The empty nest didn’t stay empty for long. We only just had time to renovate the second owl box before this beautiful specimen arrived. He (or she, we can’t tell yet) is unlikely to be one of the youngsters who recently dispersed, may be one of the adults (though we haven’t seen them for months) or more likely a new owl seeking out its own territory.
A few days ago we left food out for the barn owls for the last time: if they didn’t come for it we knew they had dispersed. The food didn’t go to waste though: the next morning a greedy buzzard saw to that.
