Waxwings in willows

having not done any good with Waxwings this year I hobbled down to Messingham (another Badminton pulled muscle) but found the flock of 50 or so birds not very accommodating; the visits to the berry bush were fleeting and in the shade so I concentrated on trying to get shots of them eating the willow flowers but even in a fairly open willow they sat in the shade 99% of the time a very effective disguise as they were usually invisible!
