"Conservation of the Bonelli's eagle" (© Roberto García-Roa | Spain).
The Bonelli's eagle (Aquila fasciata) is categorized as "Vulnerable" in Spain, a country that owns ≈60% of the natural populations of this species in Europe. Recent evidence suggests that Spanish populations might be suffering a decline as a consequence of diverse factors such as poisoning, electrocution, drowning episodes, or even the competition with other eagles. Importantly, not all of these factors are equally relevant, and the magnitude of the damage still remains unclear. To avoid the situation becomes worse, a global conservation project tries to not only track adult individuals, but to also to medicate chicks against trichomoniasis, a pathogen considered as one of the most important nestling mortality factor.
