East Bay Birding - Sightings

Re: Crested Auklet RFI

It is now daylight and I hope folks are out there looking for this remarkable bird.  Please post information here immediately if found, preferably with GPS coordinates to help those of who are not sufficiently familiar with Alameda.

Thanks very much,

Melani King’s video - Among 2024 Best of Macaulay Library Videos

East Bay birders: 

I wanted to give a big shout out to local birder, Melani King, for having her video selected by the team at Cornell Lab / eBird / Macaulay Library as one of their 21 favorite videos (worldwide) for 2024! Congratulations Melani! 

The video, which features an Allen’s Hummingbird lovingly building her nest, was the product of a lot of patient observation, and repeated visits (if I recall correctly?) to monitor the bird and nest’s progress. 

I happened to watch the compilation of winning videos today - not expecting to see a video from anyone familiar. What a surprise! The sequence of selected videos is gorgeous, with beautiful music plus bird sounds. 

During these fraught times, watching this was very soothing and peaceful, reminding me why we all enjoy birds. 

Relax with the Cornell Lab's 21 Favorite Bird Videos from 2024:

(Melani’s video appears at 3 minutes, 7 seconds, but I’d highly recommend watching the whole thing).

Huge congratulations and kudos once again to Melani!

Black Skimmers at Stege Marsh

For about a month there have been a group of Black Skimmers showing up on the mudflats along Stege Marsh and Meeker Slough.  When I have been there they were typically out on the mudflats too far from the Bay Trail to get a good photo, but easy to see with scopes.  Late yesterday afternoon they had moved to the east side of the slough next to the old pier and the sun was farther around to the North, so they weren’t  backlit.  Anyway there were 10 or 15 and here is a photo of a couple of them.

Eurasian Wigeon pair + Skimmers

There is a pair of Eurasian Wigeons associating with American Wigeons in the slough east of the bike/walking trail from Pt Isabel to Meeker Slough spotted Sunday March 2. I can't give exact GPS spot, but they were in the small ponds about 3/4 of way from Pt Isabel.
We also spotted a small flock of Skimmers landing on Bay side with some Marbled Godwits on shore of the outlet of stream near the same spot. Unfortunately, once they landed they were invisible due to vegetation.

Robin migration

Dozens of "migrating" robins in evenings and mornings on our lawn and in our fountains and baths.

I hope it's worthy of reporting. Regardless, it's enjoyable to experience it.

  

Continuing Sage Thrasher at Eastshore--Albany Access, Plus

A Sage Thrasher continues (see Zac Denning’s Feb. 9 post) at the McLaren Eastshore State Park, Albany Access. On the north side of the owl enclosure, there is a bench marked “Teal Cove.” Facing north, the Thrasher showed itself in the brambles to the left of that bench for about 4 minutes beginning at 10AM, and then briefly elevated itself so that I could get the photograph linked below. It mostly stays hidden, so some patience is required (or great luck). Please note that there were other very nice birds in the mudflats there today: Cackling Goose, Brant, and Eurasian Wigeon among others.

Northern Pygmy-Owl calling on Mines Road

After guiding a group from San Joaquin Audubon up Del Puerto Canyon this morning I headed solo over into Santa Clara and Alameda Counties. I pulled over below the power lines on Mines Road (37.583289821962175, -121.59561288189542) to change my shoes and heard a NORTHERN PYGMY-OWL calling from the canyon south of the road. Unfortunately it was too far away to locate visually.

Happy birding, and, as always, may the light be with you,

Small Flock of Snow Geese Flying By Stege Marsh

Close to sunset Friday evening a small flock of Snow Geese flew by.  Although I assumed they were Canada Geese I took a few photos and here is a photo. That was a surprise.


A day on my bike birding Eastern Alameda County

This year I decided to try a different angle on birding, seeing how many species I can find the “green” way, which I defined as not using vehicles except public transportation. My efforts so far have been restricted to Alameda and Contra Costa counties, but San Francisco is only a short BART ride away so I’m looking forward to that.  Today was probably my biggest effort of the year, with an outing to eastern Alameda County to track down a bunch of species not likely to be had close to the bay.

