Grey Wagtail for #BigGardenBirdwatch

Took the 'big' part of this literally, and joined the rest of Friends of Saughton Park for a collaborative birdwatch. About a dozen of us spread around the park, were by the yes hedges and got a nice range of hedgerow birds. Reckon we noted about 20 species altogether. However, my blip pick is from my way home, as I walked past the Water of Leith on my way out. I spotted a flash of yellow, and caught this very active grey wagtail - the first I've seen. It looks as though someone has been at it with a fluorescent yellow highlighter!
