A SOUTH BAY ALBUM

The May meeting of GGAS will feature photo- grapher Tom Rountree. Tom is, perhaps the most rapidly rising star of Bay Area wildlife photo- graphy. For our meeting Tom will present a show called “A South Bay Album” which includes waterbirds and shorebirds of our South Bay wet- lands and salt ponds. No one else captures the essence of these birds as Tom does. He has been specializing in their photography for years and the results are truly wonderful. We will see slides of these birds accompanied by a soundtrack com- bining music and narrative. It is a show not to be missed. And, of course, Tom will be there to answer questions.

As an added treat, Roy Lowe, naturalist for the San Francisco National Wildlife Refuge, will continue our journey through the SF Bay wetlands with his own slide presentation. We will learn of the great habitat values of these wetlands and of the present day threats to their existence.

Refreshments, as usual, will be served and we do hope you can come. The meeting will be on Thursday, May 9 at 7:30 p.m., at the Northbrae Community Church, 941 The Alameda, Berkeley. See you there!

CES

WINE, CHEESE AND COOKIES ON RICHARDSON BAY

Mark your calendar! Sunday, June 2, is the date of our annual meeting. Between the hours of 2 and 4 p.m. we will have a fantastic wine and cheese tasting at the Audubon Western Education Center on Richardson Bay. The lovely, recently restored Lyford House is an ideal setting for this very fecial occasion. We will honor fellow conserva- ^nists, raise funds for our sanctuary, and cele- l^ate the beginning of a new year for Golden Gate .^udubon Society.

Fine California wines will be selected and do- ated by GGAS member and friend, George Pey- in. An array of fine cheeses from around the I orld, and cookies, brownies and truffles from around the Bay will help clear our palates. If you wish to make a donation for the cheese or con- tribute baked goods, please call the office and let us know.

OBSERVATION REPORTS REQUESTED

The California Dept, of Fish and Game is gathering information on

the Black Swift, the Bank Swallow and the Purple Martin to document dis- tribution, abundance, habitat require- ments and reproductive success. It is also interested in documenting threats to these species’ habitats.

Please send reports of recent sight- ings (within the past decade) of breed- ing pairs of these species to Ronald Schlorff, Fish and Game, Nongame Wildlife Program, 1416 Ninth St., Sac- ramento, CA 95814. Include, please, your name, address and phone num- ber. Provide the following: location of sightings (if possible, legal description of nest territory - township, range, section - ideally a copy of the topo- graphical map should be included), date of observation, behavioral notes, and any other relevant information. This will help plan for protection of these species of special concern.

OBSERVATIONS: Through March 24

Although the spring northwest winds activated the upwelling and started the Farallon seabirds nesting early, the pelagic red crabs remained a maj- or gull food (PRBO). Millions of these crabs beached and died on Monterey beaches, providing a prolonged feast for huge concentrations of gulls (mob). The landbird migration on SE Faral- lon also began early (PRBO).

FORK-TAILED STORM-PETREL

The concentration of Fork-tailed Storm-Petrels in and around Monterey Harbor after the storms continued into early March. This happened in many previous Marches, but this month’s “wreck” (beaching and mass die-off of seabirds) reached unpre- cedented proportions. Thirty were at Monterey Harbor March 2 (GW) On

THE GULL

85

March 4 an incredible 1000 was esti- mated (SH). Live birds were last pre- sent March 7(AB) and many (most?) died; that day over 120 were found dead on one mile of Monterey Beach (RB). About half of these were picked up for preservation in museums (RB, SFB). All 59 prepared by California Academy of Sciences were emaciated (SFB).

Meanwhile, small numbers of Fork- tailed Storm-Petrels appeared at other coastal sites. On March 2 about four were inside Bodega Harbor (DS, MD) and one was picked up at San Pedro Valley Park, Pacifica (SS). The next day one was inside Princeton Harbor (CR, ME). Ten were seen off the Santa Cruz Wharf March 4 (RT). Three more were three miles off the southern Marin County coast March 3 (ES). Farther offshore from Mon- terey, where healthy individuals might be more expected, only one was seen March 9 (SFB, SJ).

We know essentially nothing about why only certain storms contribute to wrecks, or about the causes of many wrecks that occur in the absence of storms. The pelagic lives of seabirds remain largely mysterious.

OTHER WATERBIRDS

Twenty Black-vented Shearwaters were still off Monterey March 9 (SFB, AB, TC, SJ). A flock of 56 Cattle E- grets was about four miles west of Los Banos Refuge March 8 (TC). Else- where a scattering of Cattle Egrets lingered into March.

