(Description:) Basic Shape:	Warbler shape
(Description:) Overall Pattern:	Striking yellow cap; chestnut vertical bar in front of wing; light color body (white or light khaki; I remember thinking white when I first saw it flying). Lighter yellow or khaki color markings on wings. I thought not dark markings under wings when flying but I'm not sure.
(Description:) Bill Type:	I can't recall. Not distinct.
(Description:) Field Marks and Identifying Characteristics:	Based on my recollection when I first saw the bird flying from one branch to another thought the bird was white with dark markings under the wings. I then watched it for a two minute or so through my binoculars. Immediately following the sighting I wrote "Bright yellow crown, chestnut streak in front of wings, light coloring on wings". The yellow cap was sticking and cover all the cap, as I recall. It was the most striking feature. I notes the Chestnut colored bar, vertical if my memory is correct, in front of Wings.The wings when closed had yellow or khaki pale markings on wings. Not bright but distinct from the base color.
Song or call & method of delivery:	NA
Behavior:	Hoping/flying from one branch to another. Appeared to be feeding.
Habitat:	Wood mostly conifers, some scrubby bushes, scattered aspens. 15 to 20 feet or so from shore line.
Similar species and how were they eliminated:	I first compared to the golden crowned king let. The yellow crown was narrow in kinglet. The crown also did not change size. I didn't recall any black around the base of the crown. I recall the bird was larger. I then compared to the golden-winged warbler. This had a cap that looked like the bird I saw. The black on the face didn't seem familiar. It also lacks the Chestnut markings.

Additional comments:	I'm not 100% confident I have the correct identification correct but I do feel fairly confident. I'm certain about the features I quoted from my notes. I'd welcome a better recommendation though. I'm still a relatively new birder and have a lot to learn.
