In the project LIFE07 NAT/BG/68 п during the winter 2012-2013 the sheep herds of FWFF and FWFF-Sofia (about 700 sheep) overwintered in Sakar. The aim is to be restored the ancient tradition of transhumance. This way valuable habitats are maintained in optimal condition to the benefit of threatened species.
Moderate grazing in certain seasons maintain and improves the habitat for the Imperial Eagle making its prey (mainly rodents) more abundant and accessible. When a dead animal from the herds appears it is also made available as a food for the eagles that are ready to scavenge especially in winter.
During the winter FWFF created suitable conditions for the sheep and shepherds. The lambing season is going well and has almost finished.
The pair of imperial eagles acknowledged the efforts of the project team and established its new nest just next to the sheep farm thus replicating the behaviour of their grand parents.
In the beggining of may 2013 about 1200 sheep and lambs is expected to move northwords to the seummer pastures of Central Balkan National Park, where they will mainain the habitat for susliks, imperial eagles, saker falcons and vultures.
On March 21-th, FWFF has compensated 6 farmers in the villages of Polena and Gorna Breznitsa in Kresna Gorge for their losses of livestock due to wolf attacks. Six goats and three sheep were given in order to stimulate the livestock breeders to take due measures to avoid depredation of their herds. This way it is believed the man/predator conflict will be mitigated and consequently no poison will be used to control predators. Finally this is something that supports the conservation of vultures in the area. See pictures from the event here.

The action is part of the “LIFE for Kresna Gorge” project LIFE11 NAT/BG/363 supported by the LIFE financial instrument of EU and co-financed by The Friends of Vienna Zoo, Austria and the Bioparc Zoo de Doue, France.
Today was proven the first laid egg of Griffon Vulture in Kotel Mountain for the last 50 years.
The birds were released by FWFF in Kotel Mountain in 2009. One of the birds is a French donated by Bioparc Zoo de Doue, while the other is spanish received within the Balkan Vulture Action Plan.
The actions of FWFF in Kotel Mountain are within the Vultures’ Return in Bulgaria Project supported by the LIFE financial instrument of EU and cofinancied by Frankfurt Zoological Society with Green Balkans as leading beneficiary.
In 2012 the same pair of Griffon Vulture bred for first time at about 60 km to the east in Kamchiyska Mountain probably pushed there from the severe winter conditions in Kotel Mountain at that time. The first breeding attempt was not successful, but we hope this year the pair to be succesful in Kotel Mountain. The hatching is expected in April 2013 and we will keep you informed about the developments.
A Griffon Vulture, released from the area of Kotel, Eastern Balkan Mountains, built its nest in the last remaining vulture colony in the Eastern Rhodopes.
Our colleagues from BSPB found the odd couple during the regular monitoring on the Griffon Vulture colony near Madzharovo, Eastern Rhodopes.
We recognized “our” bird by the blue wing tag with a orange “10” and the green PVC ring B19. This bird hatched in 2007 in the French Bioparc Zoo de Doue was released by Fund for Wild Flora and Fauna in 2009 from the special vulture adaptation aviary in Kotel.
At present the young family is building a nest on Kovan Kaya rock – one of the most important rocks for the Griffon Vultures in the Eastern Rhodopes.
This is the first confirmed case of a bird, released within the programme for restoring the vulture population on the Balkan Mountains, carried out by Green Balkans, FWFF and BPPS, settles in another, natural colony of the species.
Nobody likes to live in an empty block of flats, especially vultures. They are very social birds, which like to have neighbours. This is why, within the Vultures Return in Bulgaria Project, we always release a number of birds and keep some birds in the aviary, to imitate a natural colony and attract the ones we have released. Unfortunately our birds are too young and as every teenager, sometimes they like to stray a long way from home. Thus, in 2010 B19 left the area of Sliven and Kotel and found the natural colony of Griffon Vultures in the Eastern Rhodopes. There our bird fortunately found love. To our surprise, in the spring of 2011 and 2012 B19 managed to persuade the wild vulture to visit its “natal” site in the Balkan Mountains. Despite our hopes that they would turn into the second pair breeding in the area of Kotel, the instinct and experience of the wild vulture overweighed so the young pair returned back to the South, where BSPB reported a total of 56 pairs of Griffon Vultures in 2012.
We are wishing best of luck to the pair and are looking forward to seeing the “response” of the vultures, released in the Balkan Mountains within the LIFE08 NAT/BG/278 project.

Eight electric pylons dangerous for vultures in Kresna Gorge were equipped with perch discouragers.
In 2012 two Griffon Vultures were electrocuted on two of these 20 kV electric pylons. One of the birds was released within the project, while the other was a guest juvenile, probably originating from Croatia. Vultures native to Balkan Peninsula are a common sight while passing through the area on their migration. The Kresna Gorge became an important stopover for the Griffon Vultures on their migration, where they benefit from the feeding site and the company of the newly released vultures within the project.
FWFF with the assistance of “CEZ Electrodistribution” company implemented the equippment of some of the most dangerous pylons in the area. This way it is believed the area is now safe for birds of prey such as Griffon and Egyptian Vultures, Golden Eagle, Black and Red kites and others.
The European Ground Squirrel (Suslik) (Spermophilus citellus) is a Globally threatened species (IUCN Red List) that faced rapid decline in population in XX century. In Kotel Mountain the species disappeared in 1990-ies due to habitat degradation based on lack of grazing.
In 2011 the first 57 susliks were translaocated from the area of Sliven to the area of Urushki Skaly near Kotel and released in specially digged holes in the ground.

During the summer several recoveries of Griffon Vultures released by FWFF were reported from FYR of Macedonia, Greece and Eastern Rhodopi in Bulgaria. These are as follows:
Griffon Vultures released by FWFF in Kresna Gorge:
Red ring G28 – observed in the end of August 2011 at the feeding site Vitachevo in FYR of Macedonia (data from Emanuel Lisichanets / Association AQUILA). This bird is released in February 2010 and was not observed after the release. From the same area one more red ring – G?? was reported but the number was not seen.
Red ring G39 – observed on 14.10.2011 at the feeding site Studen Kladenets in Eastern Rhodopi, Bulgaria (reported by Ivailo Angelov/ BSPB- BirdLife Bulgaria)
Griffon Vultures released by FWFF in Kotel:
Green ring B19 – observed several times in Eastern Rhodopi. Last seen 16.10.2011 at the feeding site Studen Kladenets in Eastern Rhodopi, Bulgaria (reported by Ivailo Angelov/ BSPB- BirdLife Bulgaria)
Yellow ring K0M – observed several times in Eastern Rhodopi in Bulgaria and Dadia Greece. Seen 05.06.2011 at the feeding site Studen Kladenets in Eastern Rhodopi, Bulgaria (reported by Ivailo Angelov/ BSPB- BirdLife Bulgaria)
Yellow ring K0H – observed on 07.09.2011 by Volen Arkumarev/ BSPB at the feeding site Studen Kladenets in Eastern Rhodopi, Bulgaria (reported by Ivailo Angelov/ BSPB- BirdLife Bulgaria)
Blue ring F08 – observed in the end of August 2011 at the feeding site Vitachevo in FYR of Macedonia (data from Emanuel Lisichanets / Association AQUILA).
A young Griffon Vulture with wing-tag L02 was observed today (17.10.2011) at the feeding site in Kresna Gorge. Knowing the marking pattern used in the different countries, the bird is most probably marked in Israel. It is first time a Griffon Vulture marked in Israel to be observed in Kresna Gorge.
Today in total 7 Griffon Vultures and about 50 ravens were present at the feeding site in Kresna Gorge.
