Junco Fledgling Visits Our Patio

rosita94598
 

Our friend, Bob, was visiting our Walnut Creek house after the two of us took a between shower walk around Heather Farm Park. As we sat talking, I noticed a streak pass the window. Thinking a Lesser Goldfinch must have then hit our sliding glass door, I looked around the corner. Instead of a goldfinch, it was a fledgling Oregon Junco, which was following an adult into the patio. I showed it to Bob and grabbed the meal worm container from the refrigerator. Hoping they wouldn't spook, I slid open the door and tossed a big spoonful of worms onto the cement.

About the same time the juncos arrived, so did a CA Towhee, but I put enough worms out that the fledgling junco was fed 8-10 worms before the towhee scarfed up the rest.

This was definitely cool.

Little Drummer Boy

Jaan Lepson <lepson@...>
 

Hi All,

For the past 5 days a Nuttall's Woodpecker has been drumming in my
neighborhood. He regularly visits at least 4 trees, based on distance and
direction of the drumming. I've enjoyed its staccato rapping - not sure
if I've heard any drumming from home before. It also lets loose with a
loud, strident "klee-klee-klee-klee!" vocalization that I've not heard
before (and don't see mentioned in Sibley).

cheers,
Jaan

The Heartbreak of Predation

Jaan Lepson <lepson@...>
 

Hello all,

Once again Mourning Doves have nested in my yard. This time they chose to
build in a hanging basket of epiphyllum cactus under the eaves in front of
my office. Good choice - nice and dry and not too obvious. Meanwhile, a
pair of crows are nesting in the top of the neighbor's redwood - you can
see where this is going.

The dove chick hatched and all was going well until a couple of days ago,
when I noticed a crow spending too much time nearby in the front yard.
Sure enough, after a couple of days we saw that the dove was gone and the
basket was still swinging. I went out to check, and a crow flew off from
the adjacent juniper tree. We must have just missed the predation event.

As I've said before, it's a wonder we have any doves at all!

good birding,
Jaan

CA Towhee bigger and stronger than Juncos

rosita94598
 

Starting yesterday morning, I noticed the CA Towhee, which was joined by a second one, has been taking the meal worms from our patio. If the Oregon Junco arrives first, it can grab a beakful of worms, otherwise the CA Towhee is much to big for the Junco to compete. The Junco lands nearby, but does not move in to grab worms. The Towhee(s) will grab them all. The Chestnut-backed Chickadees have not figured out that we put some worms for them into a little basket near the peanut feeder.

Meanwhile, a female Anna's Hummingbird and female Lesser Goldfinch continue to take nesting material. Sometimes it is the commercial material, sometimes raw wool.

Hayward Shoreline Yellow-b. Chat

bdisme51 <bdisme51@...>
 

Went to the Hayward Shoreline at the west end of Winton Avenue this morning right as the rain ended and the sun came out. I had a singing Yellow-breasted Chat in the trees across from the park office.

I also walked out to the City of Hayward ponds. The Red-necked Phalarope count was up to about 40 birds and I refound 2 of the 4 Black Skimmers reported by Bob Richmond yesterday.

The trees around the parking lot still had Orange-crowned, Yellow-rumped and Wilson's Warblers, Cedar Waxwings, Hermit Thrush and a Pacific-sloped Flycatcher. Did not refind the Nashville Warbler or Cassin's Vireos reported yesterday.

Re: Patterson Pass and Mines Rd (Dusky Flycatcher and Blue Grosbeak)

Eric Pilotte
 

As supporting evidence of the Dusky Flycatcher Zach and I saw on Sunday at Patterson Pass, I've uploaded a photo to the Yahoo Group 'Photos' folder for others to see (it is pending moderator approval at the moment). We spent 30-45 minutes studying the bird, and although the photo is imperfect to say the least, it is helpful as it shows the eye-ring. We also heard the bird giving a 'whit' call multiple times. Anyhow, feel free to email Zach and me with any comments/questions/thoughts on the picture/bird.

Nest box update

Johan Langewis
 

To review: Chestnut-backed Chickadees laid 7 eggs 3/28 and 3/29. 4 hatched 4/13 Photos posted previously. Since then (Measurements taken from TV image, ratio calculated to get true length):

4/13 At hatching chicks ~ .75" long

4/15 1.1"

4/16 1.5"

4/17 1.7" Fuzzy tufts appear on head. Dark lines on back and wings appear, probably feather tracts. A row of dots appears on wings.

4/18 1.9" Row of dots on wings is now a row of ridges.

4/19 2.1" Dark areas expanding, feathers developing on wings.

4/20 Chicks are getting too big and fat to measure. More fuzz on bodies, feathers on wings longer.

