Pelagic trip report - Sun Oct 4.

Alvaro Jaramillo
 

Hello all,

    Belated trip report, it has been a busy week. Yes, the season has turned, the late season birds are here. Overall the weather was a bit less amenable than the forecast had suggested, this meant we had to go a bit farther north into the weather to get offshore. It worked, and were able to drive south in a following sea through the Pioneer Canyon and then stayed off the continental shelf until we had to head back to port. We started off nicely with a pair of Marbled Murrelets close to shore as well as a couple of Parasitic Jaegers. Heading offshore I did get a very troubling feeling, there was little to nothing other than Common Murres as we went out, it took a long time to see a shearwater! In fact I saw an Ashy Storm-Petrel before I saw a Sooty Shearwater on this trip. But once we arrived at the continental shelf things began to sort out with Sooty, Pink-footed, and Buller’s shearwaters, Black-footed Albatross, as well as Rhinoceros and Cassin’s Auklets. It was a good day for Rhino Auklets, lots out there. Perhaps associated with these numbers we found two Tufted Puffins, a juvenile and a non-breeding adult; puffins at this time of year are very neat to see, so different from the summer. Heading south we picked up more Ashy Storm-Petrels, many Black Storm-Petrels and a Fork-tailed Storm-Petrel. South Polar Skua, two Long-tailed Jaegers (together) and Pomarine jaegers gave us the skua-jaeger “grand slam.” We picked up Blue Whales, which have been hard to find in central CA, we were able to share this information with Monterey Bay Whalewatch who are working with a TV/Film crew (BBC??) and they have been looking for Blue Whales, fortunately our magic spot worked for them a couple of days later and they were able to get some footage that we may see in a documentary in the future!

    On our way back more Buller’s Shearwaters showed up, and a flock of Sooty Shearwaters had an individual that was flying around with a darker underwing, a Short-tailed Shearwater. As well, about 10 miles offshore our first of the season Black-vented Shearwater showed up and a few more in the next 20 minutes or so. All jaegers and South Polar Skua, three species of storm-petrels and 5 species of shearwater, diversity is up! We have two spots on Oct 18, and a few more on the 24th remaining. https://www.alvarosadventures.com/pelagic-dates-2020.html

 

Also, I am doing a “Big Walk for Rhinoceros Auklets” a walking big day next week where I am asking for donations to Oikonos for the Año Nuevo Island project, restoring habitat and monitoring Rhinoceros and Cassin’s Auklets on the island. Hopefully I can break 110 species on foot power, and will likely walk about 20 miles assuming I survive!! Please donate – more details here:

Hi all,

There was a male Summer Tanage this afternoon in the big blooming Metrosideros eucalyptus by the bocce ball courts against a building in east Golden Gate Park. I watched it fly all the way over to the carousel just south of Robin Williams meadow.

Sparrows in numbers

Richard Bradus
 

Hi all

They're back! 

I had planned to take a look around the Simonds Loop this morning hoping that the Rock Wren or some other notable might still be about, but I never quite got there. Entering the Presidio from the Lyon St./Broadway gate, as I slowly descended through the woodland I walked right into a sparrow-palooza. First a couple of Golden-crowns, then White-crowns, more of both, Juncos (lots and lots of them), Towhee (at least six - the most I've ever seen in one place), a few Fox and Song, then just one swirling cavalcade of all of them, even a White-throated. Our winter regulars are arriving and, from the behavior I saw, many of them are famished and jumpy, feeding like crazy and chasing each other about for the spoils - and unfortunately skittish as well, scattering every time I took a step closer.

Also of some interest: a Creeper that briefly flew down and bathed in a small puddle from dripping fog below one of the pines - the first time I've ever seen a creeper on the ground. And a ?late Swainson's Thrush that flew out of the brush and posed nicely, but briefly, on a fallen log. Few Warblers (just one Yellow and three Townsend's) but Pygmy Nuthatches all over, a couple of early Kinglets and, following faint high pitched calls, a nice flock of Cedar Waxwings eating berries from trees just south of the back of the Simonds Loop houses. Looked like a good amount of activity around Logan's neighborhood (most of the above plus a bunch of Robins, Finches and the like) but I didn't venture any further.

