No Sign of Barn Owls for 9 Days
We have not seen Mom or Dad visit the nest box for 9 days now. Barn Owls usually select a sheltered location to roost. They like to use an established favored site, which is then used for breeding. However it is likely that other suitable roosts exist in a bird's territory, which may cover up to a kilometer in any direction. This alternative roost site may have been discovered when the young were getting larger and the adults were unable to fit in the nest box. Barn Owls are not known to migrate and there is no evidence of migration established in most studies of marked individuals conducted in North America and Europe. The species remains resident in winter even at northern limits of their breeding range in the western Palearctic and no clear directional movement trends have been documented in Europe. Therefore, both Mom and Dad should be near by, and are likely roosting in a second location within the territory, either together or apart over the fall/winter months.
