During the last six years, the Egyptian vulture population in Bulgaria experienced sharp decline by 39%, reaching 35 pairs in 2008 from 57 in 2003. In 2007, the species was uplisted to “Endangered” in the IUCN Red Data List, following large decline throughout its whole range.

Amongst the most severe threats to the Egyptian vulture population in the breeding grounds are the various accidents of poisoning, occurring after consumption of contaminated or poisoned carcasses.
The project aims to ensure the long-term conservation of the globally endangered Egyptian vulture, by implementing priority activities from the National species action plan for 2009 and 2010. The specific objectives are:

1) to support Egyptian vulture survival during the breeding period;
2) to reveal unknown threatening factors, regarding food contamination and consecutive chemicals accumulation in the unfledged juveniles;
3) to develop human capacity to continue the conservation work on Egyptian vulture in the future;
4) to raise the public awareness on the subject among the local communities.

Activity 1: Supplementary feeding: Additional food will be supplied once a week to the population in the Roussenski Lom area. 2-3 kg of fresh meat will be disposed on cliffs (within 300-500 meters of the nests), which are easily accessible for the vultures and out of reach of ground carnivores. This will increase the adult survival and the breeding success.

Activity 2: Toxicology sampling and colour ringing of juveniles: Blood samples and eye, throat and cloacae secretion will be taken from 10 unfledged juveniles and sent for analysis to the Natural History Museum in Madrid. The juveniles will be ringed with plastic colour rings. It is necessary to reveal unknown limiting factors and guide future conservation activities.

Activity 3: Training and involvement of local team members: Six local team members (biology students) will be trained in monitoring, toxicology sampling, ringing and community education. These people will come from different regions where vulture subpopulations exist. It will secure the availability of local experts in the future.

Activity 4: Local communities and authorities education: Meetings with village mayors, Regional Inspectors of Environment, hunters and other local groups, will be carried out to explain the need for the species conservation and promote cooperation.

In conclusion the project will support the species existence during the breeding period, reveal unknown threats, implement local community education and involvement and finally improve the capacity of our project team to continue the conservation work in the future.

Project Update: August 2009

Ten unfledged juvenile Egyptian vultures were toxicology sampled and ringed in July and early August 2009 under project activity 2.

Blood samples were taken to study the contamination levels of heavy metals, antibiotics, pesticides and diseases. Secretions from eye, throat and cloaci were also taken for studying the prevalence of bacterial and fungal infections.

We ringed the birds with permanent plastic ring that will allow future identification in the wild. The yearly carrying out of this activity, combined with subsequent good monitoring will allow us to study the individual lifetime reproductive success, breeding territories and mate changes, immature and natal dispersal, obtain survival estimates, identify the birds during migration and wintering etc. In this way we will also gain invaluable information for the future planning and execution of the conservation measures.

The action was broadcasted on the most popular Bulgarian television:

The participants were Ivaylo Angelov, Vladimir Dobrev, Dobromir Dobrev, Volen Arkumarev, Tsvetomira Yotsova and Nikolay Terziev.

Project Update: December 2009

In October 2009, 1000 copies of a 2010 calendar that promotes the conservation of the Egyptian vulture were printed.

During October-November 2009, more than 500 copies were distributed in about 110 villages and towns in the distribution range of the species in Bulgaria. Most of the calendars were distributed among the most important target groups: village majors, livestock owners, shops and public pubs, schools, cultural clubs, municipalities, hunting associations, foresters etc. During the activity we always presented and discussed the threats for the species, the danger of its soon extinction from the country and the activities being undertaken. Topics as how everybody can help were also debated.

Besides the educational importance, one of the biggest benefits from the activity is that we discovered local people (mainly shepherds) who know the species very well and are even voluntarily helping it through disposing of animal carcasses on accessible places and through awareness rising. The idea for establishing of local caretakers of every particular nest emerged.

We will continue with this activity in January and February 2010 and we plan to visit additional about 100 villages mainly in the Eastern Rhodopes.

We are looking forward the return of the vultures and the start of the supplementary feeding activity in 2010.

As part of another project for the species tomorrow two of my colleagues and me are heading towards Ethiopia and Djibouti for 20 days to study the reasons for the expected high mortality in the wintering areas of the species.

Project Update: January 2010

On the BSPB website you can find information for the Egyptian Vulture expedition which we made to Ethiopia. http://bspb.org/show2.php?id=1408&menu_id=33

The results were very good but it seems that a small number of the Bulgarian vultures winter there, so they probably are in Chad and Sudan, as once in 2001 the only satellite tracked bird wintered in Chad.

Project Update: March 2010

April is coming and the Egyptian vultures will soon return to Bulgaria. We are preparing for the start of the supplementary feeding in Bulgaria. If everything is alright until the end of April and beginning of May 2010 I will have another update for the website this time for the supplementary feeding programme.

Project Update: June 2010

In 2010, BSPB started an experimentation of a new methodology for supplementary feeding for the population of the Egyptian vulture in Bulgaria. The novelty in this method is the use of small quantities of food (up to 1 kg) in specially chosen places. The feeding is necessary to provide extra amount of safe food, which will contribute to increase the nest success and to decrease the risk of poisoning. The feeding proved to be extremely important and decisive factor for the continuation of the breeding of one pair of Egyptian vulture, where the male disappeared 5 days before hatching but the female continued to incubate and hatched one chick. In the subsequent time, already more than 20 days, the survival and growth of the chick was fully dependent of the provided food by us.

In May and April 2010 a total of 30 artificial feedings have been done. In 19 out of 22 feedings with subsequent monitoring, the vultures accepted the food.
