IL FALCO PELLEGRINO (Falco peregrinus) IN SICILIA
having doubled in number during the period 1978-2006, the population of the Peregrine Falcon Falco peregrinus living in Sicily currently seems to be stable, and has very probably reached the carrying capacity at the current ecological conditions of the insular ecosystems. A continuous standardized c...

having doubled in number during the period 1978-2006, the population of the Peregrine Falcon Falco peregrinus living in Sicily currently seems to be stable, and has very probably reached the carrying capacity at the current ecological conditions of the insular ecosystems.

The population is not randomly distributed, but rather it is concentrated in all the suitable habitats of the island, nesting in either small crags or large cliffs from sea level to 1,424 m asl; it is rarer in the north-eastern corner (Peloritani, Nebrodi, Aetna), with their mainly densely forested areas, and with fewer cliffs.
