Pied Flycatchers

Someone please tell me if I am wrong but I think this may be the cock on the left and the hen on the right. We have never ever seen these birds before. A couple of weeks ago I put up this nesting box never expecting it to attract any attention this year. Imagine my surprise this evening while gazing out the window to see this pair fly in and out several times like as if they are inspecting the real estate. 
In the meantime we have blue tits nesting out the back in the older box.
