I hard this bird whilst standing on Cresswell Pond causeway. I went back to the car park and out popped a fabulous Wood Warbler. Sadly the photos are a bit washed out and don't show the wonderful bright yellow throat.
Tere is a lot of variation in Stonechat colours but this is one of the darkest I've seen. Even black on the flanks and small white rump.
Sadly I haven't had time to look up all the plants. Will try and catch up later.
