(Description:) Field Marks and Identifying Characteristics:	As discussed above, the field marks for me were the color and color pattern, lack of wing bars, lack of orbital ring, and pale supercilium.
Song or call & method of delivery:	Silent
Behavior:	Stayed in a compact area while I observed, but jumped and flitted about in shrubbery and bare growth close to the ground.
Habitat:	This bird was in a wooded riparian-type area.
Similar species and how were they eliminated:	Eliminated Orange-crowned Warbler, also in the general area, which I heard. Head of the bird I recorded as a Tennessee Warbler was green with strong pale supercilium, unlike Orange-crowned Warbler which has a darkish eye-line, and this Tennessee Warbler had a pale gray belly, unlike OCWA. Nashville Warbler has a gray head and yellow belly and strong orbital ring. Eliminated Nashville Warbler. Virginia's Warbler is overall gray and yellow and has a strong orbital ring. This Tennessee Warbler had no orbital ring and was not yellow. Common Yellowthroat. Female has a duller greenish back and yellow to some degree on the underparts, which makes it very similar to the OCWA in appearance, but it does not have a strong pale supercilium like the TEWA. MacGillivray's Warbler is yellow underneath, gray hood and strong white eye-arcs, no supercilium. Was clearly not a MacGillivray's. Chestnut-sided Warbler is another warbler with a brighter green upperparts and pale gray underparts, however The Chestnut-sided Warbler has wing bars. Others: This bird had no streakiness anywhere and the contrast between the upperparts and underparts was striking.
Previous experience with this & similar species:	I have seen this species this Fall at Gilman Park in Fullerton, for extensive periods, along with many other birders in Orange County, and have learned its field markings and how to distinguish it from other warblers here which are more common and other warblers which have arrived in Orange County this Spring and are in the category of "rare." I have studied many of the photographs taken by my fellow birders during this period. The bird I saw looked pretty much identical to that bird.

Other observers who independently identified this bird:	I was alone, but I was told by a birder in the Red Rocks Audubon group which I encountered as they were returning from their walk that this bird was seen in the specific area where I then went and found the bird. I did not rely on the tipster's representation that the bird was a TEWA, because even experienced birders can be wrong. But since I had very recent experience with what has been an "event" bird in Orange County, I was able to recognize the bird as soon as I saw it and was able to study it.

Additional comments:	I am resubmitting this because I misspoke as to when I saw the Tennessee Warbler this year. I saw it this Fall, not "Spring."
