Wildcat Canyon Sunday

Alan Krakauer
 

Sunday I did an extended hike in Wildcat Canyon Regional park. I started outside the Alvarado Staging area gate on Park Ave since the gate was still closed at 7AM. From there I walked from the north end of the Wildcat Creek trail to Havey Canyon Trail, up Havey Canyon Trial, back north to Mezue Canyon Trail, down that back to Wildcat Creek Trail, and back out. The route also included a quick spur up to the Belgum site. I got back a little after 12.

I managed 62 species which I’m pretty sure is a high count for me in the park. Noteables were:

SAY’S PHOEBE- one early morning seen from Wildcat Creek Trail at the bottom end of Mezue Canyon Trail, not seen when I went by there later in the morning. This seems late, but then I also saw a Say’s yesterday in Oakley on the MDAS East Contra Costa field trip so there must be some hanging around.

WESTERN WOOD PEWEE at Belgum (FOY)

SWAINSON’S THRUSH heard along Wildcat Creek Trail (FOY)

COMMON RAVEN carrying a turkey egg at the top end of Havey Canyon

WESTERN TANAGER and BULLOCK’S ORIOLE  (FOY) in tall eucalyptus trees just north of where Rifle Range comes into Wildcat Creek Trail.

Singing GRASSHOPPER SPARROWS in at least 3 locations- Belgum, the top end of Havey Canyon trail, and the bottom half of Mezue Canyon

LAZULI BUNTINGS everywhere

Most notable miss was coyote. Last time I did a longer trek as far as Mezue and Havey Canyon, I saw over a dozen. A lot of that is probably due to the tall grass now, but still kind of surprising not to see at least one somewhere. Also missed crow, rock pigeon, great-horned owl, cowbird, cliff swallow, red breasted nuthatch, kestral, accipiters.

Anyway, nice morning!

GGAS trip to Sibley Volcano Regional Preserve this morning.

I assume these are migrants. But that there were two present is surprising.

A Merlin (quite well seen) seems exceptionally late.

Western Tanagers FOS

About noon, I was watching a Scrub Jay terrorize a pair of American Robins as it stole their nestlings.  Decided to sit and watch as the robins returned to the nest site several times, wondering how long it takes for them to give up.  But because I was still focused on the tree, I noticed something else.  A male & female Western Tanager lured by the moving water in my yard/fish pond.  Ahh, mother nature is always thought provoking, interesting.

Black-chinned Sparrows -Sibley Volcano RP

rfs_berkeley
 


This morning's GGAS field trip to Sibley had quite a surprise with at least two singing Black-chinned Sparrows. One of these was well seen with scope views. The second only heard.  The first bird gave it's canary-like song for perhaps 10 minutes.

Location:  Round Top Loop Trail looking NW over a steep hillside of Coyote Bush and Poison Oak.  Per Google Earth 270 meters beyond the water tower trail.

I was out there between the Cape Orlando and Gem this morning around 7:30am and didn't see anything. Then the school of bait fish came in and a couple birders showed and I spotted the Brown Booby doing shallow dives near a Western Gull.  She flew around in circles and widen until she almost flew at our heads. This was around 9:00am near when others saw her yesterday morning. Then she flew to the breakwater.

Another sighting was a Peregrine Falcon that flew in and landed on the side of the Cape Orlando.

We found it in the lagoon just south of the MV Cape Orlando and foraging in
the Seaplane Lagoon to the north. Access is along the west side of Ferry
Point Road north of the USS Hornet Museum. Bird roosted briefly on the
stern of the MV Cape Orlando. Distant photos:

Nesting activity in my yard

Johan Langewis
 

I just discovered an Allen’s Hummingbird nest in a redwood tree in my back yard. Other activities include:

Bewick’s Wren nesting in a box on front porch
Nuttall’s Woodpecker nesting in dead pine in back yard
California Towhee nesting in lemon tree in back yard
Chestnut-backed Chickadee in nest box with camera in back yard: 6 eggs laid, 4 hatched on 4/17, one more on 4/18, #6 on 4/19; 4 fledged on 5/8, 2 more on 5/9

Also Brown Creepers were exploring under loose bark on same dead pine for several days, but no nesting. Red-breasted Nuthatches were scuffling with the Nuttall’s Woodpecker over the hole earlier, then were drilling their own holes lower down the tree, but did not nest there. A very productive year. I live in the Oakland hills south of Shepherd Canyon, below Skyline Blvd.

