[TN-Bird] Mystery warbler

We get a fair number of 'confusing fall warblers'  in our yard each year.  The 
water feature we installed 6 years ago generally lets us get pretty good looks 
so that we can identify 99% of what shows up.  Today we had a visitor I do not 
recognize.  It may well be a first fall Kentucky warbler, but some of the field 
marks are absent.  I did manage to get a few pictures of the bird.   They can 
be seen at: http://www.birdnerds.com/Yardbirds/uknwarbler/index.htm

These are photos straight from the camera, not cropped or edited in any way.

The lack of yellow in the lores, supercilium, and around and behind the eyes 
bothers me.  The amount of black and gray above the eye is also bothersome.  A 
few of the pictures also show a brown crown patch.
