Satellite-tracked Hungarian Saker (Falco cherrug) in N Spain
Mátyás Prommer has commented in the Raptor Biology yahoogroup the sighting of a juvenile Saker from
‘As some of you may be aware we are carrying out a four-year satellite-tracking project in order to study juvenile dispersal of Sakers in
However, not all of them did that. The most interesting move has been done by 'Piros' a 1cy female from West-Hungary! She made it to
Now it will be interesting to see where she goes now. Will she make it to
and look for Piros (feel free to check other birds as well)!’

On 30th July the bird crossed the border around to be radio located at Vall de Camprodón, Ripollés, Girona at 13h. It flew SW to the San Ramón – Calaf area at Segarra county, Lleida, an area of extensive plains and cereal agriculture where it remained that night. During its second day in Spain, it left Lleida province to head S for the Montblanc area, Conca de Barberà, Tarragona where it was located at 10 AM but it continued flying this time SW, through the coastal sierras to the Ebro river basin around Flix and Ascó villages, Ribera d’Ebre, Tarragona (13 hours). It continued this time Eastwards, entering the core of
On the 1st of August the bird was located at a bit NE of the steppe area, around Cariñena. Again on the move it was heading NE to the limit of Navarra and La Rioja communities and around 13h it was near Alfaro and Peralta. Again an open near-steppic cerealist area. The last up-to-date record was from 19h when Piros was heading NW within Navarra and it was in a wide area around Olite and Tafalla, which is also a credited area for Lesser Kestrels (Falco naumanni) within Navarra region. Pitillas lagoon observers might have a chance of having an encounter with this travelling falcon if he has decided to stay in this open countryside region? It may well be the case since the bird has favoured rather open habitat to travel across avoiding large forested areas or rocky mountains.
Significance of the record
Besides the Mátyás Prommer comment on the possibility of westwards vagrancy of Saker from the Carpathian basin and the biological significance of the whole project including their conservation implications, this record proves that not all Sakers (a common species in falconry) –nor Lanners (Falco biarmicus) I’d add- seen out of their breeding ranges are necessarily escapes or falconry birds.

Within 2009 tagged birds in this LIFE project, this is the only having flight westwards, with the rest having moved around
There is a sole previous accepted record of Saker in
In case of acceptance, this record would be the first proven case of natural vagrancy of the species in
On 5th August the bird had moved deeper into W Spain and lingered between Burgos and León provinces! It entered within Burgos province on 4.8 afternoon and spent the night there, near Burgos city at Villalonquéjar. On the 5th it continued W to Tierra de Campos and into Palencia province (contributed by Alfonso Rodrigo).
15th August update
In the locations from 14th August, Piros the saker is more or less staying in the wide area known as Tierra de Campos, within Valladolid province. The wide area would be between Becilla de Valderaduey and Villalón de Campos, near Villacid de Campos. It has been moving around the wide area always returning to a same spot. See a map below. A good chance for would-be observers?

Juan Sagardia located on 24.8.2009 the bird and photographed it around the location of the 14.8.2009, at Castilla León community. It's the first sighting of Piros in Spain by any observer. See some stunning photos in Juan Sagardia's blog here.
After visiting Portugal briefly on 30-31.8, the bird returned to the wide area Zamora-Valladolid-Palencia where it has stayed over 15 days. On 2.9.2009 it was relocated again at Palencia by Juan Sagardía and Antonio Ceballos. They have collaborated with the Hungarian LIFE team in the monitoring of the staying of this bird in our country.

Resumen: Halcón Sacre radiomarcado en Hungría en España. Piros, una hembra de primer año marcada con un emisor vía satélite en el NW de Hungría el 3 de Junio de 2009 entró en España por los Pirineos de Girona, Catalunya, el 30 de Julio sobre el medio día. Ha viajado por las provincias de Girona, Lleida, Tarragona, Zaragoza y La Rioja-Navarra donde permanecía en la zona estépica de la zona media el 1 de Agosto. Luego siguió hacia el oeste, pasando por Burgos y Palencia. Ninguno de los otros nueve sacres marcados ha ido hacia el oeste. Se trataría de la primera prueba fehaciente de que no todos los sacres que se ven en el oeste de Europa son procedentes de escapes de cetrería sino que la posibilidad, probada en este caso, de una divagancia natural existe. Se ha podido fotografiar el 24.8.2009. Visitó Portugal el 30-31.8 pero volvió a Castilla, donde fue fotografiado el 2.9 en Palencia. De homologarse la cita la especie pasaría a estar en la categoría A de la lista de las aves de España.
