WINTERING PALLID SWIFTS IN ALANGE. 2012-2013.

Author: Jesús Solana Ramos. Photography: Joaquin Vázquez. 

Since January 2010 has been observed the presence of wintering Pallid Swift (Apus pallidus) in Alange (Badajoz). In 2011-2012 it was found to remain during the entire winter season of at least eight individuals (read more). In 2012-2013 was done several visits between October 10, 2012 and March 7, 2013. The method was to wait in the square of the church from half an hour before to half hour after sunset. During this past winter has been observed at least two wintering individuals. Apart from these two birds, the latest swift recorded was on November 22, 2012 and the first on February 5, 2013 (5 birds seen by José Guerra and Marc Gálvez). Between these two dates, on five occasions were two swifts always entering the same hole in the front of the church.


A phenomenon in decline? If we consider the specific observations in early January 2010 and 2011 and compared them to the same dates in 2012 and 2013, we see a sharp decline in the number of birds recorded.



Other atypical wintering species. During the monitoring of pallid swifts was detected continued presence of 1-3 House Martin (Delichon urbicum) and one Red-rumped Swallow (Cecropis daurica) in December by M. Galvez and J. Guerra.

MORE THAN 100,000 CRANES IN EXTREMADURA (December 2012)


In December 2012 was carried on a common crane (Grus grus) census in Extremadura. As result, 95,282 cranes was counted. The coverage was almost complete, except for the region of La Serena and some roosts of Badajoz province. Estimating 6,000 cranes for no census areas, the final figure reached 101,000 cranes. The breakdown by areas is as follows: Zona Centro 63,207 individuals (62%), 22,292 Tagus basin (22%) and Guadiana basin 15,783 cranes (16%). Since a census of this scope is necessarily incomplete, it is possible that 120,000 cranes were present in Extremadura during winter 2012-2013. If we also consider that in February 2013 200,000 cranes have stopped at Gallocanta lagoon (Aragón), the figure of 120,000 cranes in Extremadura makes sense.


Two different methods have been used, on the one hand the traditional counting roosting, when cranes meet in wetlands to spend the night, and day counts at foraging areas. The latter has been used in the Zona Centro (Vegas Altas), one open agricultural region, with good visibility and extensive road network.

The comparison by sectors over the previous census of December 2007 (Prieta and del Moral, 2008) is shown in the table. For the whole of the region is estimated an increase of 20%. The Zona Centro grows very substantially (+65%), being the sole responsibility of the total increase. The Tagus basin remains very stable (+0'1%), offsetting rising sectors (Alagón and Almonte) those that decrease (Navalmoral and Cáceres). By contrast, the rest of the Guadiana basin, excluding La Serena, shows a drop of nearly 6,000 birds (-23%), mainly in the southern sectors of Alange and Azuaga. However, a census is a still image on a certain date and in the case of the crane wintering numbers can vary greatly between weeks in one place. Thus, after the census presented here, some sectors decreased (the Zona Centro declines slightly to 56,000 birds in January and February 2013), others areas were stable (Alagón) and other increased remarkably (Navalmoral rose by more than 4,000 cranes on February), to give some examples.

The evolution of the common crane population in Extremadura, as shown in the graph, remains positive with continued increases from the first data available in the 1980s. For the first time it has been found a figure of over 100,000 birds in the region, a value that duplicates the censuses conducted two decades ago (about 50,000 birds on average in 1989-1993 and 60,000 in 2001). All in accordance with the increase in Western Europe, where the current population is at least 300,000 cranes.

RARE GEESE IN EXTREMADURA. 2012-2013

The winter 2012-2013 has been excellent for wintering Greylag Goose (Anser anser) in Extremadura. This situation results in the arrival of geese scarce species, as it has been. Perhaps we are in the season with the highest number of geese observed in Extremadura and rare specimens seen for several months. Greylag apart, 26 individuals of six species of geese in eight locations are involved. Although these records have been published in our monthly summaries, it seems appropriate to group them into a single text. [See previous review on rare geese in Extremadura]


Bean Goose (Anser fabalis). Two individuals from two localities. The cumulative total is seven records and 13 birds.

