Owing to satellite monitoring of the birds released in the Life Bonelli Project, we know that some of them ventured within the territory of the only spawning pair formed in the Tramuntana Mountains of Mallorca (the female Bel and the male Vent). It is a risky manoeuvre since the Bonelli’s Eagles defend tenaciously their territory against others of their species. In this respect, direct observations are much more interesting than the “cold” GPS tracking since they help us to know more about the behaviour of the birds. Here are two examples.
