World-class migration monitoring at Batumi soars or falls with your support!
Dear raptor enthusiast,
Over the past years we have been getting more and more surprised reactions from volunteers and visitors about the fact that Batumi Raptor Count is a 100% volunteer-based organisation. “How can it be that this world-class migration count is run by people in their spare time?” And they are right to be surprised! The fact of the matter is that our monitoring work is of extraordinary quality, delivering unique data to detect trends in the abundance, demography and migration timing of otherwise poorly known raptor populations. Our open and transparent data collection and sharing procedures far exceed common standards for bird observatories worldwide. At the same time we have provided numerous young people from around the world with life-changing and career-defining experiences in raptor research and conservation. Our migration counts and physical presence in Georgia also serve as the platform from which we have run numerous education and conservation projects in the past.
For thirteen years we have managed to keep the counts going without big crowdfunding efforts. However, despite the fact that long-term monitoring is critical to understand how bird populations are faring in our rapidly changing world, structural funding for monitoring schemes such as ours is very hard, if not impossible, to find. Until now we have been able to get by on grassroots conservation grants, support from loyal sponsors like Swarovski Optik and OSME, t-shirt sales, donations from ecotourism operators and members of the public, and last but not least: thousands of hours of unpaid work by 395 volunteers from dozens of countries. However, times are a changin, and now that BRC is entering its 14th year of continued monitoring efforts the moment has come to tell you loud and clear: the Batumi Raptor Count soars or falls with your support. The best way to ensure our world-class monitoring work can continue is to donate generously to our charitable cause!
Asking for money is never fun. But we believe we have earned our place as a respectable, reliable, and resilient organisation that helps make the world a better place for raptors. So here is the deal: we need 20.000EUR per year to run our autumn count, and the only way we have left to get it is by asking for your support. If we do not get the required amount before June 2022, there will not be a raptor count in Georgia next autumn. However, given our large international base of supporters and followers, we believe it should be possible to raise this amount through an annual crowdfunding campaign, the first of which will run from Dec 2021 through May 2022.
On the crowdfunding page you will find more details on what the money will be used for exactly. On average, 200EUR funds one day of high-quality counts. With 130EUR you fund a one-week participation of a young Georgian conservationist. So what are you waiting for? Please, help us circulate this message widely, and let’s get the funds we need asap. The sooner we get our budgets together, the better our team can focus on organizing a high-quality count, producing important research, and organising valuable education and conservation work in parallel to the counts, instead of wasting our time competing with other conservation groups for small grants. Your donation makes a massive difference to us, and you know we’ll use it wisely!
Warm wishes,
Batumi Raptor Count team
Falconers: friends or foes in raptor research and conservation?
Over the years Batumi Raptor Count has been able to piece together an accurate picture of the causes and consequences of raptor shooting in Georgia: a widespread but illegal practice that poses a clear and urgent threat to numerous species. The impact and drivers of traditional falconers, however, have long remained a bit of a blind spot in our work. To help change this, and to investigate whether a constructive alliance can be forged with ethical falconers, long-time BRC team members Dries Engelen and Wouter Vansteelant teamed up with Gizo Seskuria and Nika Budagashvili of the Georgian branch of Fauna & Flora International last autumn.

