RE: Steller's Jays, might they be interior birds irrupting with the rest of the interior species we're seeing? We should be on the lookout for interior race birds. The frontalis and annectens subspecies differ in having a lighter blue on the back and underside and often blue extending up into the chest, grayer heads and backs and more extensive blue streaks on the forehead extending to the crown and in annectens white spots above the eye and whiter forehead streaks, among other subtle differences.

As part of the GGRO Hawkwatch team today, I enjoyed a strong flight day in the headlands. A good variety of raptors kept us busy, highlighted by 158 Broad-winged Hawks. We also had a good variety of passerines, highlighted by 3 calling Cassin’s Finches. Oddest sighting of the day for me was a tight flock of 7 Steller’s Jays flying just below the peak and slipping around to the south towards SF. I didn’t know that they moved regionally in groups like that.

Hey birders,
Right on time, 3 sparrow species arrived this morning at our house on Taylor Ln. Fox, Golden-crowned and White-crowned sparrows are now all here. I’ve always (20 years or so) found it interesting that whereas the GCs and Fox sparrows remain here until the last week of May, the WCs make brief appearances and then head a quarter mile to the east to the highest part of Taylor. Almost as though there’s an invisible barrier that keeps them from the eastern part of the road.
Good birding,
Mike Heffernon

Hi All,
Just wanted to get the word out since I haven't seen any other Bird
reports. This afternoon (9/21) saw a Yellow-green Vireo discovered by Mark
Butler (we think) by the now deserted houses. It was behind the last
building to the north where there is a single pine tree with its branches
laying on top of the roof of a shed.
A while later, David and I discovered 2 Baird's Sandpipers in the now,
almost dried-up large stock pond.
eBird report: eBird Checklist - 21 Sep 2026 - Pt. Reyes--Mendoza Ranch (B
Ranch) - 9 species (+1 other taxa) <https://ebird.org/checklist/S395116487>
Cheers,
Denise and David Hamilton

Subject: [northbaybirds] White-rumped Sandpiper and Hudsonian Godwit at Abbotts Lagoon, MRN |
Birders,
Cross-posting on the listserve that there is currently a juvenile Hudsonian Godwit hanging out on the west shore of Abbotts Lagoon. This bird was initially found on 9/12 by Derek Heins and Teale Fristoe, and subsequently refound in the morning of 9/14 by Eli Gross; having since been seen by many.
Yesterday, in addition to the continuing hudwit, Lucas Stephenson picked out an adult White-rumped Sandpiper in the growing peep flock on the north shore of the main lagoon. The bird was actively foraging and chasing juvenile Western Sandpipers, showing well for the many observers present. Eventually, the entire flock left the north shore of the main lagoon at dark, presumably to roost at a more protected spot on the main lagoon.
Good luck to anyone going for these birds, and congratulations to the original finders.

Subject: [northbaybirds] Selasphorus question (Occidental) |
Hello, birders. About a week ago I posted that I’d still been seeing Allen’s Hummers at and around our feeders. I also put Selasphorus in parentheses, as I’m not able to differentiate the two species without tail feathers being really evident. It was pointed out to me (very politely) that banded birds in September have proven to be mostly Rufous. So I have a question since I’ve seen these birds every day here in September, including today, the 15th (I’ve also seen them everyday since the last week of January): is it more likely that summer Allen’s are still lingering, perhaps because of the consistent food source; or is it more likely that migrating Rufous are taking a two week layover here? Or another explanation I haven’t thought of? Thanks in advance!

All,
Just the messenger. Photos of a Northern Wheatear that were taken today by Tom Nemeth at Point Reyes were recently posted to one of the regional bird groups. The bird was seen along the road, possibly around the coordinates below: 38.055287,-122.975480
If the bird sticks around, the best strategy to refind it may be to drive along the roads on the point scanning for birds on the fences next to the roads. Good luck to all chasing!

Good morning, birders. I’ve noticed for about a month, Allen’s hummers showing up on the Sonoma and Marin counties EBird rare bird alerts. Allen’s (Selasphorus) hummingbirds, which typically show up here the last week of January, are still present here on the Taylor Ln property on and around the feeders.
P.S. I miss how this listserve used to be utilized before EBird. It was always more descriptive, more personal. Alas.

There was a hy (female?) Mourning Warbler this morning at Rodeo Lagoon by “T1111” building here (37.8327046, -122.5277070). The bird was skulky but should be findable with patience. It calls a fair amount.
Best of luck to those who look it!

Subject: [northbaybirds] Backyard migrants in Napa |
Hi all,
I was planning on writing to you about backyard migrants in August -
particularly on Aug 27th when a Black-throated Gray Warbler showed up - our
3rd ever for our yard. We've constantly have had numerous Warbling Vireos
for 'dip baths' in our pond, and after missing out on them last year, we've
had quite a few Willow Flycatchers, sometimes seeing two at a time. I'm
thinking that some of them may actually stay for days at a time, since 2
years ago had one that showed up in the exact same spots, with the exact
same behaviors day after day, but this year not seeing anything to prove my
theory. Here is our check list if you'd like to see a few pictures: eBird
Checklist - 27 Aug 2026 - Backyard in Browns Valley, Napa - 22 species
<https://ebird.org/checklist/S387475282>
Other migrants include Wilson's and Yellow Warblers and Western Tanagers.
Today, Sept 1 is the actual reason I wanted to write - we had our
FIRST-Of-SEASON, WHITE-CROWNED SPARROW show up!! Looked back in the
records I have handy, and the earliest date of them arriving is Sept. 11.
What a surprise! It stayed around all morning, so will be interested to
see if it will be here again tomorrow. Also today, numerous Warbling Vireos
& 1 Willow Flycatcher, among the usual neighborhood birds. If you'd like
to see pics of the sparrow: eBird Checklist - 1 Sep 2026 - Backyard in
Browns Valley, Napa - 23 species <https://ebird.org/checklist/S388982733>
I'm truly amazed at what we get in our tiny backyard sometimes! My ongoing
advice to attract birds in your yard - have water features. Especially
this time of the year when it is so dry.
Happy migrant chasing to you all!
