Bay Nature magazine recently ran an online column on what birds do in the rain, by San Francisco consulting naturalist Josiah Clark. We liked it so much that we’re reprinting it! (With permission of course.)

The sea gives birth to the storm and it’s the seabirds that feel it first. With instincts any sailor would envy, seabirds sense and flee from the storm front, often arriving in numbers days before the weather makes landfall. Larger pelagic birds somehow retain their independence from land, toughing out even the most raging of storms. In these conditions it is the smaller pelagic birds that are brought to the brink. With less mass and running on tighter energy budgets, murrelets, phalaropes, and the aptly-named Storm Petrels near land are signs of an uncommonly torn-up ocean beyond the horizon.

Closer to shore, gulls, pelicans, and loons stream south over wave and bluff in a darkening sky, avoiding the worst of the storm’s wrath. But when seabirds get unlucky, exhausted, and too wet, they are at the mercy of the current. At the Golden Gate on an incoming tide it means getting sucked into the Bay. This accounts for many of the only East and South Bay records for truly pelagic birds. Despite their remarkable instincts and endurance, countless seabirds of many types perish during extreme winter storms. But only a fraction of their corpses can be found at the high tide line after any big storm.

As for land birds, if the rain is not too heavy nor too cold, most birds will keep feeding. Stalwart Christmas bird counters regularly go birding in the rain, and there is often sustained activity with plenty to look at even in heavy rain if you know where to look. But what happens to them when it’s pouring, say, for days?

The water-shedding micro-structures of flight feathers shed droplets off the birds’ back. An oil gland at the base of the tail helps keep the feathers zipped up water-tight. The inner insulating layers of down feathers are kept dry and able to be fluffed up with air, holding in body heat.

If I were a bird I would want to go inside a dry stump. As it turns out, only birds that nest in cavities are likely to have that luxury. Flocks of Pygmy Nuthatches pack into chiseled holes in dead snags like clown cars, where they seem to embody the meaning of “cozy”.…

Birders quickly learn to use bird bills to help identify species. Bird tongues, if we could easily see them, would also be helpful in identifying species. This blog is to whet your tongue about bird tongues and highlight the diversity that evolution has brought to avian tongues.

First, most birds have pretty prosaic tongues. They look somewhat similar to ours but can have some interesting extra features. As shown in Figure 1, the tips can be fringed or split and the root of the tongue may have backward-facing barbs. It is not clear if the fraying or splitting helps in acquiring and eating food, but the backward-facing barbs are useful for moving food to the gullet. This is needed because birds don’t swallow the way we do. These tongues vary quite a bit in width, thickness, amount of fraying, barbs and their placement, etc. (Note: Drawings are not to scale.)

Species such as woodpeckers and hummingbirds have more interesting tongues.  Most of these birds have tongues that can extend far outside their bill (Figure 2).  For these birds, the boney/cartilaginous apparatus that supports the tongue wraps around the skull under the skin, usually terminating in the right nostril (Figure 3).  Extending their tongues lets hummingbirds reach into flowers for nectar or lets woodpeckers get insects from crevices in trees.

In the case of woodpeckers (Figure 4), the tip of their tongue can also be barbed or covered in sticky fluid that helps them capture insects. Sapsuckers have shorter tongues with hair-like structures for gathering sap from trees.

Birds that filter out food particles from mud and water have the most complicated-looking tongues.  Their tongues have papillae (barb-like or hair-like structures) of various sizes and shapes that help strain out food particles.…

The Bay Area’s welcome rainstorms let up for 24 hours on Sunday… just long enough for more than 200 birders to have a fabulous Oakland Christmas Bird Count.
Sunday December 14 marked the start of the 115th year of Audubon Christmas Bird Counts, and the 74th such count in Oakland.
Registration in advance came to 287 people, a new record for Oakland. Last year the Oakland count was the fourth largest in North America, and this year’s count is likely to be in the top five again.
With logistical planning that practically rivaled D-Day, count organizers Bob Lewis and Dave Quady sent 29 teams out into the field to tally birds on the bay and shoreline, on hilltops and in ravines, at cemeteries, college campuses, parking lots, city streets, and golf courses.
Then about 130 participants gathered to celebrate and compare notes over dinner at Northbrae Community Church in Berkeley.
The preliminary, incomplete tally was 176 species — short of the Oakland record of 183, but still a respectable total.

