The breeding territories or the dispersal areas of
juveniles suffer alterations derived from the human activity, which
make difficult or end up by disabling the presence of eagles.
If
these changes are punctual and reversible, they originate only the
defeat of the reproductive tasks during a breeding period, but if they
are serious and irreversible, they may affect the survival of the
eagles and thus induce to the definitive abandonment of the territories.
These alterations are a consequence of an untenable
territorial planning. The implantation of big infrastructures
(highways, quarries, wind parks...), the substitution of the
agricultural soil for industrial or residential, the disappearance of
the traditional uses for the agricultural and forest management, and
the untenable hunting planning have diminished the presence of
favourable nesting and hunting habitats and the plenty of the principal
preys of the eagles.
The changes in the habitats and territories often
imply that other rival species of Bonelli's Eagle, but more tolerant to
these alterations, could occupy its territories and compete in them,
turning into an added factor of pressure.
