RARE BIRDS IN EXTREMADURA 2010

The last volume of the Ardeola journal (vol. 59-2, December 2012) contains the report of the Spanish Rarities Committee for the year 2010. Of the approved 360 citations, only ten records were in Extremadura. Because in May 2010 this blog begun, most of them have more or less detailed posts. As a reminder they are presented below.

Pied-billed Grebe (Podylimbus podiceps). An indeterminate age male was seen in the Pond at Huerta de la Magdalena, Trujillo, Caceres, on 13, 14 and 15 May 2010 (Nigel Milbourne, John Barnet, Jack Willmott, Sid Massey, Jesus Porras and Pieter Vantieghem). This is the first sighting in the southern half of the peninsula and the only one in Extremadura. [See post and photography]

Marabou Stork (Leptotilos crumeniferus). A new record of a bird seen in October and November 2008 at Acehúche and Plasencia (Cáceres). The same individual was seen on February 28, 2009 by Manuel Perez Gonzalez at Portaje Reservoir (Cáceres). [See post and photography]

Rüppell's Vulture (Gyps rueppellii). Two observations have been approved, both in Monfragüe (Cáceres). One is for the year 2008: in Tietar Portilla an immature was observed on May 24, 2008 (Alfonso López and Ángela Molina). [See post and photography]. The second was in 2010: a second-year bird seen in the Salto del Gitano on 5 and 6 June 2010 (Sergio Mayordomo, Jesus Porras, Ernest Garcia, Manuel Garcia del Rey and others). [See post and photography].


Allen's Gallinule (Porphyrio alleni). This record has never been reported in this blog. An adult was picked up exhausted in the industrial area at Plasencia (Cáceres) on January 25, 2010 (Nuria Carrasco -author of photography, provided by Antonio Castellanos-). It was then transferred to the Centro de Recuperación de Los Hornos (Sierra de Fuentes, Cáceres), where it died the next day. This is the only report for Extremadura and the tenth in mainland Spain.

Pectoral Sandpiper (Calidris melanotos). Two juveniles were seen in the lagoon of Galisteo (Cáceres) on 17 to 19 September 2010 (Ricardo Montero, Sergio Mayordomo, Javier Prieta, Cesar Clemente, Eva Palacios, Miguel Ángel Muñoz and José Ramón Martín). This is the sixth sighting approved in Extremadura [View post and photographs]

Buff-breasted Sandpiper (Tryngites subruficollis). A juvenile was observed at Valdecañas Reservoir, El Gordo (Cáceres), on 15 October 2010 (Angel Sanchez). First record approved for Extremadura [View post and photographs]

Red-necked Phalarope (Phalaropus lobatus). A first winter bird was seen at Los Canchales Reservoir (Badajoz) on September 8, 2010 (Fernando Yuste and others). Possibly the same bird was seen again in Esparragalejo (Badajoz) on September 14, 2010 (José María Benítez). This record was treated only briefly in a monthly summary in this blog (September 2010). Photographs taken by José María Benítez can be seen in the following links: here and here.

Cackling Goose (Branta hutchinsii). An individual was seen on January 2, 2010 at Pela Navalvillar paddies, Badajoz (Antonio Ceballos), and Casas de Hitos and localities, Navalvillar Pela (Badajoz)-Madrigalejo (Cáceres), on 24 and 28 January 28 and February 1, 2010 (Local Group SEO-Cáceres). It is the only known record in mainland Spain. However, this species is currently included in the D (origin uncertain) in the list of birds of Spain, but in Europe there are known cases of natural arrivals. [See post and photography]

Saker Falcon (Falco cherrug). A record of a bird seen in La Serena, Badajoz, on April 22, 2007 (Jorgen Ballegaard and Alex Kirk Sand) has been approved. It is certainly of this species but had leashes so had escaped from captivity or falconry. So it goes to swell the list of Class E and is not considered a natural vagrant.

Apart from sightings approved, there have been others rejected. Specifically two Long-legged Buzzard (Buteo rufinus): the first in Belen, Trujillo (Cáceres), on 11 June 2010 and the second in Los Cerralbos, Trujillo (Cáceres), on 22 June 2010. This does not mean that they can not be of that species, especially as it is so difficult to identify this species safely. Here you can read a review of this species, including photographs of one of the rejected specimens. It also rejects a Common pelican (Pelecanus onocrotalus) seen in the Alqueva reservoir (Badajoz) on January 8, 2009. In this case, the description is considered insufficient, however, it is known that this birds corresponds to this species according to other accounts from the Spanish and Portuguese sides of this reservoir.

SAKER FALCON. NEW SPECIES FOR EXTREMADURA

 
Saker Falcon (Falco cherrug). Piros, a juvenile female born in Hungary and photographed in Palencia by Juan Sagardía (photo taken from his personal blog). 

The news is not exactly hot off the press but the Rarities Committee has just confirmed the presence of a Saker Falcon (Falco cherrug) in Extremadura in 2009, the second record ever for Spain, after the first in Cádiz back in 10.04.02, and the first ever for Extremadura. The curious fact in this particular case is that no one has knowingly seen this satellite-monitored individual in Extremadura territory: a young female called "Piros" tagged with a satellite transmitter on 03.06.09 in Hungary. Piros set off on her juvenile-dispersal journey on 25.07.09, passing through Croatia, Slovenia and, Italy to the south of the Alps (27.07.09) and the south coast of France. It entered Spain on 30.07.09 via Girona, then crossing Lleida, Tarragona, Zaragoza, Navarre and Burgos. It then settled down for a month and a half in Tierra de Campos (Palencia, Valladolid and Zamora) until mid September, barring a brief foray into Portugal (districts of Guarda and Castelo Branco) from 30 to 31.08.09. The following map, taken from the Rare Birds in Spain Blog, traces its movements within the Iberian Peninsula.


According to the detailed info of the website www.sakerlife.mme.hu its brief passage through Extremadura broke down as follows:
- 14.09.09. 10:00-12:00 hours, Palencia. 13:00-18:00 hours, near Puerto de Béjar (Salamanca). 19:00 hours, centre of Badajoz, where it spent the night.
- 15.09.09. 07:00 hours, still in the centre of Badajoz. 08:00-12:00 hours, moved southwards. 13:00-18:00 hours, north of Seville. 19:00 hours, Doñana.
- 16.09.09 and 17.09.09. Still in Doñana.
- 18.09.09, reached Cádiz. From 19 to 20.09.09 it crossed the Straits of Gibraltar and continued through Morocco, Western Sahara and Mauritania, where it was found dead, from unknown causes, shortly after 24.09.09.


The Saker Falcon is an open-country raptor whose range spreads from central Europe to China. Europe hosts a very threatened population, closely monitored since 2006. Up to 2010 47 were tagged (43 juveniles and 4 adults) with satellite transmitters. This research has shown that the adults stay put while the juveniles make dispersal journeys of varied length. Most stick to central Europe and a sizeable share shift eastwards to the Caucasus and Belarus, and southwards to Italy and above all Sicily. Only four birds reached Africa, one of them (Piros) passing through the Iberian Peninsula. Later on, another bird in 2011 moved to the west of France, brushing the Spanish Pyrenees but without actually crossing to the Spanish side.
