Spent a few hours first thing to day on Salisbury Plain - no Merlins, no Hen Harriers.  Then spent a couple of hours wandering Bentley Woods - no Hawfinch, no Crossbills.  Spent the afternoon at Farlington Marshes - 2 Short Eared Owls eventually turned up at 16:00 once the sun had gone behind a cloud.  Mostly hunting way off in the distance.
