Mitchell Canyon Stuff

I was at Mitchell Canyon on Saturday birding, biking and hiking..


My birding highlight was a singing Bell's Sage Sparrow near the summit of the Black Point Trail. This trail was hummingbird alley as there were about 8 Rufous hummingbirds the first 1/4 mile  from the White Rock trail intersection. There was a great stand of California larkspur blooming here - a spectacular white larkspur that grows over 4 ft. tall.


I also heard the canyon wren at the previously reported location.- thanks Jeff!


Lots of Townsends warblers and the only empidox flycatchers were Pac-slope - maybe 6.


Biking down from Deer Flat along the canyon trail, I biked through an amazing "mayfly" hatch at around 1,000 to 750 feet elevation - I thought I was next to a trout stream (I have a picture of a mayfly if anyone is interested in identifying mayflies -- email me). Mitchell Creek is running about 4 feet wide up here. I wonder how many salmon will try to spawn in the creek this year after years of drought. In 1985, salmon were found up to 920 ft. elevation in the creek!


Mitchell Canyon is always interesting....

ebird pass-alongs -- Red-necked Grebe and Long-tailed Duck

Bob Power <rcpower@...>
 

Hey all,

Just passing some eBird reports along.  Dan Roth has a nice photo of a breeding plumage Red-necked Grebe at ShadowCliffs on Saturday. No idea if that bird is still being seen.

Bob Richmond had a Long-tailed Duck on the shore, not on the water on Sunday. Not a breeding-plumage bird.

Rufous HB, Wisons Warbler

judisierra
 

A possible Rufous Hummingbird male spent this morning in my yard enjoying a flowering shrub. The resident Anna's wasn't around. This is only the second ever selaphorous HB I've seen in my yard. A Wilson's Warbler was also present.
Yesterday a large flock of Cedar Waxwings (about 50) was attempting to alight on a not so sturdy neighbor's shrub. Yesterday in Strawberry Canyon Berkeley, I saw for a second time just as I was thinking about it, the necklaced partially leucistic Robin and heard a faint FOS Olive-sided flycatcher. So faint, I wonder if it had been around earlier this week but not loud enough through the rain to have been "found". This morning it was a bit louder.

Just to note I say posssible Rufous because it it had barely visible green flecks along the back, in a linear fashion

Mines road Saturday

rosita94598
 

Mt. Diablo Audubon Society visited Mines Road Saturday with good success.  We had two big misses, including Lawrence's Goldfinches and Phainopeplas.  But we had about 75 species total, though many of the species were of just one or two birds.  Our only Bullock's Oriole and Western Tanager sightings were at mp 2.72, where we also found a Kestrel and a sizable flock of Cedar Waxwings.  Both Cliff Swallows and White-throated Swifts were under the road bridge at the south end of Del Valle Reservoir.  A Spotted Sandpiper and a Great Blue Heron nest were seen from the gravel beach at the south picnic/swimming area.  A Bald Eagle flew over the picnic area parking lot.  A California Thrasher was on the hillside around the bend and above mp 5.75, along with the great stand of Delphinium californicum, a tall whitish larkspur.  One person saw a Lazuli Bunting here, too.  A Greater Roadrunner was seen going around the bend farther up the hill and many of us walked higher looking for it, to no avail.  This is very close to the mp 6.0 area where this species has been recently reported.  A Sharp-shinned Hawk flew over our lunch site at the cattle corral located at mp 17.6. 

The Junction was jumping with lots of cycles, both bi and motor, but the hoped for Larries were not in appearance.  We also spent a large amount of time and walked a great distance along San Antonio Road south of the Junction looking for Lewis' Woodpeckers, of which we finally found a courting? couple.  A Tricolored Blackbird, Yellow-billed Magpie and Western Kingbird were at the pond another mile or so farther south.

As we returned home, near the new CDF fire station we heard a Bell's Sparrow and one person actually saw the presumed singer before it dropped out of sight.  We also stopped again just above mp 5.75, where the CA Thrasher was again seed/heard and we found a couple of Rufous-crowned Sparrows.  We had three Golden Eagles over us during the morning stop and one was again seen in the late afternoon.  A female Selasphorus hummingbird was in the monkey flowers below the roadway.

Say's Phoebes fledge young, San Ramon

SteveLombardi
 

A pair of Say's Phoebes nesting on a home in San Ramon fledged their young today. We saw the parents feeding four active kids on a fence near the nest this morning. This is the first brood of any species we've noticed this year. They appear to be enjoying the spring weather, and we hope you are, as well.

Immature bald eagle over Tilden

Richard Sintchak <rich815@...>
 

While picnicking with with family around 2pm this afternoon at the Tilden botanical gardens a beautiful immature bald eagle flew over promptly heading northwest.

As for the earlier discussion about bald eagles in this area I want to share an earlier sighting about 4-5 years ago of a full-adult plumage bald eagle flying over while I waited on line at Acme Bread at Cedar St and San Pablo Ave. It was quite low, in perfect plumage and the lighting was terrific. It was being chased by two crows so a bit of a ruckus was evident. As it flew off three or four others on line who obviously saw it had the most confused looks on their faces. I said aloud to all, yes, that was a bald eagle. And they all broke their frozen face confusion into broad smiles and exclamations of astonishment most having never seen one in the wild let alone flying over West Berkeley at 10am one Saturday morning!

Re: Rufous Hummingbird - Antioch yard - 4/21

What a coincidence - yesterday there was a male Rufous Hummingbird at my feeder in the Oakland Hills.  They must be migrating through.

