Location, location, location! But for a fenced-off dilapidated navigation light stand on a jetty at the Seaplane Lagoon, Ospreys would not have had a successful nesting season at Alameda Point in 2016.
In late August, two adult Ospreys took flight from their Seaplane Lagoon perch for parts unknown with two healthy offspring. It was a welcome sight because for the past three years a series of frustrating avian soap operas featuring other Ospreys and unwanted nesting attempts aboard the maritime ship Admiral Callaghan were marked with failure. Previously in 2012 they had raised one chick, the only other recorded case of Osprey reproduction at Alameda Point.

The Ospreys briefly attempted to nest this year on a parking lot light pole on the wharf near the USS Hornet. But a pair of ravens repeatedly harassed the Ospreys, even stealing nesting material and tossing some of it on the ground. The Ospreys finally found peace back on their original nest from years ago that still straddles the top of the light stand at the entrance to the Seaplane Lagoon. The navigation light stand, erected in 1940, is at the tip of the rock wall jetty on the west side of the lagoon.
This year’s nesting effort was aided by the installation of a fence across the foot of the jetty where the nest sits to keep curious individuals from wandering out near the nest and causing the birds to leave the nest. The fence was erected by the city at the urging of local osprey watchers.

“Frequent disturbances can cause anxiety in wildlife that interrupts normal behavior,” said Leora Feeney, a longtime advocate for Alameda wildlife with Golden Gate Bird Alliance. “Having birds leave the nest, even for a few moments, provides an opportunity for gulls, ravens, herons, or others to prey on eggs or chicks.”
More help is needed in order to maintain this unusual raptor nest site. Three of the iron legs on the light stand are rusted through and won’t hold up the bulky Osprey nest much longer. Years ago its mate on the other side of the lagoon entrance toppled over and is hanging by a chain at water’s edge.

“Adorable” is how my wife Susan once described the Bewick’s Wren, and even non-birders would agree with the aptness of the description. These wrens are brown on their backs, wings, tails, and heads, and grey on their bellies. The bill is curved, the tail is long, and the outer tail feathers show white.
Most distinctive is the long, pronounced white eyebrow that helps to distinguish the Bewick’s from the House Wren that it most resembles in the west and southwest. This eyebrow gives it a cocky appearance—contributing to the “adorable” effect. Bewick’s are small, slender birds, averaging a bit over five inches in length and weighing only about a third of an ounce. But their size is belied by their bold character.
Their boldness is perhaps most evident in their song. For such a small bird, the Bewick’s Wren has tremendous vocal range and power. A male bird can have up to sixteen different songs. They can be tireless, too: In early spring, singing can take up to half of the male’s time. It’s no wonder that one of the names for a group of wrens is a “chime”—the others being a flock, a flight, and a herd! On a recent bird walk in the Oakland Hills, Golden Gate Bird Alliance birding instructor Bob Lewis said that when you hear a bird you can’t immediately identify by song, Bewick’s Wren is often the right guess. I’m becoming more familiar with my resident male’s repertoire, but he is still capable of fooling me on occasion.

Primarily a New World species (the only exception being the Eurasian Wren), the Bewick’s Wren, Thryomanes bewickii, was first collected by John James Audubon in Louisiana in the winter of 1821. Audubon named it after the English naturalist Thomas Bewick, whom Audubon met during a visit to England in 1827. Bewick was by then 74 years old and famous for his book A History of British Birds, recognized as a forerunner of modern field guides.

The Bewick’s was formerly beloved as the “house wren” of the Appalachians and the Midwest, but the species today has almost disappeared east of the Mississippi. Ironically, competition from the actual, later-arriving House Wren has been partly responsible for its steep decline in the east and parts of its traditional range in the west.…

On September 12, the San Francisco Board of Supervisors’ Land Use Committee will hear a proposed resolution seeking expanded public access to the Peninsula Watershed Lands. It urges the San Francisco Public Utilities Commission (SFPUC) to provide enhanced public access to existing roads and trails in the Watershed Lands, consistent with the goals of protecting the water supply and the environmental quality of the area.
Sounds like a wonderful idea … except when you look into what this means for our drinking water supply, native plants, and wildlife.
Golden Gate Bird Alliance opposes this resolution or, at a minimum, calls for postponing any decision until the SFPUC has completed its study on the impacts, costs, and funding for opening the watershed. We believe the wording of the resolution itself is contradictory. How exactly does opening up the watershed lands protect the water supply and the environmental quality? It will not. Opening public access to our watershed will have environmental impacts – especially impacts on our drinking water, native plants, birds, and other wildlife – that must be considered.

Protected since the 1860s

The Peninsula Watershed is a 23,000-acre area surrounding Crystal Springs Reservoir, bordered by Pacifica and San Bruno in the north and Woodside and Redwood City in the south. (See map at bottom of this article.) As a source of drinking water for the city of San Francisco, it is owned by the PUC and has been closed to the public since it was originally set aside in the latter half of the 1800s. The watershed is part of a regional water system serving 2.6 million people in four San Francisco Bay Area counties. About five percent of San Francisco’s drinking water comes directly from rainfall and run-off into the Peninsula Watershed reservoirs. In addition, some Hetch Hetchy water (which makes up 85 percent of the city’s water supply) is stored in the Peninsula Watershed reservoirs on its way to the city.
The watershed is critical, intact habitat for 800 plants and trees, 165 bird species, 50 mammal species, and other wildlife – many of which have been extirpated from other parts of the Bay Area. This watershed has the highest concentration of special status (rare, threatened and endangered) species in the entire nine-county Bay Area.
The Peninsula Watershed is a California-designated Fish and Game Refuge and protected under the UNESCO Golden Gate Biosphere.…

Capping a season of successful heron rescues and public education, Golden Gate Bird Alliance joined with partners International Bird Rescue and Oakland Zoo last Friday to release seven rehabilitated herons and egrets back into the wild.
We released three young Black-crowned Night-Herons and five Snowy Egrets into the protected marsh area at Martin Luther King Jr. shoreline — a marsh that GGBA helped save from development over the past several decades.
It was an inspiring moment, and one that was captured by media including the San Francisco Chronicle, ABC7, KTVU, KCBS Radio, and the Oakland Tribune. There is nothing like watching birds that have been injured and nursed back to health peer out of their carrier boxes, take a step or two, realize they are no longer in a pen, and spread their wings to fly freely.
Friday’s release was the culmination of our work during the 2016 nesting season protecting and educating people about the heron and egret rookery in downtown Oakland.
All told, we saved the lives of 21 young herons that would otherwise have died from injuries, traffic, or exposure!

This effort began two years ago, after a highly-publicized incident in which Black-crowned Night-heron nests were destroyed by tree trimmers hired by the downtown Oakland post office.
We responded immediately by publishing a brochure in English and Spanish on how to care for trees without harming birds or nests. (You can download the brochure here.) Last year, we broadened our educational initiative by a adding volunteer heron docents, guided bird walks through the rookery, and posters about herons in English and Chinese.
This year, we expanded the docent program and added the rescue component. Twenty-four GGBA volunteers monitored the rookery, counting the nests, explaining the heron colony to passersby, and watching for fallen and injured young birds.

They documented 149 nesting pairs of herons and egrets in central downtown Oakland — 120 pairs of Black-crowned Night-herons and 29 pairs of Snowy Egrets! With each pair producing two to three young, that is a very large rookery — in fact, the second largest night-heron rookery in the Bay Area.…
