I am almost ashamed to post the heavily cropped shot of the bird on the right however have done so purely on the basis that it does portray the size of the bill and the supercilium, and no it is not a Redwing! To be honest the bird was a complete b****r all day disappearring for quite long spells and only showing at distances down to about 100 yards, although well enough through a scope. I only heard it call on a couple of occassions and I was on site all day bar an hour or so though not always by the birds field. The day got even better when Gordon Beck rocked up and mentioned that he had just seen a Dartford Warbler back down the road in the brambles by Lookers' Cottage. A quick mosy down quickly produced the harsh "chzzzzh" of a Dartford followed by it perching up on the brambles, and it later posed for the below average picture above.
Other sightings for the day comprised 8 Golden Plover, 3+ Marsh Harrier, 3+ Buzzard, 5+ SEO which as usual provided a quality performance towards the end of the day, ringtail Hen Harrier, Sparrowhawk, Raven, Kingfisher, Cettis', Water Rail, and numerous Kestrel, Fieldfare, and Redwing.
