Arrowhead Marsh, December 5, 2009

December 5, 2009
Wild Birds Unlimited Bird Walk
Arrowhead Marsh, Oakland
Leader: Chuck Groff

It was overcast and cool, in the low 50s and the day started
with a chilly breeze. But the sun came out a bit later and it
warmed up nicely so the Turkey Vultures eventually found
thermals and took to the wing.

There were a few large rafts of birds in the water, and
several areas on shore with sizeable flocks of birds standing
and resting. And we saw a nice variety of species, including
the California Clapper Rail.

Brown Pelicans performed amazing dives nearby to the
great appreciation of the group.

November 7, 2009
WBU Bird Walk
Lafayette Reservoir
Leader: Chuck Groff

The weather was sunny and mild. We were a small group of
six people, complete with beginners and experts, and
everyone enjoyed the walk. The usual large flocks of
cormorants, doves, and ducks were not present and the
total number of birds was only a fraction of what we've
seen in previous years. Even though we didn't see usually
common birds such as Robins, Juncos, Killdeer and
Mallards, we still saw a good number of species. So the
variety was good even if the numbers were not.

One highlight was a Cooper's Hawk who took exception to
a Red-tailed Hawk flying through it's territory. It dove and
harrassed the Red-tail not far above our heads and both
birds added their cries and screeches to the action.

New for this location for our bird walks were the Hairy
Woodpecker, Hermit Thrush, Cackling Goose, and the
Lesser Goldfinch.

By request, I'll order my lists from now on using the
complete common names.

October 3, 2009
WBU Birdwalk
McNabney Marsh and Mt. View Sanitation Ponds
Leader: Chuck Groff

The weather started out cool and breezy, but warmed up
quickly and was nice and comfortable the rest of the walk.

Like last year, the large flocks of waterfowl we saw in
earlier years were absent and those we did see were in small
groups scattered here and there. Also like last year, we were
treated to a Red-shouldered Hawk who perched 10-15 feet
above the trail in front of us for quite a while. As we
approached, he moved until we passed, then returned to his
perch.

We also had good views of a Green Heron hunting along
the water line, a Black-crowned Night-Heron that we
surprised into a short flight, and a single American Pelican
that came in and landed in the reeds.

Pine Canyon, June 6, 2009

June 6, 2009
Wild Birds Unlimited Bird Walk
Pine Canyon, Mt. Diablo, Walnut Creek, CA.
Leader: Chuck Groff

We had a beautiful day for birding, cool in the morning,
and not too hot later, just in the mid-seventies, with breezes
and clear, sunny skies.

An abundance of birds just beyond the trailhead held our
attention and stopped our forward progress for quite a
while. Small groups of Western Kingbirds squawked and
scooted through the trees. At one point five of them
crowded into one small area on a single branch and sat for
awhile.

A group of Bullock's Orioles chased each other around in
what seemed to be a territorial battle. Across the field a
Red-tailed Hawk perched near it's nest, where a large chick
milled about and flapped its wings.

A Peregrine Falcon sat atop Castle Rock in the distance,
and in a nest hole high up on the rock a Great-horned Owl
in its nest preened two chicks.

Violet-green Swallows entered and left a nest box across
the field, sometimes perching on a wire, and small flocks of
White-throated Swifts frequently buzzed noisily overhead.

Small groups of Phainopeplas flitted among the trees in the
field, and a few showed up nearer to us further down the
trail, though they never sat still long enough to suit us.

This is the last WBU walk of the season.
Walks resume on October 3, 2009.

Mitchell Canyon, Mt. Diablo
Leader: Chuck Groff

The morning started out overcast and by the time we
arrived it was drizzling off and on very lightly. The group
was small, only seven people. As we started down the trail,
we began to see bird activity. Acorn Woodpeckers were
calling and visible, doves, finches, towhees were moving all
around us, and there was a cacophony of bird calls to hear.
There was so much activity that we stayed at the trailhead
for nearly an hour. Then as we started down the trail the
rain picked up and we decided to call it quits. We ended up
with a short list, but it makes up in variety for what it lacks
in quantity.

Thornton Delta Area, January 3, 2009

January 3, 2009
Wild Bird Unlimited Bird Walk
Near Thornton: Sacramento River Delta
Leader: Chuck Groff.

We had 23 birders and there were 8 cars meeting at
Westgate county park. It was a very beautiful day, sunny
and clear. But it was COLD. Generally, the birding was
poor. At the park we saw almost nothing. On Guard road
there were several fields each with many cranes.
Woodbridge road was very disappointing, a few cranes, a
few swans, a few kingfishers and all the waterfowl visible at
the major stopping place were so far away you could hardly
make an ID. Peltier road did have a few fields with more
cranes, but that was it.
