A whirl of black birds moves noisily along the edge of the mountain wall before landing on a heath covered with juniper bushes. Dozens of them in a joyful rumpus, the Yellow billed Choughs feed on the berries left in winter. Real acrobats, they are capable of breathtaking aerial demonstrations. This ease of flight enables them to travel daily from places of high altitude spending the night there in holes in the rocks, to the bottoms of the valleys where they often find food near to the villages. This small member of the Corvidae species is protected and is on the regional red list because its natural habitat is very localized.