The Eurasian form of Green-winged Teal was spotted at Sacramento Na- tional Wildlife Refuge March 24 (GF, et al.) The male Harlequin Duck at Moss Landing stayed at least to March 23 (CS, et al.). Another male Harlequin Duck frequented both sides of the beach at Rodeo Lagoon from

March 16 (DK, CF). On March 20-21 a female was with him (CF).

Princeton Harbor,s Rock Sandpiper remained through March 23 (PG, et al.). Increased scrutiny of Merced National Wildlife Refuge proved that there were two different Ruffs March 2-3 (GF, et al.). One was still there March 9.

At Stockton Sewage Ponds it was not “news” that the adult Little Gull, adult Common Black-headed Gull, and first winter Franklin’s Gull were seen again March 5 (JMS, et al.). The Little Gull was also seen March 24, when the surprise was discovered ; a first winter Common Black-headed Gull (both JP). The Franklin’s Gull at Napa Valley College was reportedly present on March 5. Glaucous Gulls at Palo Alto Dump and Princeton Harbor were last reported March 3 (TC) and March 12 (DS), respectively. Another Glauc- ous Gull was seen across Tomales Bay from Inverness March 1 (MD), and one arrived on SE Farallon March 4 (PRBO). Three Black-legged Kitti- wakes were reported from the Bay shore at Burlingame March 1 (DS). Were these related to the wreck of storm-petrels? Monterey waters have held gradually increasing numbers of Kittiwakes this winter (mob), but it was a shock to find 2000 on March 9, mostly in a series of massive feeding aggregations off Moss Landing (SFB, AB, SJ). At SE Farallon, numbers grew to 400 on March 5 (PRBO).

LANDBIRDS

The Spotted Owl remained at Mer- ced National Wildlife Refuge through March 15 (mob, KH). The Greater Pewee lingered at least to March 7 (JL). A yellow-billed Magpie was at Coit Tower in San Francisco March 1 (RA). Especially in such a location one suspects a captive origin rather than a vagrancy for this species. The

86

THE GULL

riprap of Candlestick Point was a strange place for a Rock Wren March 17-24 (AH, et al., JMu), but in this case the bird probably wandered there on its own. Without firm evidence our judgments on a bird’s origin are merely guesses as to relative proba- bilities. They are educated guesses, however, and knowledge of a species’ life histories and susceptibilites to captivity often determine our attitudes toward anomalous “strays”. Middle Lake’s “Baltimore” Northern Oriole was seen again March 2 (JM, et al.).

Dr. Bailey received a letter from Peter H. Gleick of UC Berkeley, dated Feb. 20, 1985, which we print because of its interest:

“I am sorry to have to send in the following observation. This afternoon, my wife and I were birding in Tilden Regional Park between 2 and 4 p.m. The day was warm and clear and we were approching the intersection of the Nimitz Way on the trail up from the Tilden Environmental Nature Cen- ter. We stopped and sat for a while and noticed three Red-tailed Hawks to the west toward the Bay. One, ap- parently a female, was perched on the tower of one of high-voltage power lines that run approximately north- south through that section of the park. The other two, apparently males were engaged in a classic courting battle, including full contact, the locking of their talons and “helicoptering” down nearly to the ground. They broke con- tact and regained altitude. One flew to the top of the tower and landed near the female. At this point, the other male dived from well above, hit the sitting male, and, clutched toget- her, they started to circle down to the ground. Then one hit the high-voltage line and (I guess) the other hit the tower itself. There was a tremendous flash, an extremely loud “bang”, and both birds plummeted to the ground, obviously instantly dead, both burning. There was smoke for several minutes from two small ground fires. The fe- male flew some distance and then re- turned to the top of the tower where she remained for as long as we watch- ed.

“Although I know that such deaths occur, my wife and I were both struck to the heart by witnessing this tra- gedy, particularly since we were im- mensely enjoying the courting display

—itself rarely seen in such full splen- dor. Watching the courting display, which naturally ends in birth and life, only to see it end unnaturally in death, was a horrible experience. I guess that birders, by their very nature, are observers. We watch and we see— but I hope never to see this horrible event again.”