Having chased a number of the "rarities" all of you have been so good at finding and reporting over the past couple of weeks (thank you!), it was nice to just stand and gawk at the spectacle of more typical local birds in good numbers and spirits. Don't overlook the pleasures of the common birds in our midst - they are endlessly entertaining and sometimes surprising. Especially in this stressful time, they are a balm for our souls.

Enjoy!

Fort Mason Northern Parula, Nashville Warbler

David Assmann
 

A NORTHERN PARULA was at Fort Mason this morning in a small tree southeast of the garden - don’t know if it is the same one that was seen until mid-September. A NASHVILLE WARBLER was in the Battery. The garden had 3 LINCOLN’S SPARROWS. 2 BONAPARTE’S GULLS flew by over the Bay, and two PEREGRINE FALCONS were going after ROCK PIGEONS in the piers. Still a number of YELLOW WARBLERS moving through and the number of YELLOW-RUMPED WARBLERS has increased dramatically to about 75.


Lake Merced, concrete bridge, interesting HY plumaged TOWA

Eddie Bartley
 

Left sunny and warm Potrero Hill mid afternoon excited to bird Lake Merced. A mile before we drove into a dense wall of fog. Right down to deck level too but it was mostly birdable and the colors really popped as long as the sky wasn't involved.

Big build up of coots and Ruddy Ducks now just north of the concrete bridge. We were sifting through the coots hoping for a moorhen when a Hatch-year (HY) Red-tail swooped at warp speed tight between us and a benched couple setting off an explosion of wings. Swing and a miss, gave us primates a healthy adrenalin rush too. Didn't find a moorhen but there was coot whose shield was bright yellow with burnt orange in the center so that was pretty cool.

Searching through the willows turned up the usual early October migrants: Warbling Vireo, Common Yellowthroat, Yellow, Yellow-rumped, Townsend's once we got to the east end conifers. RC Kinglet numbers are picking up as are Sooty Foxes. This is one of the only areas in SF where you can still see Brush Rabbits and supplementary feeding has made them tame, which is probably not a good thing for them. The remains of a young Brown Pelican are at the base of south side of the bridge, about 1/3 of the way from west, fairly well scavenged now. Curious how it ended up there.

One HY warbler feeding fairly high and inside a large pine gave us a start. Setophaga mask, looked orangish in face and upper breast but coloration was very limited barely extending past throat. Streaking in the flanks was almost obscure. Was feeding very energetically, moving quickly through the branches, difficult to get on. Thoughts drifted to Blackburnian but managed a couple of good snaps and the auricular pattern looked more like Townsend's. Never did get to see that back. Anyway, for anyone interested in confusing fall warbler shots I plunked one here: https://ebird.org/checklist/S74474844

We spent a short time over at Vista Grande too, lots of birds, especially in the upper canopy but the light had gotten so low, the only songbird species we added was a nice looking male Black-throated Gray for the day.

Happy Trails!

Re: Chimney Swifts

Brian Fitch
 

The conditions on Mt Davidson this morning were fascinating.  At my house in the city flats, it was 53 degrees and the car was drenched with fog precip, but on Mt D, a decent breeze was blowing from the east, it was dry away from the trees, and it was probably in the low 70's.  The strange aspect was not the inversion, but the thin layer of clarity between the surrounding fog below and the smoke above.  Judging from the Marin hills, there was possibly 300-400 feet of clear sky between these layers.

