I live in Central Scotland surrounded by farmland. This morning I saw a bird I have never seen before that I am aware of anyway It was about the size of between a Thrush and a Robin. mainly a fawn colour with I think darker wings. It was sitting on a fence stob and was bobbing up and down like a Wagtail but not quite as exaggerated. It sort of followed me along the road from fence post to fence post and when it flew it had a distinct white either rump of bits on it's wings that you didn't see when stationary. I of course did not have my phone with me to take a picture of it. I'm no ornithologist but know most of the more common birds around these parts but don't recognise this bird. I had a look through my Collins book of birds and nothing sprung out at me but then some of the drawings aren't that lifelike! Hope someone can come up with suggestions and I can look at pictures of them on the net. Thanks.
