Chestnut-sided Warbler at Stow Lake

Nancy Palmer
 

Hi all, 
This morning, a chestnut-sided warbler was in a tree next to the concrete bridge on the north side of Stow Lake. It was chipping pretty loudly when I first came upon it. Ken Moy and Alan Hopkins joined and we had brief looks at it for about an hour. It stayed primarily in the canopy and looked as if it may have been an adult male in molt. 

See my ebird report with not-so-great photos here: 

Location: Dropped pin

Good birding!

The clear white/cream breast over a dark belly suggests a juvenile redtail. Adults generally have richer color on the breast, or if the have a very pale breast, will have spottier belly bands.

Saw this raptor on top of Strawberry Hill today in territorial dispute with two Red-tails. It was very dark. This is the best I could get. Apologies for quality but thought you might be able to help ID it from the very visible white chest. Harlan’s? Juvenile Or? Thank you.

Possible Bar Tailed Godwit at Heron’s Head

I photographed a Godwit at Heron’s Head that could possibly have been a Bar Tailed Godwit but the quality of the photo isn’t good enough to confirm. This was on August 1st - worth looking for if you’re out there - it was close to India Basin Park.

At about 10 am there were still thousands of Sooty Shearwaters off the Cliff House however they were far off shore. A few groups flew within binocular range. There were two Black Turnstones on the rocks. There were also Sooties off Pacheco. 

There is some  big golf thing this weekend at Lake Merced. Parking is challenging.

A few years ago I observed Sooty Shearwaters in Pacifica. They always came just before the sunsets.
Here's a video from last night.

Probably because of the strong overnight winds, there was not a single sooty to be seen this morning (8/5). I watched from the Cliff House at 8 and then moved to the Land’s End overlook at Mile Rock. Plenty of good birds, just nothing that could have been a shearwater.

Jaeger at Cliff House

No Shearwaters were visible from shore at the Cliff House this morning, but a PARASITIC JAEGER was harassing ELEGANT TERNS just beyond the rocks.

Big numbers of sooty shearwaters just offshore of Pacheco along Ocean beach. Streams moving south and north

Pelagic report - and Pelagic opportunities.

Hello all,

     My apologies for sending to various groups all at one time. But, this Saturday we did our first offshore pelagic of the season, from Half Moon Bay (San Mateo County). We have been doing trips to the Farallon Islands, but those have a limited time in deeper water, so I thought folks would be interested in knowing what is out there in the central CA offshore waters now. In short, it is pretty interesting and diverse with element suggesting this will be a warm water year with elements of the south moving north, and it is a season that is amazingly abundant as far as ocean productivity goes. We saw four species of storm-petrels, with groups of Ashy, and a scattering of Fork-tailed, Wilson’s, and Black storm-petrels. The Black are always of interest to us, since they do not always make it to our latitude, being dependent on what the conditions are like farther to the south. The weather was choppy, with a flatter ocean we would likely have found more and larger flocks of storm petrels. Where we found them, the water was warmer and more translucent, offshore water. We did find all three jaegers, as well as South Polar Skua which was early. There are good densities of Cassin’s Auklets out there, we found a gorgeous adult Tufted Puffin as well as the more expected alcids including Marbled Murrelets at the coast. Good numbers of Black-footed Albatross and nice densities of Pink-footed and Sooty shearwaters, earlier in the season Buller’s showed up (again early). Sabine’s Gulls are heading south, including our first juvenile of the season. Right now tens of thousands of Sooty Shearwaters are close to the beach in Half Moon Bay, this is a year with lots of anchovy, lots of krill and also squid. Abundance is the word. There is so much krill out there that the Cassin’s Auklets are trying to pull off a second brood due to the abundance of food. Meanwhile the Rhinoceros Auklets are feeding on 100% anchovy.

    The real oddity in the region has been the arrival of Bluefin tuna off Monterey, and Half Moon Bay. Big ones, averaging over 150 lbs each. This is not the norm, but is super exciting as it suggests northward movement of southern critters. Similarly, we had a good look at a Guadalupe Fur Seal offshore a little known marine mammal that seems to be found in warm water years. Warm offshore water has been peeking close to Monterey Bay recently. The combination of potential for some warm water birds offshore, and lots and lots of food closer to shore is great! We have consistently found awesome feeding congregations of Humpback Whales about 10 miles offshore. On this last trip we also found Fin Whale where the Cassin’s Auklets were (krill feeding we assume), and a super pod of hundreds and hundreds of Pacific White-sided Dolphins with a good number of the always dapper Northern Right Whale Dolphin. Blue Whale has been seen this year, but not this last weekend.