I biked down to the Lake Merritt BART station at dawn and took it to the end of the line in Pleasanton.  My first birding stop was Shadow Cliffs where I couldn’t find Wood Ducks, but in the process did see a Barn Owl in a nest box, a nice plus as biking and owling at night are not a safe combo.  My next stop was a quick one, as I found one of the Chipping Sparrows that over-wintered at Tex Spruiell Park in the same spot where I had seen them by car a few weeks ago.  On the way towards Patterson Pass I flushed some Lark Sparrows and had a Merlin perched nicely at the intersection of Patterson Pass Road and South Vasco Road.

I only biked Patterson Pass Road to the intersection with Cross Road, still hoping to get a Loggerhead Shrike but no luck there, but within a quarter mile I had two Cassin’s Kingbirds, one of which flew right at me before landing close by.  On Cross Road I picked up a couple Tricolored Blackbirds and two more Cassin’s Kingbirds. Continuing on towards Cedar Mountain Winery, I had a nice surprise with a Phainopepla popping up on a tree by the road just as I raced by.  That was a relief, as otherwise I would have later biked  quite a ways up Mines Road searching for them. It probably saved me ten miles of biking.    At the winery there were no bluebirds which wasn’t surprising as they appear to be hit and miss, but I did see a Golden Eagle soaring far away

On the way to Mines Road I had both Golden and Bald Eagle, and then on Mines Road what I thought was my last target of the day, Yellow-billed Magpie.  But then I realized that Shadow Cliffs was on the way back to the Pleasanton BART station, so I made a second attempt for Wood Duck and was awarded with a beautiful pair up close. A few minutes later I ran into Isabelle Reddy, who told me she had just seen a Ross’s Goose which I raced down and found it on the beach waiting for a lifeguard to show up so it could take a swim. 

Energized by the nice birds seen, the bike ride back to BART flew by and I was back at the Lake Merritt BART station by 4pm so I decided to bird Lake Merritt on the way home. I did find a Barrow’s Goldeneye and then rode back up the hill home to end the day with 57 miles of riding and 88 species; 8 of those 88 species were new for the “Free-wheeling Derek” eBird account I set up this year, putting me 5 away from hitting the 200 mark.  I created an eBird trip report of the day, with the link below.

Re: Mitchell Canyon bird song BOOMING!

Same at Inspiration Point. At least 3 thrashers singing away. Spring is here!

Mitchell Canyon bird song BOOMING!

Walked up Mitchell Canyon to Deer Flat today; the weather was sunny and eventually got up into the 60s.
The birds were very loud all day, especially in the parking lot, but on up the road as well, with multiple species all singing on top of one another.
About 11:00 it warmed up enough for the thrashers to fire up, and at one point we had at least 4 singing loudly from both sides of the road.
Also, there were several species of butterflies foraging on the road surface out beyond the first bench.
It was absolutely delightful.

Say's Phoebe, Monte Vista HS, Danville

Good evening birders,
 
Don't know if it's all that exciting, but I had my first calling Say's Phoebe of the season this morning. The bird was calling from the top of the press box at the football stadium at Monte Vista High in Danville.
 
Also, the pair of Cackling Geese are still at the adjacent Oak Hill Park--they've been consistently present for several months.
 
Lots of beginning nesting activity going on as well. At least two pairs of Oak Titmice have found cavities in our yard, a Common Raven pair have reclaimed their nest at the stadium, and our Turkey Vultures are already hanging around the nest they've used for the last few years in our backyard. 
 
Seems like spring is springing early!
 
Happy birding!

Sherman Island CBC results

Hi All,

On January 4, 2025 35 birders set out to participate in the 8th annual Sherman Island Christmas Bird Count. While this count is incredibly diverse for an inland count, participation has meant numbers have not been as high as they could be, but this year there was a perfect convergence of a competent crew spread throughout the count circle, a great year for local rarities, and good weather resulting in an astonishing species total of 165 Species for the count, 16 higher than our previous count high of 149.

There were a remarkable 13 new species recorded for the count: Common Loon, Red-throated Loon, American Bittern, Least Bittern, Long-eared Owl, Mountain Plover, Least Flycatcher, Rock Wren, Winter Wren, Mountain Bluebird, Chestnut-collared Longspur, Swamp Sparrow, Purple Finch. Additionally there were second count records of Spotted Sandpiper, American Bittern, Bald Eagle, Short-eared Owl, Hutton's Vireo, Phainopepla, and Brown Creeper, and third count records of White-throated Swift and Oak Titmouse.

