I took this picture a week or so back at the same time as my Willow Warbler picture, in the same tree as well. I actually thought it was another poor WW photo, but something kept nagging at me, so I checked it out in the ID forum. Jane came up trumps in the end with an almost identical pose of a spotfly.
It's ages since I'd seen a Spotted Flycatcher, so I'm well pleased. A good job I didn't delete it LOL.
