Mitchel Canyon sightings

Philip Georgakakos
 

Hi Folks,

Today Teale Fristoe and I checked out Mitchell Canyon this morning from around 5 to about 11. If you plan to check out this area pre-dawn you need to plan around the gate at the visitors center being closed. We parked about a mile away and biked in. From the visitors center we walked down Mitchel canyon road pre-dawn to the second access point to Red Road. Then we poked around Red Road, Black Point Trail, and some of the dead end trails that lead to the park boundary, slowly we headed back to the visitors center. There were loads of warblers in mixed flocks with vireos and flycatchers.

Notable sightings:
- Western Screech-Owl tooting off Mitchell Canyon Road
- Common Poorwill calling and flying off Red Road
- Calliope hummingbirds(3) off Red Road and Mitchell Canyon Road
- Cassin’s Vireos(2)
- Hammond’s flycatcher(10) Scattered throughout, the most either of us had seen in an outing
- Nashville Warbler(6)
- Hermit Warbler (5)
- a single Macgillivray’s Warbler Male off Black Point Trail.

8 warbler species and 56 total species on the day. The flower diversity and abundance is also pretty amazing out there right now. Find the complete checklist here https://ebird.org/view/checklist/S55057989.

Hope everyone is enjoying the spring!

Calliope on Garin Ave, Hayward, April 17

Dave Weber
 

Saw Mark Rauzon's ebird report yesterday so I was at the bank of Pride of
Madeira along the upper part of Garin Ave early this morning. I parked at
the Garin RP parking lot (no fee!) and walked back. I walked up a steep gap
near a phone pole to a narrow cement culvert. Looking down I saw a male
Calliope Hummer 20 feet away sitting still for two minutes around 8:10. Then
I saw Jim Lomax across the road but we never refound the Calliope. One or
two Rufous were around but no Black-chinned. The Calliope is 300 in the
county for me. Later Jim and I went to Ardenwood Farms and joined Jerry Ting
to not refind the Gray Flycatcher.

Though I have not seen it for over a week, one of our local Heather Farm birders Rosalie, saw the Tropical Kingbird yesterday about 11 AM.  It was on the fence around the new Community Garden area. 

Late this afternoon I took a short bike ride for exercise, during which I saw a Bobcat below Lime Ridge east of Citrus.  When I returned home, I thought I should check Heather Farm for the Kingbird, but had no luck.  I did have quite a few Golden-crowned Sparrows following me, though.

I found a Gray Flycatcher at Ardenwood this afternoon.  Plain drab Flycatcher with longer bill and tail than Hammond's.  No distinct eyering.  Was also dipping its tail like a Phoebe.  Near that trainyard.  Dropped pinNear Ardenwood Historic Farm, 34600 Ardenwood Blvd, Fremont, CA 94555https://maps.app.goo.gl/7X3Au I hope sharing the Google maps location works.https://flic.kr/p/2ftSrwA

Re: UC Berkeley Peregrine Falcons - eggs warm enough?

Fred Werner
 

Is there a betting pool as to when folks think the Campanile Peregrines'
first egg will hatch? I'll place my bet on this Thursday, April 18,
4:50pm...

Thank you Anne! The second egg appeared sometime this morning, I think
just before 8 am!
The cam lets you go back up to 4 hours, and you can see the eggs at
8:00, 9:41, and 10:48, and 11:18.
It looks like dad came in soon after the egg was laid, and relieved mom
for an hour to go feed.
Since then, it’s been mom sitting…

With a 29-33 incubation period, that means hatching sometime starting
the week of April 15th..

April 14, 2019: Black Scoters Continue at Richmond Marina

Patricia Mahoney
 

Sunday, April 14, 5 PM: Two adult male Black Scoters continued in the corner of the Richmond Marina, close to the pedestrian path. They’re looking good and staying together: much snoozing, some preening, stretching and swimming... excellent binocular views. No vocalizations during my 20-minute visit (last stop on a great spring birding day!). The Black Scoters kept company with Surf Scoters, Western Grebes, a Clark’s Grebe, Horned Grebes and Coots. A male Surf Scoter dove and resurfaced with a whole mussel which it manipulated and then swallowed easily. Two Black Oystercatchers foraged along the edge of the rocks below the path.

I parked at Shimada Friendship Park and walked a block to the harbor corner; I spotted the Black Scoters from a half-block away:

Mitchell Canyon Nashville Warblers, etc.

Derek
 

Following up on a couple other interesting posts this week on Mitchell
Canyon, I decided to make that my destination this morning and it
didn't disappoint. I set personal highs for both Nashville Warbler
(4) and Black-throated Gray Warbler (16). Other highlights were
Hammond's Flycatchers, Hermit Warblers, and a single Calliope
Hummingbird. The 6 mile hike focused mainly on Black Point Trail that
I took all the way around the mountain though it was too early for
Sage Sparrows on the west side. A one-mile stretch of that trail was
very productive early morning with warblers galore with many good
horizontal views.

This is the earliest in the migration I've ever birded Mitchell Canyon
and despite it being too early for some key species, I found the
activity level very high. And of course the wildflowers are added
bonus.

