Large bird photobombs Swallow pics

Early this morning, whilst photographing the Parsonage Farm swallows settlling on the telegraph wires, this large bird flew slowly and effortlessly past. The swallows weren't at all concerned by it.

Following similar sightings reported on an earlier newspost, it is tempting to identify it as a White Tailed Eagle. (I will ask more knowledgeable people.)