Notable this year were large numbers of Acorn Woodpeckers and Varied Thrushes, species that are not typically common in most of the Oakland count circle. The Tilden North count team spotted 74 Varied Thrushes, while Tilden South spotted 118!
“There were Acorn Woodpeckers all over,” count organizer Dave Quady said. “It’s probably due to some combination of a prolific breeding year and a shortage of acorns east of us” (where the birds are more typically found).
The count was featured in vivid news coverage by the San Francisco Chronicle, Contra Costa Times, and Channel 7.
It drew both longtime birders and people who were new to the CBC.
On the longtime end of things, the Merritt College team was made up of Anthony Fisher, his two brothers, and his nephew. The Fishers grew up in that neighborhood and used to bird there as kids when Campus Drive was a meadow rather than a subdivision.
“It was a rolling meadow above the quarry, with snags and Western Bluebirds nesting in them,” Fisher recalled.

On the newer end of things, this was the first count for Susanna Kwan, who started birding last January and joined the Mills College count team.…

The longtime skipper of the North Boat, Ed Jepsen, was an excellent sailor and navigator, and even taught classes for the U.S. Coast Guard. However, one day many years ago, we sailed into a phenomenon that could have led to the death of Ed’s then-wife.
It was a clear and cold day for the Oakland Christmas Count, and the North Boat was headed north from the Bay Bridge paralleling the eastern shore of Treasure Island.
Ed’s wife loved the outdoors and birds and had come to love being out in the Jepsens’ boat. But by that time her health confined her to a wheelchair, where she was enjoying the expansive view from the back deck.
Suddenly, the prow of the North Boat lurched substantially upward into the air as we emerged from the calm waters behind Treasure Island and encountered a very strong rising tide coming into the Bay from the Golden Gate.

We all grabbed onto something to steady ourselves. But right away I noticed that the wheelchair did not have its brakes fully engaged and was rolling rapidly toward the rear of the boat — with Ms. Jepsen in it.
I remember jumping and grabbing the arm of the wheelchair. Fortunately one of our other bird spotters did likewise, just before it hit the back railing, where it could have thrown Ms. Jepsen out and into the water.
We could hardly believe what had happened and how fortunate we were that a tragedy had not occurred. Naturally our minds were at least temporarily off of counting birds.
Another extremely memorable North Boat experience took place on another cold, clear day that was quite windy. We had rounded the south side of Yerba Buena Island and passed under the Bay Bridge heading north on the San Francisco side, scanning the small rocky beaches at the base of the island’s steep cliffs for birds.

Suddenly, Pete White called out that he had seen something strange on the beach that looked a little like a human body. He asked Ed Jepsen to come about and get closer, so that we could better see what was on that small beach.
I ran over to the railing and, sure enough, my binoculars showed a dead body washed up on the beach.…

Breeding Birds of Solano County is a breeding bird atlas like no other breeding bird atlas you’ve ever seen.

With a glossy, photo-filled hardcover format and and a weight of over five pounds, it is as beautiful as any coffee-table art book produced by a museum.

Just published by Napa-Solano Audubon Society, the atlas would make a splendid holiday gift not just for birders but for anyone with an interest in California nature.

It provides descriptions of historic range, breeding behavior, and conservation status for 151 birds that nest in Solano County. It also offers 350 color photos by sixty Bay Area bird photographers, including 44 images by GGBA’s own board member and birding instructor Bob Lewis. And it has detailed color maps for each species, created by GGBA instructor and mapping professional Rusty Scalf.

If you’re not familiar with the concept of a bird atlas, the concept originated in Britain in the late 1960s — a systematic guide to birds that nest in a particular area.

The idea spread to the U.S. and Canada. On the East Coast, breeding bird atlases often cover an entire state. In California, they typically cover one county. The past 30 years have seen publication of atlases for Alameda (2011), Contra Costa (2009), Santa Clara, and Marin counties, among others.

The Solano atlas had its genesis a quarter of a century ago when birder Robin Leong approached Napa-Solano Audubon Society to create a volume covering Solano County. But the group could only raise enough funds for a Napa atlas. They did field work from 1989 through 1993, and finally published the Napa volume in 2003.

Solano then got its turn. Volunteers – including some GGBA members like Dave Quady and John Luther — conducted field surveys from 2005 through 2010. Organizers were determined to avoid another ten-year lag between field work and publication, and so in early 2013 ornithologist Murray Berner started writing the species descriptions and editor Mike Rippey started compiling photos.

Then came the logistics of publishing, which ultimately led to a printer in, of all places, Italy.

“People who will bind and make books in the U.S. are a dying breed,” Berner said. “The board didn’t want to go to China, and the U.S.…