We missed several species which have formerly been routine on this count: Wood Duck (reliable areas in the circle at dusk but not checked on the day), Glaucous-winged Gull (bad year for gulls in the circle), Thayer's Gull (same), Rough-legged Hawk (horrible year for them), Western Screech-Owl (no longer regular at traditional Ryer spots though a single bird was found freshly dead on the side of the road in that general region), Burrowing Owl (our worst miss, and several were seen on count week), Yellow-billed Magpie (not at their traditional spot on Ryer this year), Wrentit (resident in small numbers on certain reedy islands but tried for extensively by the boat crew and missed).

There were a total of 26 species seen in only one area, of which 17 were of just a single individual: Blue-winged Teal, Barrow's Goldeneye, Horned Grebe, Osprey, Spotted Sandpiper, Western Gull, Prairie Falcon, Least Flycatcher, Winter Wren, Pacific Wren, Oak Titmouse, Brown Creeper, Hutton's Vireo, White-breasted Nuthatch, Chestnut-collared Longspur, Purple Finch, Swamp Sparrow.

The additional one territory only birds included: Cinnamon Teal, American Avocet, Least Bittern, Golden Eagle, Common Loon, Mountain Plover, Cattle Egret, Long-eared Owl, White-throated Swift. A single bird (Western Screech-Owl) was found dead in one area, and another (Burrowing Owl) was found for count week.

New to the count was the formation of a new area, Area 9, the Sacramento River by boat as covered by Aidan Brubaker and Etan Monk. With this help we were able to get much better counts of waterbirds than ever before on the count.

We set new count high counts of Mute Swan (a disgusting 338. Somebody needs to start culling these things), Lesser Scaup (1908, thanks entirely to area 9), Hooded Merganser (65, prev high 28), Ruddy Duck (about 2500, prev high 1400), Bufflehead (1355, prev high 669), Ring-necked Pheasant (128, prev high 19. Thanks almost entirely to coverage of Webb Tract (recent release maybe?)), Wild Turkey (80, prev high 28. Thanks almost entirely to two groups on Bethel Island and Rio Vista), Pied-billed Grebe (258, pre high 119. Mostly due to area 9), Turkey Vulture (245, prev high 188), Swainson's Hawk (23, prev high 7), Red-tailed Hawk (297, prev high 232), White-faced Ibis (139), Virginia Rail (39, prev high 15), Sora (44, prev high 16), Sandhill Crane (2768, prev high 1517), Rock Pigeon (2988, prev high 1852), Anna's Hummingbird (170, prev high 141), American Kestrel (150, prev high 117), Common Raven (106, prev high 84), Horned Lark (1333, prev high 47), Tree Swallow (241, prev high 134), Barn Swallow (12, prev high 1), House Wren (70), Common Yellowthroat (193, prev high 76), White-crowned Sparrow (2366, prev high 1975), White-throated Sparrow (5, prev high 3), Song Sparrow (394, prev high 186), Spotted Towhee (132, prev high 114), Western Meadowlark (1929, prev high 1100), Brewer's Blackbird (16869, prev 14,351), Brown-headed Cowbird (2765, prev 289), House Finch (2765, prev high 1733),

Minor high counts included: American Wigeon (385, new high count by 1), Common Goldeneye (746, new high count by 7), California Quail (44, high count by 2), Great Egret (294, prev high 274), Cattle Egret (tied prev high, all in one area), Mew Gull (54, prev high 47. Almost all at Piper Slough), Barn Owl (9, tied prev high), Great Horned Owl (40, tied prev high), Short-eared Owl (3, prev high 2), Orange-crowned Warbler (103, prev high 98), California Towhee (43, tied high count)

Low counts included Tundra Swan (47), Northern Shoveler (189), American White Pelican (19), Ferruginous Hawk (3, tied low), California Gull (44), American Robin (93, prev low 279), Cedar Waxwing (4, prev low 27), Red-winged Blackbird (25,608, prev 31,576).

In general, shorebird and dabbling duck numbers were pretty low considering effort, reflecting lack of standing water in many areas of the region. Collared-Doves continue to show their downward trajectory in the region, with only 200 this year, compared to a high of 834 in 2019-20 and a low of 173 in 2021-22.

Best,

Logan

Re: Pacific Wren

Excuse me, clearly Big Springs Drive is a road that does not exist. That would be South Park Drive.
