Pair of nuthatches building near Cromwell Bottom (EGP) - over canal at site of new timber houses.
They're in an old sycamore they've used before I think.
Chiff-chaff singing along there this morning.
Quite a few moorhens about generally down there. Council contractors have been destroying mink I believe, but a big one swam past me in the river - thought it was an otter for a moment!
