From Fig. 1 of the article: camera trapping placed on perching sites (adults: female and male 5+ years old and 8 years old, respectively).
Fig. 2 from the article: Trend data for Bonelli's eagles marked as recruited as territorial birds in the study population. a) Proportion of recruited individuals per year in relation to the total population; b) average age of recruited individuals per year.
Fig. 4 from the article: Apparent survival of territorial Bonelli's eagles in the studied population in relation to the best-supported models that included individual experience and sex.
New paper: a 19-year photographic capture–recapture study shows Bonelli’s eagles have high survival, especially experienced females, with improved recruitment and earlier breeding over time
