Lanky medium-sized Tyrannus with large black bill, dark eyes, mostly pale gray head, dark eyeline, slightly but more extensively paler throat, greenish upper breast, lemon yellow belly and undertail coverts, dull greenish back, dark wing coverts with pale edges on all feathers, and thinner (for a kingbird) tail of medium length that was entirely dark and slightly forked. The legs and feet were dark. Silent today. Photos tba"

Swainson's Thrush (Catharus ustulatus) (1)
- Reported Nov 10, 2026 08:05 by Ben Kolstad
- Cerro Alto Campground, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.7491446&<ll...>,-120.7491446
- Checklist: https://ebird.org/checklist/S409557898
- Comments: "Was pretty sure I saw one in the field but missed it with my camera. Was surprised when Merlin's photo review declared my Hermit Thrush photo to be a Swainson's. I think it's wrong."

Cassin's Finch (Haemorhous cassinii) (1) CONFIRMED
- Reported Nov 10, 2026 07:00 by Kilian Hampl
- Pismo SB--Oceano Campground, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.6265268&<ll...>,-120.6265268
- Checklist: https://ebird.org/checklist/S409622576
- Comments: "**Very rare, irruptive. H/o. While on the peninsula I heard a single flyover passerine calling that I recognized almost immediately as a Cassin’s Finch, having seen and heard countless birds both as a yard bird in Oregon and in California (including this last Thursday on Mt. Pinos). The actual call that was heard was a distinctive husky three syllable “tee-dee-lip”. The bird sounded close enough to get an identifiable recording, but just as I was about to record a rather noisy family with three small children approached me asking what I was seeing. Needless to say I didn’t get that recording…"

Red Crossbill (Loxia curvirostra) (1) CONFIRMED
- Reported Nov 10, 2026 07:00 by Kilian Hampl
- Pismo SB--Oceano Campground, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.6265268&<ll...>,-120.6265268
- Checklist: https://ebird.org/checklist/S409622576
- Comments: "*Very rare, irruption year. 1-2, h/o flyover. While on the Norswing drive trail north of the main entrance I heard briefly what sounded like a single or possibly two Crossbills flying over giving “chewp-chewp-chewp” calls vaguely similar to the introductory notes of a wrentit song. I suspect that the calls I heard were representative of type 2, though without a recording to analyze I cannot be certain. Unfortunately there was too much traffic noise for any useful recording to be taken."

Savannah Sparrow (Large-billed) (Passerculus sandwichensis rostratus/atratus) (2)
- Reported Nov 10, 2026 08:02 by Erich N
- Morro Bay SP--Marina/Boardwalk Trail, San Luis Obispo, California

- Checklist: https://ebird.org/checklist/S409597596

Bullock's Oriole (Icterus bullockii) (1) CONFIRMED
- Reported Nov 09, 2026 11:30 by Kaaren Perry
- Morro Bay yard, San Luis Obispo, California

- Checklist: https://ebird.org/checklist/S409596517
- Media: 1 Photo
- Comments: "Bird was seen briefly moving from the interior of a Catalina Cherry as it passed through our yard. Medium sized oriole showing dark lores, faint post ocular stripe, black stripe on throat. Vivid orange upper breast fading to pale on lower breast and belly. Immature male"

Orange-crowned Warbler (Channel Is.) (Leiothlypis celata sordida) (1)
- Reported Nov 10, 2026 07:00 by Kilian Hampl
- Pismo SB--Oceano Campground, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.6265268&<ll...>,-120.6265268
- Checklist: https://ebird.org/checklist/S409622576
- Comments: "*Expected winterer in small numbers in south county; continuing bird seen well at the redstart nesting spot on the Norswing drive trail north of the main entrance. This was a large dusky OCWA with a large bill, greener supraloral, greener upper and paler lower eye arcs, diffusely streaked breast with a slight “vested” appearance, and slightly brighter green undertail coverts extensively streaked olive (&gt;50%). Heard giving thick lower-pitched metallic chip calls typical of this subspecies/type. Aware that sordida now intergrades with lutescens in southern California, but this was a straightforward sordida, at least from a phenotypic perspective. Photos tba, see media notes for additional comments."

Magnolia Warbler (Setophaga magnolia) (1)
- Reported Nov 10, 2026 07:00 by Kilian Hampl
- Pismo SB--Oceano Campground, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.6265268&<ll...>,-120.6265268
- Checklist: https://ebird.org/checklist/S409622576
- Comments: "**Very rare. One extraordinarily cooperative probable HY male seen well (at one point 3 feet from my head!) with a mixed flock near the Maintenance yard here: (35.112454, -120.627182) before eventually moving off with the flock back in the willows in the direction of the maintenance road. Medium-sized warbler with small grayish bill with fleshy base, dark eye, white eyering, mostly pale grayish crown and face with a little bit of white above the eye, bright saturated yellow throat, breast, and belly with reduced but distinct black blobby streaking on flanks and breast, bright white thighs, vent, and undertail coverts, blueish gray and green back with reduced but obvious black markings, uniformly pale-edged black wings with the exception of two bright white wingbars, mostly dark uppertail coverts, and a long tail that was mostly dark when folded and viewed from above and showed a white undertail with a very thick complete black tip, an undertail pattern unique to this species among North American wood warblers. I did not hear this bird vocalize to the best of my knowledge. Photos"

Palm Warbler (Setophaga palmarum) (1) CONFIRMED
- Reported Nov 09, 2026 08:41 by Eric Smith Jr.
- Turri Road, San Luis Obispo, California

- Checklist: https://ebird.org/checklist/S409619575
- Comments: "Facing away. Dusky olive back, yellow patch on the tail that was more dull golden colored than in YRWA. Bobbing tail constantly while perched in the anise. White supercilium visible when it turned its head toward us."

Yellow-rumped Warbler (Myrtle x Audubon's) (Setophaga coronata coronata x auduboni) (1) CONFIRMED
- Reported Nov 10, 2026 07:00 by Kilian Hampl
- Pismo SB--Oceano Campground, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.6265268&<ll...>,-120.6265268
- Checklist: https://ebird.org/checklist/S409622576
- Comments: "*Uncommon. One drab female (?) bird in mixed flock in willows on Norswing drive trail bordering Pier avenue here: (35.106814, -120.625903). Similar to a dull HY Audubon’s but with pale throat (duller and dirtier-looking than the brighter pale throat of Myrtle) extending around auriculars. Additionally there was no supercillium and it gave very odd, clearly intermediate chip calls. Tried for photos but flew across the lagoon before I could get any."
