male Reed Bunting
male Great Spotted Woodpecker
male Red-crested PochardAnother Swallow flew high over the lake (probably pressing on with its interrupted northward migration after yesterdays thunderstorm). Two species of Woodpecker were also about including 1♂ Great Spotted Woodpecker and a Green Woodpecker calling from the wood by the Colne Valley Trail. Back at Croxley Common Moor 1 Red Kite and 1♀ Kestrel flew over. Unfortunately I didn't manage to see the Grasshopper Warbler but hearing its song is probably the most interesting characteristic, despite this it was a good days birding, only next time I have to bring a puncture repair kit.
