Yellow wagtail?

Lovely walk in gorgeous sunshine this morning. Never mind spring, it felt like summer. Walked along a disused rail line converted to a cycle track. Urban but also a strip of green belt. I’ve seen deer and an egret here, heard woodpeckers and hoped that I’d spotted a dipper swooping over the stream. On closer examination of my photos, which were long distance, I think it was actually a yellow wagtail. I stand to be corrected of course!
