Smallish warbler. White breast and belly. Black on head. Distinct chestnut patches on flanks. Foraging restlessly in tall poplars at south end of Swan Trestle, Lochside Trail. Singing constantly, chi-chipity-chi-chi Got several glimpses but could not get a picture. Either went silent or flew off after 10 minutes. Visited site again after about an hour. Bird was singing again. I could not spot it this time, but I managed to record its song. The song occurs once at about the 8 second mark of the clip and again right near the end.
