In Search of Owls

Yesterday evening we heard an owl hooting near the house, a tawny owl hoot.  Neighbours have seen a barn owl hunting over the field behind.  This evening we went out just before dusk to see if we could find any.  We met the farmer's wife who had watched the barn owl recently over the fields of Heath Farm, and then another birdwatcher who had seen or heard reports of short-eared owls and a barn owl over the fields on the path towards Therfield.  All good news, but we drew a blank, just got a good view of a buzzard.
