Population justification: Around 200 breeding pairs, some of which include at least one subadult bird (Grupo de Trabajo Nacional del Aguila Imperial Ibérica, unpubl. data, A. Madroño in litt. 2005), so an estimate of 300-400 mature individuals is appropriate. This roughly equates to 450-600 individuals in total. |
|
Trend justification: The population has increased from as few as 30 pairs in the 1960s to 235 pairs in 2007 (Sánchez et al. 2008; González and Oria 2004; A. Madroño in litt. 2005). |
