Breeding: This bird lays 2-10 eggs in a nest built with plant remains and regurgitated pellets in attics of old houses, church ceilings and towers, lofts, and caves.

In the UFRA area: It is considered rare in these areas, as it was seen only once. Its occurrence was restricted to drainage ditches.
