Went to feed the doos last week in the high winds we had. 2 doos got out, glad it was a pair, they sat on the roof. Couple owe minutes later, the hen Peregrine came over trying to lift them from the roof above the house, glad they sat tight, managed to chase it away with a few bangs of the hands. After a few minutes before I shouted for them to come down, it came back again, couldn't put a rocket up as it would have scared the doos and then could have been trouble, they are on the hunt that's for sure.