An individual, possibly fabalis subspecies in the embalse de Borbollón (CC) between December 10, 2012 and January 23, 2013. Minimum 45 days. Cited on 10/12, 11/12, 15/12, 22/12, 17/01 and 23/01. Observers:
Goyo Naharro, Fernando Salas, Antonio Torrijo, Sergio Mayordomo, Ricardo Montero, Hugo Sánchez, César Clemente (photo), Javier Prieta, Javier Mahíllo, Eva Palacios, José Guerra y Marc Gálvez.

An individual of first winter in Moheda Alta, Navalvillar Pela (BA), on January 4, and February 2, 2013. Minimum 30 days. Observers: César Clemente, Pepe Guisado, Pilar Goñi, Sergio Mayordomo, Guillermo Mayor, Jaime Tolosa, José Guerra, Julio Merayo, Marc Gálvez y María José Valencia.

GREYLAG GOOSE IN EXTREMADURA. JANUARY 2013

 
The 2012-2013 winter has come to an end and it is time to talk about  the wintering birds in Extremadura. There are many who are interested after waterfowl, crane and cormorant censuses. I think its a good idea to start with the wintering greylag goose (Anser anser). The census of January 2013 recorded 23,173 individuals in Extremadura, almost triple that of January 2012 (8,020 birds). The graph shows the official census figures for January in the last 23 years. The interpretation must be made with caution, because of the large difference in census coverage over the years (very low in 2011 or 2009, for example, and several years without information). Still, there is a very clear upward trend, as already stated in a previous post. However, the distribution of the species is restricted to a few locations, the same as contained in the censuses of the early 1990s, over two decades ago.


The most prominent location is again Vegas Altas (#1), which has primarily rice stubble and, to a lesser extent, corn and other crops. Within the wide area available each year, most are concentrated in the eastern part of the county, it being too complicated to count scattered foraging areas and roosts (although in some seasons, as in 2007, there were more than 8,000 geese in Sierra Brava reservoir). On 14 and 15 January 2013, there were estimated 18,800 greylag geese, mostly at Logrosán municipality (15,000), and the rest between Madrigalejo (3000), Navalvillar de Pela (600) and other localities (200). This is the highest known, thanks to the good condition of the flooded rice fields. Quite the opposite during the dry winter before, when in January 2012, just over 4,000 geese were counted. The previous high dating back to January 2006, when there were 13,800 Greylag Geese.

Valdecañas reservoir (#2) also reached a peak in January 2013 (2,950 birds), perhaps helped by the low level of the reservoir and the large area of shoreline available. The geese were divided into two zones of the reservoir, a thousand in Bohonal de Ibor and two thousand in El Gordo-Peraleda de la Mata. Rare geese observations suggest little movement between the two sectors. Also, at the end of January the water level rose and some of the geese moved to the nearby pastures of Lugar Nuevo, Peraleda de la Mata. The highest numbers of greylag at Valdecañas were known to be 2250 birds in January 2012 and 1,875 in January 2005.

The remaining traditional greylag locations for winter populations harbored more modest numbers and in no case exceeded previous highs. So, in the reservoir of El Borbollón (#3) 186  were counted compared to the 458 of 2005. In Gabriel y Galán reservoir (#4) there were only 156 birds, half the maximum of 300 in 2000. Portaje reservoir (#5) had 206 geese in 2013, and the maximum was 293 in 2006. In Salor reservoir (#6), and nearby wetlands, there were only 56 individuals. The geese wintering in Llanos de Cáceres may vary location according to the years, the last two being focused on Valdesalor, when before they were at the ebmalse de Guadiloba, with the most in the region (250 birds in 2006). Los Canchales reservoir (#7) was the third location in importance in 2013, with 377 individuals, still far from the 900 of January 2000. Meanwhile, the Torremejía lagoons (#8) had 206 birds, well below the 1,050 peak of January 1999. This subpopulation occupies both these lagoons as Alange reservoir depending on water levels. Finally, the Llerena-Arroyoconejos reservoir (#7) showed a figure of 120 geese, far below the 1,100 in 2002. Although in other locations there can be geese in winter, they are not regular wintering areas. So in the January 2013 census, there were19 sites, and in January 2012, 21 sites. Other censuses, show more than 80 places with a greylag presence, in some cases it could be semi-domestic geese.