Amateur Hour

I am not a true birder, just a nature observer, or an amateur nature generalist.  Our house, in Lafayette sits below a bird pathway.  Most morning we hear and see, if we are outside, a flock of Canada Geese flying overhead toward the East, North East towards Walnut Creek.  About dusk they fly back to the Lafayette Reservoir.  Blackbirds, hummingbirds, robins, and if we are very lucky, Varied Thrust in the yard just behind our retaining wall in the back of the house. 

Raptors seem to be North of Highway 24, as we see only a few, far in the distance. One of the true beauties of Central Costa County is the birds.

Black Diamond Mines R. P. - 4/20

Paul Schorr
 

Yesterday, 4/20, Mt. Diablo Audubon Society conducted its annual outing to BDMRP.

Highlights included:

Canyon Wren - beautifully seen and heard along the Chaparral Loop Trail above the Hazel Atlas Portal
Blue-gray Gnatcatcher - along the Chaparral Loop Trail, a pair was seen and one of the birds was on the nest
California Thrasher - seen and heard along the Ridge Trail
Ash-throated Flycatcher - heard in many locations, but seen beautifully in the upper parking lot
Bullock's Oriole - nicely seen in the upper parking lot
Phainopepla and Cedar Waxwings - seen in the trees in the main visitor center parking lot
Orange-crowned and Wilson’s Warblers - heard in many locations
White-throated Swifts - many seen and heard along the Chaparral Loop Trail
Violet-green Swallow - a perched pair was seen nicely in the upper parking lot
Western Kingbird - seen along the Ridge Trail and the entry road near the Old Moeller Ranch
Belted Kingfishers - a pair was seen frequenting an exposed bank in the gully on the west side of the entry gate

In addition to the fifty species seen/heard, the group enjoyed numerous spring wildflowers and the vistas were spectacular. Great time of the year!

Good birding,

Mitchell Canyon

In addition to hoped-for seasonal goodies (Lazuli bunting, western tanager, black-headed grosbeak, migrant warblers, flycatchers), I had two unexpected finds, birds that I associate with Black Diamond Mines rather than Mt Diablo: Phainopepla and Canyon Wren.

Phainopepla location:
Near the beginning of the trail, on the west side.  There is a derelict, farm-like work area behind the park residence visible from the Mitchell Canyon trail.  It is distinguished by three, blue, plastic (water storage?) tanks.  Phainopepla was in the oaks there.

Canyon Wren location
Roughly 3 miles up the trail.  After the Mitchell Canyon trail begins its ascent to Deer Flat and clears out of riparian habitat, the view of the opposite side of the canyon (to the east) opens up.  Canyon wren was singing from the sheer cliff face there. 

Apologies in advance to others if these birds have already been reported.

Good birding, 

Jeff Acuff

Sunol, 4/20, late Ferruginous Hawk, great hummers!

Robert Furrow
 

Today I birded Sunol Regional Wilderness from 9am until around 12:30pm.  As I first crossed the creek onto Camp Ohlone Road, I noted a soaring light-morph adult FERRUGINOUS HAWK.  This large, pale bird showed large white patches in the primaries (seen from above) and a gleaming white base to a reddish-tipped tail.  It circled with a few vultures quite high up, before heading north.  It's getting very late for a Ferruginous Hawk.

My main plan was to walk up the Cerro Este Road from Little Yosemite, to check on the large patch of mimulus flowers for hummingbirds.  I was rewarded!  Several adult RUFOUS HUMMINGBIRDS were chasing other hummingbirds, and one male gave repeated flight displays.  Soon after I noted a nice male CALLIOPE HUMMINGBIRD with its lovely streaked gorget and short tail.  Later on I encountered a female as well.  I also found a single female BLACK-CHINNED HUMMINGBIRD.  She stood out with her more "necked" appearance, gray crown, long slightly decurved bill, faint peachy flanks, and tail that was a bit longer than her folded wings.

I then proceeded to hike up to the Cerro Este overlook, where I noted 3 HORNED LARKS, 3 LARK SPARROWS, 1 GRASSHOPPER SPARROW, and 1 SAVANNAH SPARROW.  ROCK WRENS were abundant, and several SHARP-SHINNED HAWKS circled overhead.  Over the course of the morning I saw what seemed to be at least 3 individual GOLDEN EAGLES.


Happy birding,
Rob Furrow

Mitchell Canyon Tuesday

rosita94598
 

The roads were somewhat muddy following the rain, but the birds were pretty good today.  I started in just after 9 AM.  No Phainopepla ner the residence area for me, but the male was there when I came back out.  I saw 5 western warblers, Tracy Farrington may have added a couple more.  Mine were Audubon's, Black-throated Gray, Wilson's, Hermit, and Nashville.  Tracy had a Townsend's and I think an Orange-crowned. 

At least 3 Black-headed Grosbeaks were there and several Ash-throated Flycatchers.  Bewick's Wrens seemed to be everywhere.  A Western Tanager was in the oaks above the first trail intersection, as was a singing Hutton's Vireo.  Also seen out there were several Warbling vireos.  I did not fare so well with the empids, but did have one certain Pac-slope. 

I did walk the globe Lily Trail, which was particularly muddy and for me, un-birdy.  I did see a couple of nice yellow Broomrapes, some Purple Sanicle and Blue/purple Larkspurs, along with the other expected Mitchell Canyon flowers.
