AQUILA a-LIFE: Recovery of Bonelli's eagle in the Western Mediterranean

LIFE

  • A total of 45 specimens have been marked; 33 in the central area of Madrid and 12 in Andalusia.
  • Within the framework of the project, 5 breeding pairs of Bonelli’s eagle have been detected in the Community of Madrid, a milestone that has not happened since the early 80s.
  • A total of 7 chicks have flown in 2020, a key fact in the last 40 years.
  • It has been found that juveniles of the Andalusian population, the largest in the entire European Union, hardly leave this region.
  • The results of the project suggest that electrocution is the main cause of unnatural mortality.
  • It has been proven that interaction with the increasingly abundant golden eagle is also a relevant factor of juvenile mortality.

Bonelli’s eagle contributes to the balance of the ecosystem by controlling the population of the Bonelli’s eagle. The recovery of a top predator like this would be a benefit for both it and other species, especially threatened birds of prey, which will benefit by reducing the effect of electrocution, one of the most important causes of unnatural mortality today.

 

  • To reduce the risk of threats to Bonelli’s eagles and other birds due to electrocution in their natural range, both inside and outside protected areas.
  • Carry out a rigorous assessment of the conservation status of the Mediterranean metapopulation of Bonelli’s Eagle, assessing the effectiveness of the measures implemented for its recovery and defining the next steps with the participation of all relevant actors.
  • To develop awareness-raising actions in society towards the Bonelli’s eagle in particular, and birds of prey in general.

 

  • Surveillance of populations to know the use of space and threats to the species. To this end, 45 eagles have been tagged in Madrid and the central peninsular area, and Andalusia (chicks and territorial or rehabilitated adults), with GPS/GSM transmitters that will allow the download of data on the species.
  • Within the framework of the project, dissemination and communication actions have been carried out.

 

  • The monitoring of Bonelli’s eagle populations has made it possible to obtain data on the number and location of the most important areas of dispersal of the species in the Iberian Peninsula, as well as to know the patterns of movements between these populations and their greatest threats.
  • In just two years, 45 birds have been tagged in the central area of the peninsula and Andalusia. In addition, thanks to the releases in the central area, 5 new breeding pairs have been formed in the Community of Madrid, reaching 7 chicks flying in 2020. The AQUILA a-LIFE project will continue with threat flagging, monitoring and remediation until the end of 2022.
