I enjoyed the wander round - seeing Nuthatches everywhere is always fun (only 1 Treecreeper though). A Barn Owl flew through the trees, stopping briefly, and a Crossbill called overhead.

Didn't see any warblers but ventured to parts of the park I'd not been to before, including around the church...

There were plenty of ducks on the lake including counts of 118 Shoveler and 114 Tufted Duck. A Goldeneye was the only remotely noteworthy species though.

I could see lots of people on the road presumably looking for the Red-rumped Swallow (not seen all day) or at the Great White Egret (I couldn't see that from where I was). Among the Buzzards was this pale bird.

After Holkham I had a quick drive round a few likely spots looking for goose flocks, via fish & chips from The Mermaid at Burnham Market. Drew a complete blank on the geese.