   It is early in the season and it is already pretty awesome offshore. I think this is going to be a great year for pelagics, and unfortunately not that many people are going to be able to enjoy it. We have a full schedule of trips out of Monterey and Half Moon Bay, Morro Bay is sold out, but are going with half or less of the boat capacity. On the trips we are encouraging people to be outside, in the breeze, social distance and to wear masks. As such, on the various trips we have done people have felt comfortable and safe. Key is to consider that the science clarifies that being outside, in the breeze, and in humid and salty air is a low risk situation. Crew are diligently disinfecting the boat, and ample sanitizer is available. One of the net benefits is a lot more room on the boats this year, and in Monterey keep in mind that the boats are much larger allowing for good spacing of birders and naturalists. Particularly this year, being out on the ocean is special, with nature abounding and away from the news, it is invigorating and good for the soul!

    Our next trip is an offshore Monterey trip on Aug 14, we are hoping to get into the real deep waters on this day and see if we can find some offshore murrelets and other goodies. The upcoming Farallon island trips are sold out. Our schedule of trips is here:

Shearwaters

Up to 50,000 Sooty Shearwaters are hanging out past Seal Rock at the Cliff House. Mostly they are just sitting on the water 3/4 to the horizon, or streaming south in small groups, they’re stretched out down Ocean Beach as well. If I stand here long enough with my camera maybe I will luck out and pick up a good bird or two in there.

Mountain Lake American Redstart continues

Daniel Scali
 

This bird requires a lot of patience at this point. I found him in the large cypress by the big cutout area in the usual Northeast corner. It still feels somewhere between possible and probable that there is a/are young skulking around in the riparian.

Until the next bird,

Migration stirrings - Western Wood Pewee, Western Tanager, Black-Headed Grosbeak

David Assmann
 

Saw my first small pulse of migration in the Presidio this morning, with a WESTERN WOOD PEWEE flycatching at Dragonfly Creek, a WESTERN TANAGER along the road behind the Park Police headquarters near Kobbe & Upton, and a BLACK-HEADED GROSBEAK in the Fort Scott Community Garden (which also had a PACIFIC SLOPE FLYCATCHER, probably a summering bird). Also had a BLACK TURNSTONE below Battery Godfrey. At Fort Mason, there were several WILSON'S WARBLERS and a flycatching PACIFIC-SLOPE FLYCATCHER in the garden.

SF weekend sightings

Tried for the yellow warbler and tailless Parula at Ft. Mason early Friday morning, but it was D-E-D dead. Just finches, and a subdued Mockingbird.

Saturday morning Crissy Lagoon was alive with so many herons, 300 Elegant Terns, four White Pelicans feeding, and a coyote at East Beach.

Today Lafayette Park delighted with a bright Wilson’s Warbler, Black Phoebe, and a two-barred, orange-mandibled, almond-eyed, tail-pumping Pacific Slope Flycatcher all in the same tree. Two Scrub Jays were yelling nearby. A Downy Woodpecker whinnied. They’re not rare but I don’t get to see them often in Lafayette Square. The usual orioles, Acorn Woodpeckers, parrots, and three red-tails were present too.

Hermit Warblers in Northwest SF

Daniel Scali
 

Holas,

I've had three in the last few days, located by the chip note. Listen to some audio and hopefully you'll find one of the dispersers too. It's actually the quiet space between chips that feels distinctive to me. Today's was at East Fort Miley near the golf course green. All have been catching insects (looked like little white gnats today) in Monterey Pines. My field guides had me convinced that I was seeing immature birds but the Internet says otherwise. All I know is they were not adult males.

Good listening,
Dan Scali, the Richmond SF

Seawatch -- Parasitic Jaeger movement, 8/1/20

Paul Saraceni
 

This morning I seawatched (7:25-10:10 AM) from the south end of the Great Highway.  Brisk/increasing W winds, gray overcast skies, choppy seas, incoming tide, very good visibility out to the horizon.        

The highlight was a good nearshore movement of PARASITIC JAEGERS (PAJAs).  Between 7:50 and 9:30 I observed at least 13 PAJAs, plus a 14th jaeger sp.  All were purposefully moving N and only 1 made a pass at an Elegant Tern, which were in view over the ocean in good numbers throughout the watch. The PAJAs primarily moved in small groups (2/4/4), with the remainder singles, and were a mix of adults and juvs., including one striking dark-morph individual.  The 14th jaeger sp. appeared to be a light-morph juv. which showed crisp, contrasty black-and-white barring on its undertail coverts, a clean white belly, and a whitish head.  Unfortunately I couldn't get any more detail from my distant photos.

Observations of local interest:

Western Grebe 1
Whimbrel 8
Marbled Godwit 1 (flying S with a Whimbrel)
Heermann's Gull 90 (including 1 juv.)
Glaucous-winged Gull 1 (continuing 1st-summer)
Glaucous-winged x Western Gull 1 ad.
Caspian Tern 5
Elegant Tern 220
Pigeon Guillemot 8 ad.
Com. Murre 28 (all adults)
Brandt's Cormorant 550
Pelagic Cormorant 5
Double-cr. Cormorant 40
Brown Pelican 280
Barn Swallow 1
