Success for Imperial Eagle in Doñana

Doñana has managed to halt the mortality of the Spanish imperial eagle (Aquila adalberto). The annual number of chicks has tripled in the last three years from 3.5 to 10.5 chicks a year according to an article by scientists from CSIC in the ‘Journal of Applied Ecology’, thanks to a reduction in the use of poison in the areas surrounding Doñana. Between 1992 and 2004 there was a dramatic increase in annual adult mortality due to an increase in poisoning in hunting areas surrounding the park. “The use of poison against generalist predators accounted for more than 54% of the total number of breeding eagles found dead since 1990, increasing annual adult mortality from 6·07 to 12·01%.”

Here’s another great live webcam, this time on a Spanish imperial eagle’s nest in Cabañeros National Park (Ciudad Real). At the moment of posting this the chick is less one month old. The aim is to raise awareness of the importance of the conservation of the Spanish imperial eagle.

Spain currently has 234 pairs of imperial eagles, 34 more than in 2006, of which 73 are found in Castilla-La Mancha. The bird’s principal threats are poison and power lines; between 1990 and 2007 at least 95 birds were poisoned and a further 130 were electrocuted. The lack of rabbits is also a problem.

Success for Imperial Eagle in Doñana

Nine Spanish imperial eagle chicks have hatched this year in Doñana, following the nine of 2006. Only three chicks were born in 2005 due to the severe drought of that year, In the 1990s, an average of just three chicks were born a year. In addition to the 18 born in the last two years, five female chicks have been introduced by hacking. As with the lynx, work is being done on increasing Doñana’s rabbit population, the principal food source for the imperial eagle, with the aim of increasing the number of pairs (8 at present).
