This must be a quite common bird and I've seen it before in previous years, probably also in springtime, but have failed twice now to identify it. (I'm also curious why that is, even with a search engine like WhatBird.) Perched this time atop a conifer. Loud song, rather small and quite slender, overall dark grayish(?) color, largely reddish neck and head (presumably on male), relatively long slender tail with a central notch (two lobes). Didn't have the best view or light, but no pattern easily visible on body (like stripes on a finch).