CONTINUED CONDOR PERIL

The California Condor remains in grave peril. Against the advice of GGAS, the Friends of the Earth and the Sierra Club, the Condor Recovery Team has removed all eggs and fledg- lings from the wild during the past two breeding seasons. Two years ago GGAS proposed a balanced recovery plan to the Dept, of Fish and Game. It suggested assuring both captive and free flying populations by allowing some condors to raise their young in the wild. That proposal was ignored. Now it seems disaster struck last win- ter; four birds are unaccounted for. This brings the population of free- flying condors to eleven or twelve with as few as two breeding pairs. Sixteen birds are held in captivity. Had the wild population remained stable, the Recovery Team was expected to re- lease three captive reared birds this year. That plan is now in question, and the removal of all remaining wild con- dors is under serious consideration. It seems that the Condor Working Group, representing primarily the San Diego Zoo and the Los Angeles Zoo, is the proponent of this proposal. The Working Group is expected to bring it to the US Fish and Wildlife Service to try to alter the recovery plan to allow the capture of all California Condors. It has been suggested that Andean Condors should be released in southern California to act as re- search surrogates while .the entire California Condor population is held in “protective custody”.

As the condor population plummets, the US Forest Service, guardian of much essential habitat, is considering massive development plans which would doom the condor if brought to fulfillment. The 6000 acre Peppermint

88

THE GULL

Mountain Resort Project in Sequoia National Forest would certainly im- pact our nation’s most endangered species. Plans call for an access road 1.2 miles from a known nesting site. The Draft Environmental Impact Re- port ignores any impact on condors Of other animals which do not use the actual development site. At the same time Los Padres National Forest is considering oil and gas leases in a number of critical habitats including the Sespe Condor Sanctuary, at least two nest sites, various roosts, foraging areas and flyover areas. GAS opposes these projects.

Meanwhile, the planned Hudson Ranch National Wildlife Refuge has been in limbo for the past several months. The ranch is considered the most vital condor habitat in private ownership. It appears US Fish and Wildlife is assuming a wait and see posture before committing funds for its purchase.

National Audubon seems, finally, to see the point GGAS has been making for several years. Glenn Olson, Dir- ector of National’s Sacramento Re- gional Office, assured me the Condor Recovery Team plans to oppose the Condor Working Group proposal to capture all free flying condors,, and that it is important to protect the wild population and its habitat. Glenn also said the Recovery Team plans the scheduled release of the three captive reared birds this year.

There is no doubt; the California Condor is America’s most threatened species. There seems little we can do to protect this most majestic master of the skies. However, if you are as concerned and frustrated as I am, please send me a letter or postcard and I will forward copies to appropri- ate agencies and National Audubon

President Russ Peterson. It is easy to forget, so jot a note right now saying you are concerned about the future of the condor and send it to: Califor- nia Condor, GGAS Office, 1550 Shat- tuck Ave., Berkeley, CA 94709. There are 5800 members of GGAS and we can have an impact on this and other issues if we act. Voice your concern.

- DAN MURPHY, President

At the April 6 Bay Area Audubon Council meeting Dan Taylor, National Audubon representative, reported two more condors are unaccounted for at the present time, and one of these is a paired bird. It would appear that there is only one remaining pair of breeding California Condors. The pos- sibility of poaching or poisoning must be considered.

CONSERVATION NOTES

Wetland Protection In Briones

The GGAS-Sindicich Lagoon fence is up! Last year the GGAS board voted $5000 from the Society’s Sanc- tuary Fund to provide for construction of a fence around the Sindicich Lagoon in Briones Park. Its purpose is to pre- vent cattle from trampling the shore- line vegetation. This will allow aquat- ic plants to be re-established, enhanc- ing this habitat for waterbirds, small mammals and the famous Briones newts. Visit Briones, hike to the ridge- tops and explore the grassy slopes a- round the logoons. The unobtrusive fense does not exclude humans, so be sure to search the shallows to see the newts.

Thanks to Neil Haulik, resource an- alyst, and EBRPDistrict for an excel- lent design and construction job. We

will dedicate the fence to the Makower family for their generous donation to the GGAS Sanctuary Fund.

Mono Gull Study Threatened

Since 1983 Point Reyes Bird Ob- servatory biologists Dave Shuford and Gary Page have studied the breeding biology of California Gulls at Mono Lake. Their research is a continua- tion of David Winkler’s study (1976- 82 ) and is crucial for an understanding of how the declining lake level affects the survival of these gulls at Mono. This season, however, PRBO will be forced to drastically cut back their research plans because of a lack of funding.

This funding crunch exists in spite of the fact that May (12 months ago) Gov. Deukmejian signed into law a bill by Assemblyman Norman Waters (D-Plymouth) which provides $250,000 for the “scientific study of the effects of water diversions on the Mono Lake ecosystem”. The statute authorizes the California Department of Fish and Game to contract with institutions to carry out the necessary studies. Yet due to apparent slow moving official machinery the anticipated funds for PRBO have not materialized.