Non East Bay Event, Pt. Bonita Herring Running, Many Birds

Raleigh McLemore
 

My wife just got back from a large herring run at Pt. Bonita (Marin Headlands.)  We observe Harbor Seal births there. Opportunity to see "thousands of birds" from an excellent vantage. About eight of the local Harbor Seals have pups and everything is full of wild excitement.  Her message follows:

"Herring are spawning now in Pt Bonita Cove in the Marin Headlands to the delight of harbor seals and the cormorants, gulls and pelicans. I was there today at low tide around 11 am (near the tunnel to the lighthouse), and could see continual new erupting clouds of sperm in the water in the middle and outside of all the beds of algae or seaweed (don't know my sea plants) below me. Hundreds of cormorants and gulls, dozens of brown pelicans in the water after the fish. Also a dozen or so harbor seals in the water fishing, unusual at low tide; most of the harbor seals resting on the rocks, but today competing for space with hundreds of cormorants and gulls for space. In the distant part of the cove (east of us) we could see easily more than 10,000 Western Grebes out in the cove. Altogether an amazing sight and well worth a trip! Beth

Beth Kean"


Sorry about it not being local East Bay thing, but maybe some might have interest, given the birds.  Of course the run isn't a planned event and we have no idea what it might look like tomorrow.  I rarely post here, hope this is ok.

With firm handshake,
Raleigh


5/9, 9 AM Continuing Brown Booby in Alameda

Patricia Mahoney
 

5/9: No luck yesterday afternoon but this morning brought better luck when I encountered Mark Rauzon at the Alameda shoreline around 9 AM and followed him to the Brown Booby! It was plunge-diving close to shore, south of the ship, Cape Orlando. It moved alongside the Cape Orlando, out west and back around the narrow section of harbor between the Cape Orlando and the Gem State and Adm. Wm. M. Callaghan (docked to the south). I tracked the booby with my scope for some really great views! We watched the bird dive, feed and fly for about 20 minutes before it settled down near the south end of the jetty that’s directly west of the Cape Orlando. Mark headed off and I’m still here watching the booby preen and rest with the Double-crested Cormorants and Western Gulls. It remained in the same spot on the jetty until 10:45 AM- when I heard shrill Gull cries and looked up to see the Booby fly 10’ in front of me! It’s back and diving now by the Cape Orlando.

What a fascinating bird to watch in an interesting area! Yesterday, I enjoyed walking the piers and wandering around for 4 hours, taking in the views and watching other birds and the harbor seals while searching for the Brown Booby. Good luck!

Brown Booby in Alameda

Walt Duncan and I left Walnut Creek around 11:30 today and by 12:20 we were viewing the Brown Booby on the south breakwater of the seaplane lagoon.  fter watching the Booby for a while, I took Walt for a ship tour from the street.  I actually worked on three of the ships docked there.  Contrary to appearances, unlike the USS Hornet, the other five ships are still crewed and working.

Thanks to everyone who discovered and continue reporting this great bird.

I managed to find the Brown Booby roosting about 3/4 of the way out the breakwater next to the Cape Orlando ship. I was viewing it from the USS Hornet side of the Cape Orlando. It was there when I left. Many thanks for the continued reports this morning.

Brown Booby--Continuing late morning, 5/7

Judith Dunham
 

Mary Krentz and I saw the Brown Booby around 10:30 or so this morning. It first appeared flying in from the west in front of where we were stationed at the end of the dock along the USS Hornet. Johan Langewis, also present, first called out the bird. We then moved to the basin between the USS Hornet and the MV Cape Orlando and joined Aaron Maizlish for a second look as the bird made a circuit through the area and then dove. It took off and flew west, toward the breakwater. Mary and I went to the old runways west of Monarch Street, which has a good vantage on the breakwater and basins. After about 20 minutes or so, the bird did not show up again.

Hi all

The brown booby was actively diving in the basin between the cape Orlando ship and the group of naval vessels just outside the seaplane basin this morning from 7:20 to 7:35. Viewed from ferry point road. We lost it when a peregrine went after an osprey.

Walnut Creek bird sightings Monday

rosita94598
 

Rosita and I were out of town over a long 4-day weekend, and it is always nice to be home after the hectic travel of halfway across the country by plane.  But the really exciting thing for me is that we have a Dark-eyed Junco fledgling in our patio this morning.  This bird is feeding by itself, unlike in past years when the adults bring the kids but still feed them.  The adults have been in and out of our patio for quite a while, and it is good to know that they have been successful in their endeavors.

Our house is between the north end of Heather Farm Park and Treat Boulevard. 

In the park this morning, the Caspian Tern was very early, many Violet-green Swallows were flying over the large, mostly natural pond, and a Wilson's Warbler was singing on the east side bushes/willows to the left of the wooden railing.  The two female Mallards have managed to hang on to 18 of their ducklings, a major feat.
