Relatively large warbler, moving in its own unique way through open trees. Moves slow but often, different from the other warblers around it. Pale yellow belly with fine black dots and strikes. Broken white eye-ring. Grey back. Seen by many. Probably one year male. Bird sang a few times (with long intervals), loud and clear, something like teee, teee, tee-tee.
