I stepped up to the second small opening in the line of willows to the west of the north end of the settling ponds and pished, hoping for a vagrant passerine as the sun was first warming the vegetation. Soon I heard a Yellow-Warbler-like chip note, looked up, and got binoculars on a warbler just 7-8 m away that appeared to be a Blackburnian Warbler. However, I soon lost it as it disappeared westward, without being able to be completely sure. For the next 45 minutes or so I kept watch from the edge of the parking lot on the SW side of the willows, occasionally playing Eastern Screech Owl audio softly. This brought two Yellow Warblers in but nothing else. However, soon after I played audio of Blackburnian Warbler chip notes, the focal bird chipped twice and moved into view to my left. I subsequently was able to study it and try for photographs and video as it foraged actively in the sunlit willows (sometimes down to eye level but mostly behind leaves) for the next half an hour, always at the west end of the willows nearest the public restrooms. During this time, I posted an alert on WhatsApp and OBOL, and Eric and Hannah from Cannon Beach dashed over and were able to view and photograph the bird as well, along with a handful of casual birders/passersby visiting Cannon Beach for the day. As the photos and videos show, the bird was a New World warbler with a dull yellowish supercilium set against an olive crown and an olive triangular auricular patch. It had a heavily streaked back, bright white wingbars on a dark wing, pinkish base to the lower mandible, fairly bright white belly and undertail coverts, and distinct blackish streaks generously along the flanks and sides of the lower breast. The throat and upper breast were a soft but somewhat glowing yellow, and at certain angles the yellow of the upper breast showed an orangeish hue, suggestive of (and diagnostic for) Blackburnian even when it is faint. The tail seemed short (shorter than a Townsend’s, for instance), and the retrices from below showed mostly white with thin curved outer edges of black. The chip notes (inferred to be the bird; I did not actually see it call) to my ear sounded similar to the chip notes of Yellow Warbler. If accepted by the OBRC, this would be only the 16th record of Blackburnian Warbler for the state of Oregon. It would be the first record for Clatsop County; the majority of previous records have been from Harney County.
