Dear Birders,
Owing to the poor economics of growing organic rice this year, very little rice cultivation was done behind the Farm Center gate at the preserve. Consequently, both farmers prepped and flooded fields for birds this season. There has been lots of shorebird habitat behind the gate. Unfortunately, none of this was done on fields viewable by the general public. That is changing just now. Also unfortunately, some medical issues have kept me from checking these areas as often as desirable.
But a week ago I visited and before I got to the Tall Forest, it was apparent that shorebirds were present in good numbers, so I gave a miss to the woodlands. It took nearly four and a half hours to check all the flooded fields. The highlights on the 22nd of August were two semipalmated sandpipers west of the shack and a willet north of Oak Island. Somewhat lesser lights were a semipalmated plover, three short-billed dowitchers and two solitary sandpipers. Here's the list: white-faced ibis- 1850 (almost all gone by sunrise) black-necked stilt- 130 semipalmated plover- 1 killdeer- 25 least sandpiper- 290 semipalmated sandpiper- 2 western sandpiper- 170 peep sp.- 200 Wilson's snipe- 1 short-billed dowitcher- 3 long-billed dowitcher- 2050 solitary sandpiper- 2 lesser yellowlegs- 5 willet- 1 greater yellowlegs- 250 red-necked phalarope- 7 Wilson's phalarope- 1
Incidental passerines detected included a willow flycatcher, several lark sparrows, a yellow warbler and a lazuli bunting, all near the shack. Four river otters were at Garcia's swamp, which looks like it ought to have some Southeastern swamp warbler.
Today I did the same coverage, which took 45 minutes less time because several of the fields dried during the intervening week. Stilts, long-billed dowitchers and greater yellowlegs were present in much higher numbers than a week ago, and there were a few nice things among the common stuff. Here's what I turned up today: white-faced ibis- 1200 (again, gone by sunrise) black-necked stilt- 320 killdeer- 45 marbled godwit- 1 Baird's sandpiper- 2 least sandpiper- 180 western sandpiper- 55 short-billed dowitcher- 3 long-billed dowitcher- 4150 solitary sandpiper- 2 lesser yellowlegs- 6 greater yellowlegs- 450 red-necked phalarope- 14
The godwit conformed to my expectations for that species. It was gone when I drove back by five minutes later. They seldom stick around for long. That, the Baird's sandpipers and the solitary sandpipers were all in the area north of Oak Island.
Incidentals were fewer this morning, just a yellow warbler and three lark sparrows at the shack and a wrentit surprisingly singing from flooded willows at Garcia's swamp. The Savannah sparrows have yet to return to Johnson's pastures, but a loggerhead shrike there was a nice surprise. As was a nice rain shower at 08:15.
The first sandhill cranes might be expected back in about 10 days. So, finally, water is being put out on Pond 1 across from the Visitor Center and on the first pond east of the tracks on the north side of Desmond Road. Water would ordinarily be put out on fields near the boardwalk, too, but repair work to that structure has required delaying that this season.

It didn't occur to me to post this earlier. Jeri Langham, Michele McCormick, Marc Fenner, and perhaps others saw and photographed a Yellow-throated Warbler this morning just downstream of the Gristmill parking area, about here 38.5786780, -121.3426510 Folks coming out later did not find it. I'm looking now.
Take care,
Chris

You mentioned invasion of red-breasted nuthatches this year. Last week my son was returning a boat from Hawaii to San Francisco and while still 100 miles west of the Farallon Islands, two Red-breasted nuthatches decided the boat he was on would make a great resting place. They stayed on the boat for several hours before flying off. Not sure if they made it back to land or not.

Love this bird! I’ve been hearing a RBNU for the past week or so in Auburn
(Placer County) in the canyon near Placer High School.

R-b nuthatches have been reported widely, mostly as singles, in Yolo county just in the past few days. This has the making of an invasion year, the first since 2019, as I recall.
This should be a fun experience for all those who have joined the birding community since then.Listen for those "henk henk henk" calls.

Hello all,
As part of a forthcoming paper documenting an instance of Cliff Swallows nesting on natural cliff faces in a private grassland property in Sacramento County, Zane Pickus and l are seeking records anyone may have of this species nesting on natural substrate on the valley floor. Cliff Swallows often nest on man-made infrastructure such as bridges, buildings, and dams, but instances of the species nesting on natural cliffs are quite rare in this region. Of particular interest are any nesting efforts, successful or otherwise, that occurred in grassland ecosystems. Specific information on the dates and timing of such efforts would also be helpful if available.
Thanks for any help, Julian Johnson Placerville, CA

Greetings all,
Right now there are two Indigo Buntings at the Redding Sewer Treatment ponds and two seen last week (again) at Rancho Breisgau Natural Area off Gover Road in Anderson.
Is anyone else having this event?
We have only a few prior records in the county. BTW the first county record was also at the Sewer Ponds many years ago.
