Second photo of small bird by Thames.

i will guess a wheatear...but then am not always right so wait for the experts

Thanks, Linda. I don't think it was a wheatear but I am struggling to identify it at the moment.

Yes I agree, it looks like a rather bedraggled Wheatear.

Thanks for your help, Tony.
