By 'strange' I mean not very successful!
Firstly a look at the Fisher Fleet in King's Lynn resulted in the Iceland Gull being absent so I cut my losses there are moved on to Snettisham where I also dipped the Pallid Harrier. The long walk south from the Shepherds Port carpark at least gave me some exercise! There was some consolation in the form of a nice Great White Egret on the saltmarsh with several Little Egrets, a Peregrine, Marsh Harriers, Common Buzzard and a couple of Rock Pipits, an extremely late Swallow north past the chalets, loads of Knot and Pink-feet on the walk but the main prizes of the day eluded me totally.
I even had another look at the Fisher Fleet before the long drive home but to no avail :-(
