Long-tailed Duck (Clangula hyemalis) (1)
- Reported May 12, 2025 07:52 by Tom Edell
- Morro Rock Boardwalk Parking Lot, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.8592932&<ll...>,-120.8592932
- Checklist: https://ebird.org/checklist/S237018262
- Media: 4 Photos
- Comments: "Probably the continuing female again present on the inside of the sandspit across from the North T-Pier. Poor views, even with scope, and poorer photos due to distance. It was settled on the ground for most of the viewing but occasionally stood when approached by other birds. It appeared that more of the head was dark than when I last saw this bird with white on the face limited to a white wedge around the eye that thinned at the back. The bird was smaller than the adjacent Surf Scoter and had a small bill that I could not see well enough to determine the color. When it stood up and flapped its wings, it appeared to show a white band around the neck but no pale grayish scapular feathers. Otherwise the back and upper wings looked brown and the underparts were mainly white. (Photos)"

Summer Tanager (Piranga rubra) (1) CONFIRMED
- Reported May 12, 2025 07:50 by Nick & Jane
- Meadow Park--San Luis Obispo, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.6606531&<ll...>,-120.6606531
- Checklist: https://ebird.org/checklist/S237033671
- Media: 9 Photos, 1 Audio
- Comments: "Female. I was nearing the eastern section of park approximately here (35.2673681, -120.6607617) when I spotted a mustardy-colored tanager overhead in a pine, chewing on an insect.

The bird had no wingbars and a large mustardy bug-splattered bill. Its underside shone with a reddish-orange tinge, which was more prominent in the undertail coverts, though the tinge extended even up to the throat area. A little orange tinge could be seen on its wing/shoulder edge. And there were a few redder blotches. The lore line was dark, which made for a pale broken eyering, and cheeks greyish, but had no grey on its flanks. In fact, its upperparts were darker mustardy-green compared to the underside.

The bird then made several “piki” sounds before making some longer phrases of “pikituk” and then “pikituktuk.”

The bird flew eastward, though I soon came across it several minutes later in a deciduous tree. I saw this bird three times, with Roger showing up and spotting the bird on a third viewing in a bottlebrush tree opposite of Casa Diablo (eastern park home with feeders near park-side bird boxes). This was maybe 20-30 yards east of the coordinates and on the south-facing side of the trees. The second viewing was further east in large trees (sycamores?).

The bird wasn’t vocalizing on the second and third sightings.

*note regarding photos: The bird was in sunlight in one batch of photos, in the more reddish photos, the bird was in a shadowy and very bloomy red bottlebrush tree."
