Hola,
Parece que "Piros", la hembra de Falco cherrug radiomarcada en Hungría, que cruzó la Península durante el verano, ha desaparecido en Mauritania, o bien su emisor no funciona bien.
Reenvío este mensaje que me ha enviado Matyas Prommer.

Dear All
I had a sad news. After arriving at Mauritania (see maps) and being on a peninsula for a while, Piros' transmitter stopped working. The latest message was on 7th October without coordinates. There were only some error messages indicating that the GPS unit of the transmitter tried to locate the itself but it was timed out before succeeding. That can be for a number of reasons starting from the transmitter has become broken to the death of Piros (and the transmitter started to get covered by sand/water). I do not know.
Another interesting fact, that I have a data from a French literature about a juvenile Saker found dead in the water of Star Bay in Mauritania. When I first read it, I was doubting. However, the site is only a few kilometres away from the place where Piros disappeared and she crossed the same bay when she arrived in the area. Very interesting co-incidence and now I can believe that Sakers may visit the area.
Anyhow, this was only a short note to inform you about the latest and sad news. (Nevertheless, if you have anyone in the region who could check the site, please, advise me.)
Thank you again for your kind help earlier!
Best regards

Terminou a aventura...

"Dear Colleagues
Unfortunately, I have a sad news for you.
A few days ago - following of my request - an international team of biologists working with monk seals in Mauritania found the body of Piros on a peninsula on the northern part of the country (see 20.77100 -17.04467). When first seen, Piros seemed exhausted but the colleagues could not help her. She spent 8 days in the area before her signals disappeared. There is no explanation for her death since apparently there is plenty of food around: shorebirds, gulls and probably passerine migrants too. Nevertheless, the possibility of getting too tired after crossing the desert and not being able to hunt is not excluded. Further possibilities are: secondary poisoning (a large number of ships have been dismantled and sank in the area), some kind of disease or some unknown factor. It is a strange co-incidence, however that in 1979 a dead Saker was found by French ornithologists in Star Bay - just a few km north of the place where Piros has been found. This fact raises the question whether this phenomenon occurs from year to year, and this place is really a some kind of trap for Sakers; or it is really just a co-incidence and these two birds were found there co-incidently. This story shows again how little we know about our ecosystem and its 'elements'.
Certainly, it would be worth looking around there, however I can't see at the moment how we could get there in the close future.
The transmitter will be returned to us across Madrid with the help of a Spanish member of the team (to whom goes a great thanks).
Unfortunately, it seems that this is the end of the great story of Piros.
Thank you again for your invaluable help and I will inform you if there is any developments.
All the best
Matyas"

Re: Falco cherrug a caminho de Portugal!!!!!!!!!!!!!!!
Lembram-se do "Piros" que apareceu em Portugal em Agosto de 2009 e pernoitou no Sabugal sem que ninguém o tenha visto (foi detectado pelo seu transmissor de satélite)?
Pois bem, parece que vem outro sacre a caminho. Este chama-se "Eonka" e está agora nos Pirenéus Franceses. No início de Setembro estava na Alemanha, perto de Frankfurt; durante a segunda quinzena de Setembro atravessou a França toda em direcção a sudoeste e nas últimas semanas tem andado às voltas na zona de Toulouse.
Quem quiser acompanhar a situação deste falcão, pode ir a http://www.sakerlife.mme.hu/hu/gmap e escolher o indivíduo Eonka. Os dados mais recentes são de dia 10 de Outubro, mas é provável que em breve haja novos dados sobre a posição desta ave.

Re: Falco cherrug a caminho de Portugal!!!!!!!!!!!!!!!
Que rota migratória estranha, porque terá ido tão para Norte e depois descido?
Re: Falco cherrug a caminho de Portugal!!!!!!!!!!!!!!!
Pedro, esta espécie não é migradora de longa distância e provavelmente trata-se de movimentos dispersivos - neste casos, a trajectória é frequentemente errática.

Esta informação permite-me compreender um pouco melhor a triste história da "Piros". Parece-me, assim, bastante plausivel que a ave tenha feito um esforço superior às suas capacidades para chegar à Mauritânia, onde acabaria por morrer.

Graças ao seguimento por satélite, já foi possível saber que alguns falcões-sacre morrem electrocutados.
Embora a notícia seja triste, esta informação é importante na medida em que ajuda a compreender as causas da mortalidade destas aves.

A informação no site do projecto foi actualizada, o Eonka continua pela zona de Toulouse.

Re: Falco cherrug a caminho de Portugal!!!!!!!!!!!!!!!
O Eonka continua na zona de Toulouse mas mostra vontade de se dirigir para oeste. Será que vai entrar na Península?
Nota: o mapa anexo corresponde à situação em 5 de Novembro.
