Raptor migration watchsite at Bosporus

Pallid Harrier (circus macrourus)

Starting from 22nd September members of Milvus Group together with members of Istanbul Birdwatching Society are observing the migration of birds of prey at the Bosphorus strait, which is well known as one of the most important migration route for soaring birds in Europe. Observations are made at 4 countpoints simultaneously. The migration study camp will last till 13th October.

    Hi there, tomorrow I will go to Istanbul and hope to do some migration counting, can you tell the exact location of the best spot and whether there is a website with results of migration counts there? I have found some publications but no websites?

    kind regards
    Ps do you know the website for european migration counts: http://www.trektellen.nl ? originally a dutch site but now covering the whole of western Europe (Estland – gibraltar!)

    I was wondering if you will run a ringing station at the count site. I live in Canada and every spring and fall we band migrating raptors,coming and going to there breeding grounds. It is a great way to monitor the birds, and gives the opportunity for many foreign recoveries! With numbers like that passing by, the numbers ringed could be quite substantial…………
    I would be interested in sharing methods and results…….

    Hello Everybody!

    The first camp of the Milvus Group organized at the Bosphorus, Turkey has come to an end. I was informed that due to the bad weather the team decided to start the journey home today evening.

    However, I was also informed that yesterday there was a gorgeous day with probably more than 40.000 raptors (there were definitely more birds counted than that, but after elimination of double counts the number can decrease).

    The final number of birds counted yesterday as well as the overall totals for the camp will be uploaded on this website during the first days of the next week.

    Milvus Group would like to thank everybody who participated for their time and financial efforts, please remember that this year the camp was organized on a completely voluntary basis. In the years to come we would also like to base the camp on voluntary work, but we will try to secure funding which will enable us to provide good working conditions for everybody.

    If you would like to join our team in 2009, and participate in the activities of our raptor migration count in one of the most important migration bottle-neck sites of Europe, please send us a message on the marton.kelemen(et)milvus[dot]ro email address.

    All the best,

    Hi Again!
    The observation list is again updated.
    There are some good observations which are not mentioned on the list as the birds were not migrating. As I suppose that most of the visitors on this page are interested mainly in raptors I would mention only two observations of odd Eleonora’s Falcons as well as one sighting of an adult Lanner. Hopefully many more birds to come till the end of this week, when our 0 year experimental camp will close down.

    Hello everybody,
    Finally we managed to update the list containing the observations. Enjoy!
    There were some serious problems with regards the camping site in Istanbul, we were forced to leave the original camping site, to find a new place but without any electricity.
    That is why the update is coming so late!
    All the best,
    Marton Kelemen

    thank you for your e-mail. I’m sorry because I don’t speak english very well. I
    live near LYON (France). During autumn, september 1989 & 1991 I stayed to ISTANBUL and SARIYER for the migration. I would like come back for the migration of the black-stork and birds of preys during september 2009.

    Everybody who is interested to participate in the coming years in the activities of our Bosporus migration monitoring camp should send an email to my address (marton.kelemen(et)milvus.ro).
    The plans for the next year are not finalized yet, as we want to analyse the results of this (as we call it) 0 year. However in the next season according to our expectations, the camp will last longer and just as this time the work will be based mainly on voluntary work.
    In the following weeks a dedicated sub-page for the camp will be developed, on which regular news will be posted regarding our future plans. So please visit our site in the future for further details.
    All the best,
    Marton Kelemen
