Question:I have a twitchy warbler that is light green in color. Can this be the pine warbler you were writing bout today a harbinger of spring?
Answer: Probably an Orange-crowned Warbler. Broken yellow eye-ring, diffuse streaking on the breast, yellow under the base of the tail (crissum), and lack of wingbars are indicative of Orange-crowned. Many of these warblers spend the winter here, so this is not likely a migrant. Its song is similar to the Pine Warbler, but the song is a steady trill that doesn't vary much in rhythm or pitch unlike the noticeably descending trill of a Pine Warbler.