Northern Pygmy-Owl at Sunol Regional Park

Donald Lewis
 

Thursday, our small group had a glorious morning at Sunol regional park,
starting at the last parking area at 8am. We heard a NORTHERN PYGMY-OWL not
far past the bridge on the Ohlone Camp trail (the main road). Other
highlights of the 48 species seen were 2 WESTERN KINGBIRDS and 2 BULLOCK'S
ORIOLES on the way back near the cattle pond on the McCorkle trail. But
besides the birds, the wildflowers are spectacular, especially along the
Canyon View trail as we made a loop return from Little Yosemite to the
parking lot.

Royal Tern Alameda

John Luther
 

Hi All,
While doing a bird survey at the Alameda Reserve, Alameda Point, Alameda I observed a single Royal Tern.  It was calling while flying over and by me at about 9:30 AM today April 11.  This area has no public access, but the bird could go north, south or west over or along the bay.  It was flying NW towards SF when last seen.  It had very white underwings with no large black area as seen on Caspian Terns also in the area.  The bill was orange red not the deep red of the Caspian Terns and the bill was thinner (but not as thin and long as an Elegant Tern) than the Caspian Terns.  The overall bird seemed less bulky "slimmer" than a Caspian.
Also seen in the area by the breakwater was a single Brant and 8 Brown Pelicans.  There are now over 200 Caspian Terns at their colony in the SF county portion of the Alameda Reserve. I looked for the Royal Tern in the colony area, but did not find it there.

Globe lilies have been out for 2 weeks, on their trail, but also on the main fire road.

Thank you for the bird info!

Subject: [EBB-Sightings] Mitchell Canyon Calliope Hummingbirds 4/10

Yesterday Phil Georgakakos and I had a great day exploring Mitchell Canyon on the northern side of Mt Diablo. We started by walking down the Mitchell Canyon Fire Road until it started heading uphill, then we backtracked to White Canyon, taking Red Road then Black Point Trail for maybe a quarter of a mile. On the way back to the parking lot we took Globe Lily Trail.

It was too early for globe lilies and many migrants, including most warblers, flycatchers, and bunting type birds. However we saw many Hammond's Flycatchers throughout the canyon and heard two Black-headed Grosbeaks. The highlight of the trip for me were a whopping 8 Calliope Hummingbirds, almost all males that were displaying and posing on exposed branches. We saw these birds in several locations along Red Road, Black Point Trail, and Globe Lily Trail.

We were unfortunately too late in the morning to hear Common Poorwills, but we did find the headless corpse of one on Red Road. Does anyone know what kind of predator would kill a bird like that and only take its head?

Brushy Peak - Meadowlarks and others

Mike Shannon
 

Took a hike today up the west side loop at Brushy Peak and spotted numerous Meadowlarks sitting on the fence posts. Watched a beautiful red tailed hawk hunting at the top of this trail. Also, many red winged blackbirds, a few Scrub Jays and at least one song sparrow. There was a Northern Harrier up there as well and we saw him again (or his twin) down at the bottom.The highlight was a Burrowing Owl sitting at his burrow, watching us watch him.Mike ShannonCastro ValleySent from my Verizon, Samsung Galaxy smartphone

Tilden Nature Area, Jewel Lake

Mike Shannon
 

I took a nice though brief hike from Indian Head to Jewel Lake. There was a small group of bushtit in the low bushes to the left of the trailhead (up a few steps). I heard Pacific Slope Flycatcher throughout the park and got a glimpse of one down near the lake. I hiked the secondary trail that more or less follows the creek on the side opposite of the main path. I saw the Black Headed Grosbeak high up in the tallest trees. There were Wilson's Warblers where the trail comes along the backside of the lake. Standing there for awhile I saw Song Sparriw ( not shy). There was a vireo, I think it was Huttons but short of a DNA test, I hesitate to positively identify him. The face marks were wrong for warbling vireo which leans me toward Huttons. An Oak Titmouse showed itself. There was another warbler, larger than the easily recognized Wilsons. I think it was a Yellow Warbler. A Stellars Jay was hanging around as were a couple of Mallard. I heard hummingbirds a few times but didn't take time to find them. Crows and Scrub Jay were here and there. Juncos were hanging around the footbridge along with more Bushtit.

I went around to the other side of the lake and listened to that damn Virginia Rail sounding off right in front of me and I could NOT see him. I am quite sure he was mocking me and a few others who gathered around to try and find it.

In the trees above was a Downy Woodpecker, the white streak down the back was evident.

All in all a fine morning of birding.

Hooded Orioles

FOS Hooded Orioles have arrived in my yard, finally. This year and this morning, a male and female together have discovered my hummingbird feeders. In the past, the male arrives in March then the females and family members show up. Love this migration stuff.

Nice, Pam! I was fortunate enough a few months ago to spot Virginia Rail on Wildcat Creek along the Gorge Trail! I captured a movie, too, on my Youtube channel (gambolinman).

The VIRGINIA RAIL's repeated and distinctive call was at Jewel Lake, Tilden Nature Area on the morning of Apr 7 and last week.
Vocalization was similar to this: https://ebird.org/media/catalog?taxonCode=virrai&mediaType=a®ion=California,%20United%20States%20(US)&regionCode=US-CA&q=Virginia%20Rail

Selasphorus Hummingbird

Elizabeth Leite
 

Yesterday, April 6th, mid-morning I had a fleeting view of a male Selasphorus Hummingbird at one of my feeders.  I checked eBird for other central Contra Costa  recent sightings and found several. Over the years  I've only seen one or two females or immatures in our yard so this was definitely a pleasure.