8 warbler day at Mitchell Canyon

Ted Robertson
 

Took a furlough day today and birded Mitchell Canyon on the north
side of Mt. Diablo. It was an 8 warbler species day; 4 Wilson's, 10
Orange-crowned, 5 Black-throated Gray, 2 Yellow-rumped (Audubon's), 9
Nashville, 4 Townsend's, 1 MacGillivray's, 1 Hermit. Most of the
warblers were spotted feeding in the coast live oaks (Q. agrifolia)--
it seemed that every other grove of oaks had warblers in them. Also
saw a pair of male Lazuli Buntings, and Warbling and Hutton's
Vireos. Flycatchers included several Ash-throated and Pacific-slope
and 1 Hammond's.
Flowers were great too, the highlight being the Broomrape
parasitizing the chamise, (Orobanche bulbosa) along the Red Road Trail.

Winton Ave - possible Plumbeous Vireo

Lori Arthur <loriarthur61@...>
 

Hi. This morning, I did an exclusively songbird-birding trip to the Winton Avenue entrance at Hayward Shoreline. It was excellent birding, with numerous small songbirds in the trees and bushes around the parking lot and down the trail:
Pacific-slope Flycatcher
Black Phoebe
Cassin's Vireo
Horned Lark (seen during an unsuccessful try for the Lapland Longspur at the dump)
Barn Swallow
Cedar Waxwing
Hermit Thrush (heard only)
Bushtit
Yellow-rumped Warbler (both subspecies)
Orange-crowned Warbler
White-crowned Sparrow
Song Sparrow
Lincoln's Sparrow
Savannah Sparrow
Brown-headed Cowbird
Red-winged Blackbird (including a male with golden-orange-yellow lesser coverts)

 The most interesting bird was another Solitary-group vireo, similar in shape to the Cassin's (perhaps slightly bigger and less warbler-like), but much grayer. It was all in grayscale, with almost no hint of creamy/buffy in the flanks and plain white belly. It gave me prolonged views in an opening of the myoporum thicket. My first impression was that it looked like a Gray Flycatcher, but the "glasses" and bill shape ruled out Empidonax flycatchers. The auriculars contrasted sharply with the throat. The best conclusion, based on plumage, seems to be Plumbeous Vireo, but I know Cassin's can be very gray this time of year. Opinions are welcome.

MDAS trip to North Briones Regional Park

rosita94598
 

It was cool and breezy this morning, but 8 birders still counted 52 species at North Briones. After coming out of the trees to the grassland, we found a female Mallard with 2 ducklings at the first of the Maricich Ponds. As we climbed the Crest Trail, we found Lark Sparrows, Horned Larks and American Pipits. Then, along the ridge we had a Golden Eagle being harassed by three crows and a Red-tailed Hawk. The hawk was about 1/3 the size of the eagle, but dove at it repeatedly. At the first of the Sindicich Lagoons, we had two male and one female Gadwall. The second, and larger pond had a pair of Buffleheads and a Double-crested Cormorant. Behind the pond was a distant Lazuli Bunting. Western Bluebirds seemed to be everywhere. A pair of White-tailed Kites were acting in a romantic way and a pair of Red-tailed Hawks were seen copulating. As we returned to the parking area we had Blue-Gray Gnatcatchers, an Ash-throated Flycatcher and a nice singing Orange-crowned Warbler.

Patterson Pass migrants

richard s. cimino
 

Jim Ross and I made our way to Patterson Pass today about 3 PM.
We missed birders Zach Baer and Eric Pilotte, they reported a Blue Grosbeak.
Their sighting supports the mid April Blue Grosbeak typical arrival date.
We did met Steve Huckabone and his wife around RM 6.04, so we had to stop birding long enough to chat.
That only lasted twenty seconds, because the large cottonwood trees in that area were so full of migrants.
RM 5.47 scan the hill side on the south side of the road. There are now two pairs of Burrowing Owls a few hundred feet apart.
RM 5.90 to RM 6.21
1 Willow Flycatcher in an area of the large cottonwoods, very low directly above the creek. This Flycatcher lacked an eye ring.
1 Ash-throated Flycatcher
1 Western Kingbird
2 Black-headed Grosbeaks
2 Bullocks Oriole
1 House Wren
5 Nashville Warblers
3 Wilson Warbler
6 Black-throated Gray Warblers - one female
5 Audubon Warblers - all males
1 Selasphorus Hummingbird - moving very fast
1 Shrike
2 Hermit Thrush's
3 Ruby-crowned Kinglets
4 White-crowned Sparrows
5 Golden-crowned Sparrows
2 Chipping Sparrows
Lark Sparrows - several

Nesting Juncos in Walnut Creek

rosita94598
 

Our Chestnut-backed Chickadees have not yet learned that we are putting out meal worms in the morning. This morning I noticed a California Towhee in our patio early, so I quickly tossed a little seed and then some meal worms. The Towhees were collecting them like crazy last summer when feeding babies, but this one practically walked on them and didn't seem to pay attention.

while the Towhee was still present, an Oregon Junco came in and picked up 3-4 worms and flew off. It did this twice more before I left for church. It must have a nest somewhere nearby, possibly in the redwood trees which are along Treat Boulevard a couple of houses away.

We are still having some White-crowned Sparrows come, they like the meal worms, too. I did not see any Zonatrichia sparrows in Heather Farm Park Thursday or today.
