures from Greece frequently cross the Bulgarian-Greek border looking for meals.
Much more outstanding than this are the massive journeys that tagged juveniles of each species have been proven to make. Juvenile griffon vultures frequently voyage as far as the Middle East, whereas in 2017 a juvenile griffon vulture flew over 5,700 km from the Rhodope Mountains to South Sudan.
Younger black vultures have additionally been recognized to wander enormous distances. In March a tagged juvenile named “Chrysoula” made a 3200-kilometre, 17-day journey over the Balkans, whereas in 2018 “Helena” travelled nearly 2200 kilometres in 11 days, flying immediately over each the Southern Carpathians rewilding area in Romania and the Rhodope Mountains rewilding space in Bulgaria.
The Rewilding Rhodopes web site encompasses a live vulture tracker displaying the (virtually) actual time routes of birds tagged as a part of the LIFE Vulture undertaking.
It’s thought that the nomadic behaviour displayed by younger black and griffon vultures could also be a results of their intuition to disperse, as they search out different places to colonise.
GPS transmitters have proven that younger vultures are sometimes extremely susceptible, particularly throughout their wanderings, with round 70% failing to succeed in maturity.
Because the starting of 2019 three black vultures within the Greek a part of the Rhodope Mountains have been discovered poisoned, whereas in mid-April a griffon vulture fitted with a transmitter was additionally discovered useless.
The five-year LIFE Vultures undertaking was developed by Rewilding Europe, in collaboration with the Rewilding Rhodopes Foundation, the Bulgarian Society for the Protection of Birds(BSPB), WWF Greece, the Vulture Conservation Foundation and the Hellenic Ornithological Society/BirdLife Greece.
Specializing in the Rhodope Mountains rewilding space in Bulgaria, in addition to a bit of the Rhodope Mountains in northern Greece, the goal of the undertaking is to assist the restoration and additional enlargement of the black and griffon vulture populations on this a part of the Balkans, primarily by enhancing pure prey availability, and by lowering mortality by way of elements comparable to poaching, poisoning and collisons with energy strains.
