I spent a freezing cold 3hrs at Marton Mere this morning after I'd fininshed work. It was very quiet, I didn't see any other birders and only a couple of walkers.
The sun was shining and it was glorious morning - but no good for birding! By the time I'd walked the length of the mere to the east, my eyes were streaming and I had sun blindness - no point searching the tree tops here.
On the way back it was much better, with the sun behind me, it was actually quite warming...
