The decline of a population grullera.

Photography Our success does not transmit the reality of what is happening with this species in the wintering area. A place that should have a growing population, (as in all Extremadura and at the level of the Iberian Peninsula), It is already away from those 4000 birds that came to be here in December 2011, only in the reservoir roost Cuncos. The arrival of the Alqueva dam the site has brought new shallow banks, starting to become colonized with small nuclei roosts. This should favor an increase in their wintering population, but it's not like that. This year has reached maximum population peaks in the months of December and January, around a 400 cranes roost in Friegamuñoz (Alqueva) and a 1000 in the roost Cuncos.

Nail 30.000 hectares make up the feed zone in which adehesado intertwine with scrub bush, pastureland, encinar planted with cereal and wastelands. An exceptional place in this region, different from other areas of cultivated rice or corn feed and stubble. Depending on years, I guess that influences the number of cranes in one area or another. For me, what is obvious is the decline in recent years in an area that has everything you need to survive in winter. But I wonder ; Why those chickens who first came to this area now not become adult? Perhaps the bad experience in these rangelands, make in the coming years migration prefer other wintering areas.

Perhaps in this town living with these birds is not respectful, Here men and cranes do “hit it off”. That competition for food can be one of the reasons why the population is never quiet grullera. Persons engaged in agriculture, people who guard montanera pigs and so on, they are more busily than ever in the field shoo, a communal well that they believe is their property. I was born when the crane stopped being a game species, this is another thing that many hunters have not yet understood what I have seen on numerous occasions.

My fulfilled dream of photographing year after year, it now becomes a struggle to preserve this species, to continue enjoying hidden among them. It has also been the dream of many people who like cranes, They made a great trip, in this case to photograph or just observe them in their natural habitat. Their changing behavior, phonation your system and how aprender, their way of life…do I have “addiction to them”.

Another problem that exists in their conservation is habitat reduction due to changes in soil crops. In this case the area defined as pre-roost of the population grullera Cuncos is negatively affected by increased fruit crops. This transformation also negatively affects the steppe birds and the colony of lesser kestrels, It located in the very near to the area wirings.
