Albany Mudflats-McLaughlin Eastshore State Park-Albany Bulb

Editor’s note: If you’ve never taken the time to read a trip report, you are missing out. Please enjoy Fred’s report and this “snapshot” of a morning at the Albany mudflats.

By Fred Werner

On January 26th, 40 people showed up including seasoned experts, total novices and everywhere in between.  It was a mild day for January: mostly cloudy but with no wind, the Bay was glassy. We started the day scanning the mudflats, taking in the scattered American Avocets and other assorted shorebirds, coots and ducks. Multiple Red-tailed Hawks flew by but the foraging flocks didn’t seem too concerned.

Moving on to the uplands area of the McLaughlin Eastshore State Park, we got even better views of the Canvasbacks and some of the other ducks, and really nice views of a lone Mew Gull.

The biggest highlight of the day was the Burrowing Owl standing in fairly tall grass in the middle of its protected enclosure, patiently awaiting some excitement. For us, he was it!!!

As we rounded the curve at the west end of the Burrowing Owl area, most people headed for home. But a Red-throated Loon cruising along the flooded shoreline below us, beckoned us to continue. Three people joined the optional extension out to the tip of the Albany Bulb, beginning with a chase for the perfect view of that loon. These few intrepid birders were rewarded richly for their efforts.

Jutting a half mile further out into the Bay, the rocky spit at the tip of the Bulb was a refuge sought by large flocks of shorebirds as the tides rose, including quite a few we hadn’t seen yet today:  Black-bellied and Semipalmated Plover, Least and Spotted Sandpipers, Black Turnstones, a lone Black Oystercatcher, and one Eurasian Wigeon trying to blend in with a large raft of American Wigeons. The massive schooling flocks of Western Sandpipers also put on a spectacular show out there, as did the White-tailed Kites and the Osprey.

Enjoy Our Wintering Birds While You Can

Enjoy Our Wintering Birds While You Can

“While you can” refers to the next few months, after which our wintering migrant birds will depart to their breeding grounds elsewhere and be gone until fall. But it could also refer to the longer-run sustainability of bird migration patterns as our global climate changes. None of us knows when one or more migrating species might find it necessary to change their migratory patterns simply in an attempt to survive. White Storks that breed in Europe, for example, are already forgoing their traditional African wintering ground and choosing to migrate a much shorter distance within Europe. Perhaps some of the migrant species of birds that we can see today (and in the next few months) might not be returning in comparable numbers in future years. But they are exquisite to see and to appreciate now, while we are privileged to have them.

Bird species in one geographic location are generally classified into one of two categories: residents that are year-round, and migrants that are there for only part of the year. Within the migrant category, there are the birds that are generally there during the summer to breed but elsewhere during the winter, and the wintering migrants that arrive in the fall and leave in the spring to go elsewhere to breed. The focus of this post is on the wintering migrants (those here now). There are other more transient types of migrants as well: those that may regularly pass through our area on their way to their breeding and/or wintering areas (e.g. Hermit Warbler, Black-throated Gray Warbler), as well as “vagrants” that we don’t really expect but show up occasionally perhaps because they have gotten off course (e.g. a Summer Tanager seen from last October to January in the Claremont Canyon Regional Preserve). But back to the wintering migrants—it might be natural to think of them as visitors, but ornithologists think that they are descended from those who at one time were full-time residents of the winter grounds. In other words, the wintering birds are simply returning to their ancestral homes. More reason to appreciate them, I think.

What are the wintering species? I’m going to describe a few of my favorites, chosen to illustrate differences in migration patterns and the different parts of the world they rely upon in addition to our own.…

Misses Marked 2018’s Oakland Christmas Bird Count

Misses Marked 2018’s Oakland Christmas Bird Count

by Dave Quady and Bob Lewis

During the week preceding count day, forecasts of rain and high winds created a sense of
foreboding that continued into the early hours of Sunday, December 16, as early-rising
birders set out to seek owls. Along Telegraph Avenue few vehicles broke the silence and
ambient light bouncing off low clouds obviated the need for flashlights. Playing a bit of
tape elicited a single call from a distant Barn Owl. Moments later Berkeley’s City Bird
silently flew in and circled overhead, and so at 3:30 a.m. Oakland’s 78th annual Christmas
Bird Count got underway.

Thick cloud cover made dawn a non-event, but it nonetheless marked the usual ramp-up
of birding activity as teams met up in the field and began to bird their assigned areas.
Although winds gusted to 18 mph, the weather was mild during the morning:
temperatures in the 50 – 60 degree range, moderate winds and no rain. Our two boats
were able to get onto San Francisco Bay, 261 field observers provided good coverage
over the complete count circle and 34 yard watchers contributed mightily– producing, for
example, more than half of our record high 22 White-throated Sparrows. Rainfall began
about 2:15 pm, but by that time many teams had done their job, and by 3:00 p.m. most
folks had called it quits.

