Note the undertail covert barring - black bars wider than white base. Also the underwing coverts are a rather uniform chocolate brown, as is the body.
Tail wholly dark except for a few small white spots on the outer 2 tail feathers. In my opinion this tail pattern is easily within the range of that seen in second winter smithsonianus (though of course this does not mean it is one).
Lovely dark greater coverts and solidly brown tertials. BUT I still cant get myself too exited - the head and upper breast are much more streaked and blotched, respectively, than can be tolerated. Also, I'd like plainer median coverts and scapulars. Despite being very dark, with a number of good looking features, it is not quite the full smithsonianus package.