Supported by an INNO-fund of WWF Netherlands, our team spent about three weeks visiting several known falconry hot-spots across western Georgia, from Gonio to Poti and Bandza. We conducted informal, but in-depth interviews with 20 falconers about their motivations and practises, thereby scouting for particularly conservation-minded individuals with whom we could potentially start research collaborations. Our hope was to find around 5 motivated individuals to be trained in raptor ringing, as a first step towards a more ambitious project in which we want to trap and tag Sparrowhawks with GPS-transmitters. By involving falconers in research through ringing, and by using state-of-the-art tracking technology, we hope to increase their awareness and appreciation of the raptor species in their nets, and eventually become conservation allies in the fight against illegal hunting.
Despite a relatively short period, the project yielded a lot of new insights into the current state of Georgian falconry and its developments over the last 25 years. While most falconers find it important to keep the tradition alive and enjoy the thrill of trapping, training the hawks and competing with friends, very few still use their hawks to hunt quail. There are also concerning reports of increasing illegal traffic in hawks and large falcons (Peregrine, Saker) from Georgia to Turkey and the Arabian peninsula. At the same time, we strengthened our relationship with two young falconers who participated in BRC and FFI projects before and who have recently started university studies in ecology (Giorgi and Ioane). We also teamed up with their master-falconer, Levan Duduchava, who was by far the most frank and open falconer we have met on our trip, and someone with an incredible species knowledge.
Ringing hawks turned out to be more challenging, as the weather conditions were often against us. Nevertheless, over a total of 9 days we managed to trap, ring and measure 6 male and 49 female Eurasian Sparrowhawks and 2 Levant Sparrowhawks. This already provides interesting patterns in body measurements, such as a tendency for adults to have higher and less variable weights than juveniles. One young female that was ringed just before being released after her 2nd day in captivity turned out to have probably lost a huge amount of weight, raising concerns about whether such birds are in fact able to survive upon release.
Over the coming months we will be writing up our findings and perspectives on the current state of migration-based falconry in Georgia, and we’ll also be applying for small grants to fund GPS-trackers for Sparrowhawk research in autumn 2022. Whether and how this can all lead to a larger or longer-term alliance with falconers is still a large open question. The only certainty we have is that doing nothing will change nothing. So we are keeping an open but critical mind. At the very least we hope to further support Ioane and Giorgi in their formation as young ecologists, and to become enthusiastic ambassadors for raptor research and conservation in Georgia.
Update: Moult study of Batumi raptors
The Batumi Raptor Count has done extraordinary raptor migration monitoring for years, but apart from all the migration data we have been collecting for so long, the bottleneck offers another interesting possibility. With the help of our volunteers with photography equipment, we are able to study the moult of the Batumi raptors.
Moult is a broad field of study which is often neglected due to logistical challenges. Moult studies require comprehensive data that is generally obtained via access to large numbers of captured birds or museum skins to gain detailed information. This is particularly difficult for birds of prey. Moult studies can give insights into difficult to study aspects of bird ecology via interactions with other life events. These studies are therefore an important application in conservation driven research. Both migration and breeding of raptors (or birds in general) have been studied extensively, but moult is a broad field where fundamental insights can still be made. To the best of our knowledge only one study has used digital photography to study moult patterns of migrant raptors at a geographical bottleneck, revealing a strong positive effect of autumn passage date on moult progression of Marsh Harriers migrating through Italy (Strait of Messina). Adult female marsh harriers showed a more extended moult and later timing of migration than adult males (Ramírez & Panuccio, 2019).

As you know, the Batumi bottleneck offers access to a great number of birds that can be photographed up close, and there are always generous counters (or tourists) who are willing to share their raptor photos with us.
And that is exactly what we have been doing. Since the 2019 autumn count we have systematically collected all the photographs from counters who were willing to share them for research purposes. This means that we have several hundreds of GB’s of photos available for a moult study and we have already started collecting moult data from the photos. Collecting enough data and analysing this takes a lot of time and effort, but we hope to be able to publish our first results in 2022.

The aim of this study is to use digital photography at a globally important raptor migration bottleneck to quantify moult progression in a wide range of migrant raptors, and to test the association of moult strategies with species-specific traits (evolutionary lineage, migratory traits) and individual traits such as age, sex and timing of passage within species. Expected outcomes of this study are variation within genera (in relation with individual traits). Some examples: species that migrate later have more advanced moult than others. Individual traits can show us that females have moulted more feathers than males, immature birds also show more moulted feathers than adults. Furthermore short-distance migrants have more moulted feathers than long-distance migrants and partial migrants show more variation in their moult extent.
We will continue collecting photos from our counters in the upcoming seasons, so we can continue to build towards a large dataset for moult study.
