BUFF-BREASTED SANDPIPER IN LOS CANCHALES

On 25 September 2012 a juv Buff-Breasted Sandpiper (Tryngites subruficollis) was spotted at Los Canchales reservoir (Badajoz) by Jesús Solana, Antonio Núñez Ossorio and Joaquín Vázquez. This is the fourth Extremadura record and the first in the province of Badajoz.


As for the other Buff-Breasted Sandpiper found at Portaje reservoir (Cáceres) on 13 September [link], the bird was seen again on 20 and 22 but then wasn't found on a visit on 25 September. On the 22nd it was seen and photographed by Antonio and Julio Ceballos (bottom photo). As it happens, curiously enough, the Buff-Breasted Sandpiper's generic name has just been changed in the British List drawn up by BOURC. Its new name is Calidris subruficollis, so it is now included in the same genus as the Ruff (Calidris pugnax). More grist to the mill of nomenclature controversies...

BUFF-BREASTED SANDPIPER: THREE AND COUNTING

 A juvenile Buff-Breasted Sandpiper (Tryngites subruficollis) was spotted on the morning of 13 September 2012 by Sergio Mayordomo at Portaje Reservoir in Cáceres (top photo). It was feeding on one of the reservoir banks on newly sprouted grass in the company of migrant Yellow Wagtails. At midday it was seen again by Eva Palacios and Miguel Ángel Muñoz (bottom photo).

This is the third record for the species in Extremadura, all made successively in the last three years (Valdecañas, October 2010; Galisteo, October 2011; and Portaje, September 2012). All were juveniles seen in the province of Cáceres. The sightings are too new to have been officially accepted by the rarities committee as yet, but in all three cases there are photographs that prove the identification beyond a shadow of a doubt.

This vagrant American wader is now turning up more regularly in Spain with 45 accepted records involving 49 birds up to 2009. This figures will no doubt rise in future reports because there were considerable influxes of this species in both 2010 and 2011, with 25-35 birds recorded each year. In 2012, so far, there have been at least two sightings in August and another on the same day of 13 September in Vilafáfila (Zamora). Paradoxically, this increase of records in Spain does not at all tally with the specie's trend as a whole, since its status has now been downgraded by the IUCN to "Near Threatened" (NT).

EXTREMADURA CORMORANT COUNT 2012


A Spain-wide Cormorant (Phalacrocorax carbo) count was carried out in summer 2012. The provisional results for Extremadura, while awaiting publication of the overall data, are as follows.

Three colonies were found with a total of 651 occupied nests. The biggest colony, in La Serena reservoir, was visited twice. It comprises 619 nests in two clusters, the main one with 614 nests on half-sunken Holm Oaks and the other only 2 km away with 5 nests on Eucalyptus. The other two colonies found seem to be new, or at least unrecorded hitherto. One was at Alange reservoir, where a 23-nest Eucalyptus colony was found by chance on 12/07/12 (upper photograph; by Ángel Sánchez). The other new colony was at Alqueva reservoir, again on half-sunken Holm Oaks, with 9 nests counted on three visits from May to June. [Other post on Cormorant in Extremadura]


The Extremadura Cormorant trend is clearly upwards, with an exponential increase in only 10 years. Barring the one-off nest in Valuengo reservoir found in 1993 (Prieta and Mayordomo, 2012), the first Extremadura colony formed in La Serena reservoir in 2002. This colony grew from 10 pioneering pairs in 2002 to 102 in 2007 and 341 in 2011 (including 13 in Córdoba and one in Ciudad Real; Piñeiro, 2011) and 619 by 2012. Unless the final census results prove otherwise, this could well turn out to be Spain's biggest colony today. In 2007 there was a national breeding wildfowl count, including the Cormorant(Palomino and Molina, 2009). The published result included three Extremadura colonies, the abovementioned one in La Serena and another two at River Guadiana in Valdetorres and at Valuengo reservoir. There is however no trustworthy information on these two ostensible colonies, with no indications of actual or recent nesting in 2011 or 2012. The prudent option is therefore to rule them out. In 2012 two new colonies were found, once more on big reservoirs of the Badajoz basin, and regional figures have doubled in a single year. [Other blog entries on the Cormorant in Extremadura]


Collaborators. The La Serena and Alange colonies were found by the Junta de Extremadura: Ángel Sánchez, Domingo Rivera, Sergio Pérez, Miguel Ángel Sánchez, Fermín Sierra, Demetrio Vázquez, Irene Rodríguez, Sandra Blanco, José Manuel Rama and José María Castaño. The Alqueva colony was covered by Luis R. Hernández Díaz-Ambrona and Juan Carlos Panigua (SEO/BirdLife volunteers).
