From the Rotherhithe and Beyond blog, with some lovely photos:
I spent a couple of pleasant hours locally in Rotherhithe this evening. And with the weekend of birding promise ahead, I was in a relaxed mood. So much so that I actually stood for several minutes, just listening to one of the Willow Warblers that currently occupy Russia Dock Woodland. Willow Warblers are just a passage migrant in Central London, so I only really hear the melancholy song for a few days each year.
