I saw this bird briefly at the spot (north of Blossom Hill Rd on the Guadalupe River) where a Tennessee Warbler has been seen recently. I got these five shots of it, all showing only partial views. I noticed at the time what seemed to be white rear underparts, but didn't make any other observations of the bird -- too busy trying to get it in the camera! Looking at the pictures, the head markings seem weak -- faint supercilium and eyeline. Is this the Tennessee Warbler? Here for comparison is an Orange-crowned Warbler from the same location, same morning: http://upload.pbase.com/image/68160949 UPDATE: Knowledgeable observers tell me this is definitely a gray-type Orange-crowned Warbler.
