This bird is closely linked to the rocky walls, on which it nests and seeks nourishment.
During the spring and summer seasons, the rocks exposed to the north, cool and humid, at altitudes between 1300-1400 m and about 3000 m are preferred; in winter, on the contrary, the sunny walls are selected at altitudes below 1500 m; artefacts such as castles, towers, churches and dams are regularly visited during wintering and can sometimes be used as breeding sites. It feeds on small arthropods which it searches between the interstices of the rocks fluttering along the walls.
He builds the nest in crevasses of overhanging rock walls, often several tens of meters high. The female lays 3-4 eggs and hatches them for 18-20 days; juveniles stay in the nest for 3 or 4 weeks.