Our “good birds” of the day were a varied lot. They included single Long-tailed Ducks
from two different areas, a juvenile Ferruginous Hawk detected in two adjacent areas
(and chosen as the count’s Best Bird), 18 Snowy Plovers, 35 Surfbirds, a House Wren, a
Blue-gray Gnatcatcher, two Black-throated Gray Warblers (one reported by a yard
watcher) and a Western Tanager. Besides White-throated Sparrow, record-high numbers
(since 1974) were recorded for Cackling Goose, Green-winged Teal, Semipalmated
Plover, Great Blue Heron, White-tailed Kite, American Crow (2,486 birds) and Common
Raven (453 birds).

In recent years we’ve experienced a record-high count for one or the other of these two
corvids several times, so let’s examine their population trend. From 1974 through 1990
we averaged fewer than 200 total crows and ravens a year … over the following 10 years
we averaged more than 700 total crows and ravens annually, and since 2010 the annual
average has been nearly 1,800 birds. That has been quite a population increase, and
there’s no sign that it has topped out.…

We Are Not Powerless Against Climate Change

We Are Not Powerless Against Climate Change

World Wetlands Day February 2, 2019
and the Ramsar Convention

by Maureen Lahiff

Our San Francisco Bay is not only a designated Important Bird Area, it is a Wetland of
International Importance under the Convention on Wetlands, often called the Ramsar
Convention. This treaty on the conservation and sustainable use of the world’s wetlands was
put into final form on February 2, 1971 at a meeting in Ramsar, Iran.

Arrowhead Marsh by Rick Lewis

The Convention defines wetlands broadly, as “areas of marsh, fen, peatland or water, whether
natural or artificial, permanent or temporary, with water that is static or flowing, fresh,
brackish or salt, including areas of marine water the depth of which at low tide does not exceed
six metres.” The Convention places wetlands in a comprehensive and holistic context, but it
does recognize the key role of birds, as its full name is the Convention on Wetlands of
International Importance especially as Waterfowl Habitat. By waterfowl, the Convention
means any bird species ecologically dependent on wetlands. BirdLife International is one of the
five major partners.

Common Goldeneye by Bob Gunderson

The materials for World Wetlands Day 2019 emphasize the role of wetlands in “stabilizing
greenhouse gas emissions and blunting the impacts of climate change.”  Wetlands, especially
peatlands, are natural absorbers of carbon. More carbon is sequestered in peatlands than in
the world’s forests. As sea levels rise, wetlands can dampen storm surges and protect near-by
lands from flooding. As the materials point out, 60% of the earth’s population live and work
along coastlines. In sum, “Wetlands are a natural solution.”

Worldwide, we have lost about 70% of our wetlands, and the loss since 1970 has been
dramatic. Although we have lost 90% of the San Francisco Bay’s wetlands, we have been saved
from the disaster of a largely filled-in Bay, thanks to the courage and commitment of Esther
Gulick, Kay Kerr, and Sylvia McLaughlin, who founded Save the Bay in 1961.

The creators of the Ramsar Convention express confidence that wetlands can be conserved
and restored within a context of sustainable development. I would go even further: unless
wetlands are protected and restored, we cannot be successful in the sort of development
envisioned for the world’s people in the Millennium Development Goals and their successor
the Sustainable Development Goals.

Almost 90% of the United Nations’ member states are contracting parties to the Convention.…

Cinnamon Winter Beach Beauty

Cinnamon Winter Beach Beauty

By Miya Lucas

The Marbled Godwit is one of my favorite birds and one you can easily identify walking on a beach on a winter day in the Bay Area. Marbled Godwits are large, beautiful orange colored birds, easy to spot on the shoreline. They stand 18 inches tall, with long gray legs and their extended pencil-thin, bi-colored beak makes them easy to see. They are the largest of all the godwits. (Black-tailed Godwit, Bar-tailed Godwit, Hudsonian Godwit)

Marbled Godwit on the shoreline by Miya Lucas

It is unclear how the Marbled Godwit obtained it’s name. The “Marbled” part is easy to understand and it’s a good description of their tawny coloring, but the second part, “Godwit” is a mystery. From what I can gather, in Old English, god meant good, and wit or wiht, meant creature. In Spanish, they are called cinnamon needle, Aguja Canela.

The Marbled Godwit seems fearless to me,  I call them the gentle giant of the shoreline beaches. They seen unaffected by the often frenzy flights by the smaller shorebirds, sometimes hundreds of them who fly away –  startled by who knows what – then readily return to continue forging on the shoreline. Meanwhile, the Marbled Godwits, stand their ground and just continue feeding, grooming or sleeping.

The Marbled Godwits are social birds. Except for breeding season, you rarely see just one Marbled Godwit. They fly in flocks and will feed in flocks. With a one syllable high pitched call, they will let the group know if one is leaving or arriving. Their long elegant lines are often juxtaposed to their call, they have an annoying high pitch loud erking sound almost like a two year old ready to throw a tantrum.

Flock of Marbled Godwits by Bob Gunderson

Both sexes look alike, both have the bi-colored bills, pink at the base with a black end. However, the females have a bill about 2cm longer than the male. Also, the female weighs about 20% more than the male. Sometimes, if you are an astute observer, in early August you may see the Marbled Godwit in it’s breeding plumage.  During breeding season, the male’s bi-colored bill becomes more orange in color, although the black outermost tip remains the same, and the breast will be more barred.

The Marbled Godwit spends the winter along most of the Western or Eastern American shoreline, including Central America.…
