Me again, looking for ID on a bird I saw in my garden this morning. It was all brown, slightly larger than a robin. Quite compact in its body shape and had a paler (Light brownish) chest. I didn't think it was a wren because the tail was Longer, about the length of the body. The bird kept wagging its long brown tail up and down. The bird had a eye stripe that seemed darker than the brown head but it could have just been shadow. I saw it fly off, it had fast wingbeats flapping them at least twice a second.
I was thinking it was a Nightingale however according to my guide, Nightingales are summer visitors only. Could the recently hot weather have impacted movement or was it just a wren, a resident species. Or is it something completely different?