Nothing was flying when I arrived, so I made the circuit around the hill, finding only a few migrant species, but noting a large number of Purple Finches.  A flyby kestrel got my attention back on the sky, so I settled in on the northeastern shoulder for a watch.  Highlights over the next 2.5 hours included roughly 200 Band-tailed Pigeons, 50 Yellow-rumped Warblers, 110 Purple Finches, 50 Lesser Goldfinches, and 165 Pine Siskins.  There were several mixed flocks of finches and siskins, but most were in mono-flocks.  A pair of flyby Western Bluebirds was an uncommon sighting for here, and the only other raptors were a Sharpie and a TV, with nothing coming by after 11.  The only unusuals on the hill were both Red-breasted, a sapsucker and a nuthatch.  I left when the thin smoke layer lowered onto me around 11:45.

The Chimney Swifts came by well after ten, taking me by surprise as they approached through the eucs on the north slope.  They were flying eastward directly at me, then swerved toward the southeast over the ravine, over the saddle just a foot off the ground, and then soared out and downward over the south slope and out of sight.  They were close, in good light, and thankfully were of the darker variant of the species.  The field marks were already mentioned in the first letter, but again, the chaetura cigar shape was obvious, and the gray was steely, with no brownish tones that I could see.  Since I focused on a single bird, the closest, I am not sure if there were 3, but that was the peripheral impression I got.  So technically, they could have been of another species.  This is my second sighting in the city, both at Mt D, the first was in spring a few years ago.

Vista Grande today: Parula, Blackburnian

Jonah Benningfield
 

Birders,
Another exciting day at Vista Grande. Once again, I failed to get out all that early, but upon arriving at the Canal saw a Northern Parula in the same patch of flowering pittosporum where the Magnolia was yesterday.
In the eucalyptus trees behind the apartment complex (SW of the canal), a large mixed flock also included one Blackburnian Warbler, which eventually flew off into the golf course.
Also of note, Lucas Stephenson put me onto a Blackpoll Warbler he found at the Canal, a county lifer for me. Definitely seems like this area is a free-for-all of rare warblers right now, with better chances of discovering something new than refinding something old.

all the best,
Jonah B.

Thanks for the acronyms Jonah. Do they reference a previous thread so I can look up the birds full[er-] names from it?

Much obliged !

Hi folks, it's still here. 

On the east end of the trail, maybe 100 yards in. Photo of location. South side of the trail. 

Air ok, too, for now.

Re: Log Cabin Chestnut-sided

Richard Bradus
 

A few details:

After spending an hour and a half looping the Log Cabin Trail area with Nico Stuurman, seeing some nice birds but nothing rare, I decided to stick around and encountered Frank Merino while toiling away trying to get photos of an elusive gray-headed Orange-crowned Warbler. Like the rest of us, he had no luck with the Magnolia Warbler, but he had encountered a Chestnut-sided and managed to get some decent photos. So I made my way slowly back east along the trail, eventually re-encountering Cliff Yap (who had been there longer than me!) and he also had seen the Chestnut-sided, but indicated that it had flown north, perhaps toward the trees extending off JFK Drive.

It took more than another half-hour of craning my neck peering into this row of trees, but eventually a vocal gang of three Yellow Warblers appeared and - ta-da! - high in the canopy another, light bottomed bird, our suspect. Really difficult to see well as it stayed very high in the trees, gleaning almost non-stop and stubbornly most of the time in dense foliage, but I managed to see all the important details. It is a drab HY bird, showing just a bit of light green on the top of the (otherwise grayish) head and the back, a definite white eye ring and two very nice bright tan-yellow wing bars. It did not vocalize as far as I could tell (probably unwilling to compete with the louder Yellows!).

And - talk about good timing! - Joachim showed up just as I was sending out the initial email, so he got some decent looks as well. Also in the area were some more typical warblers (Townsend's mostly but also Wilson's and Orange-crowned and Yellow-rumps) plus a surprise Common Yellowthroat, Ruby-crowned Kinglets (FOF for me), many of the other regulars plus a Red-breasted Sapsucker.

So, some rather hard-earned rewards on what turned out to be an uncomfortably hot (and smokey) day.

Good luck! 
Be safe and mind the air quality.
