A bold treecreeper, creeping up a tree outside my parents' house at lunchtime today - the first one I have ever seen.
While I'm here, am I allowed to mention yesterday's sightings? Peregrine, sparrowhawk, teal, pintail, gadwall, mallard, mute swans, cormorants, g.c.grebe, peewits galore (hurrah!), shelduck, shoveller, pochard, tufted duck, coot, moorhen, men in camouflage with telephoto lenses longer than my arm, busts of Sir Peter Scott etc etc. But alas no bitterns.
