Meeting in Roquefixade (France), a brief review

October 30th, 2016 / Comment
Roquefixade: a lot of sites for Short-toed Snake EaglesParticipants of the 4th Circaetus meeting

After Langeac (2004), Nadaillac (2008), and Florac (2012) the 4th Circaetus meeting took place in Roquefixade (the Ariège Department), on October 8th and 9th, 2016. Forty naturalists involved in the monitoring of the species, found themselves there at the invitation of Nature Midi-Pyrénées and LPO Mission Rapaces, to share their experience of the studies. The total number of the meeting participants was about fifty. The program illustrated the diversity of birders’ approaches within their means and goals.

September 12th, 2016 / Comment

As previously announced, the 4th meeting of the Short-toed Snake Eagle French national network in Roquefixade (the Ariège Department) /map/ is scheduled for October 8th and 9th, 2016. This conference is a meeting between passionate volunteers and not a scientific symposium. The program is not yet complete and it is still possible to propose communications. Any experience in monitoring Short-toed Eagles is of great interest and deserves to be shared.

Ringing of Short-toed Eagles in Hungary

August 31st, 2016 / Comment

SERFŐZŐ J, KOSSUTH L & others. 2016. The Zemplén and the Pilis MountainsThe program of ringing Short-toed Eagles is continuing in Hungary; 4 individuals were tagged this year:

3 chicks were ringed in the Zemplén Hills /map/ by István Béres (ringer), József Serfőző (climber), Zoltán Turny and Gábor Papp, nests were on Pinus sylvestris. Ring codes used: blue ring with white letters; A28, A29, A30.

1 chick was ringed in the Pilis Hills /map/ by Attila Feldhoffer (ringer), Vince Schwartz and Levente Kossuth (climber). There the pair has been nesting on oak (Quercus petraea). Ring code used: A41.

According to the Ringing Centre 83 Short-toed Eagles received rings up to date. Most of them were chicks tagged with aluminum rings in nests.

Ringing is usually carried out in mid-July. Totally, 24 individuals received colour-rings in Hungary: 20133; 20147; 201510; 20164.

The very first observation came this year from the Hortobágy region on July 21. The bird was ringed in the Bükk Hills on July 20, 2014. Besides two observations of aluminium ringed individuals, and a recovery from Syria in 2000 (a bird ringed in 1993 in Tokaj, part of the Zemplén Hills and caught in Syria in 1997 during spring migration) this year’s colour-ringed observation was the first when the bird could be identified. According to recommendations of Gábor Papp, local nature photographers are taking pictures of Short-toed Eagles even from a great distance to be able to check a ring presence and for filling a kind of database of their individual appearances.
