Unbeknownst to each other I was there too - I parked at Gupton Farm, walked up to the ridge - and saw, like Richard, that the central and lower Corse areas were wet but birdless. However - the upstream area looked extensively flooded, right up to Corston Farm, so I cut my losses, returned to the car, and relocated to Castlemartin Church. Here things were a little better. When there is water, the upper Corse is favoured over the lower by wildfowl and waders. A flock of 16 greylags, 10 mallard, a single wigeon, 150 lapwing, 20 curlew and 3 golden plover plus gulls.
Sad to hear about the barn owl. Last winter a barn owl used the hide as a roost. Only the other day I was talking to Will the farmer at West/Court Farms (upper Corse area) who saw two individuals recently, so hopefully there are others. I too found a dead bird, a buzzard, waterlogged, filthy and and face down by the track - I had to flip it over to check it really was a buzzard. Natural causes most likely.