Anticipating this, in February the GGAS board of Directors voted $1000 to PRBO to purchase and place gull decoys on Negit Island last March. Negit Island held the main nesting colony until 1979 when the declining water level exposed a landbridge con- nection to the mainland. This forced the gulls to abandon the island.. The landbridge is now covered by six feet of water following several winters of heavy snowfall in the Sierra. With Negit Island gain cut off from the mainland hopes are high that the gulls will return and the decoys were to help lure them back.

Letters are needed. They should go to Assemblyman Norman Waters, State Capitol, Sacramento, CA 95814, and should point out that his bill (AB 1614) requiring funding of research at Mono Lake is being ignored by Fish and Game officials.

Edgewood Park - Last Chance?

San Mateo County’s Edgewood Park has the finest display of spring wild- flowers in the Bay Area and for many miles beyond. It also is the site of over 70 species of birds. This spring may be your last chance to see this spectacular display because San Mateo Co. is considering turning it into a golf course. Although the height of the season is mid-April there is still plenty to see in early May. Do your- self a good turn and see it. The park is undeveloped, though there are trails It is un-signed, but it is easy to find. Take Rte. 280 south to Edgewood Rd. exit and go west on Edgewood a very short distance and park under the freeway underpass. Across Edgewood Rd. on the south side will be a fenced path leading into the park. As you walk under another freeway structure on a dirt trail look for swallows There are trails wandering by a stream through fields of wildflowers and also a trail going up an oak cover- ed hill. Once you have seen it you will want to help save it. Call and we will help direct your efforts. You may call Arthur Feinstein at 282-5937 or the GGAS office 843-2222.

A Mission Creek Wildlife Park in San Francisco

Where can you observe grebes cor- morants, night herons, a nesting egret and a Great Blue Heron just one mile from the financial district? Mission Creek Channel, ebbing and flowing

THE GULL

past the China Basin Building and un- der Blanche’s Restaurant, two draw- bridges, a houseboat neighborhood and 1-280, is home to numerous birds, fish, shellfish and other Bay species. This sheltered tidal inlet is the last remnant of historic Mission Creek which once flowed from just north of Twin Peaks past Mission Dolores. But water lots were granted to the railroads by the State, the Bay filled in, and Mission Creek Channel now lies within a 200- acre site proposed for development by Santa Fe Realty Corp.

Despite naming their project “Mis- sion Bay”, the developers’ current plans show no understanding of the importance of wetlands and no provi- sion for any wildlife habitat. Fortun- ately, something can be done.

The Mission Creek Conservancy, a non-profit corporation, formed two years ago to work for preservation and enhancement of the Channel’s tidal ecosystem has, with funding from Gerbode, Columbia and the San Fran- cisco Foundations, developed a Mis- sion Creek Park Master Plan. The proposal, prepared by Asian Neighbor- hood Design under the direction of architect Tom Jones, calls for enlarge- ment of the 24-acre waterway to 51 acres and the inclusion of 44 acres of land for a total 95 acres of park. Ac- cessable to the public and helping to meet the open space needs of the park-deprived South of Market area, the park would offer a variety of rec- reational opportunities (strolling, cas- ual play, birdwatching, fishing, boat- ing) as well as wildlife-only islands to shelter our resident fauna and pro- vide a resting place on the Pacific Flyway. Water edges would be planted with native species, re-creating the Bay marsh ecosystem once so preva- lent on San Francisco Bay’s shore.

Rather than oppose the Mission Bay development, the Mission Creek Con- servancy seeks to work with Santa Fe Pacific and the Department of City Planning, educating them to the importance of preserving the Bay ecology and showing them that a re- gional-scale natural shoreline park will benefit the whole development and the rest of the City.

Clean Water Act

After failing to pass in Congress last term, the Clean Water Act is now up for reauthorization before the 99th Congress. The act expired in 1982 but has stayed effective through continu- ing resolutions. Audubon lobbyists are working for amendments to strengthen water Bills S53 and HR8 introduced this year by Senator Robert Stafford and Representative James Howard.

Letters are needed urging Senators Wilson and Cranston to endorse the stronger Clean Water Act with amend- ments providing more protection for groundwater, bays and estuaries, and better control of pollution from toxics and runoff. In particular, urge both

THE GULL

Senators to strengthen Section 404 of the Act which would increase pro- tection of wetlands rapidly disappear- ing from the Bay Area.

Letters should be addressed to the two California Senators at the New Senate Office Bldg, Washington, D.C. 23510.

Birdseed Sale Report

The February seed sale was again a success. Nine hundred dollars was raised and the money was allocated to support conservation efforts. In this instance the funds will be used to help preserve Cullinan Ranch, a diked bay- land in the north Bay integral to the San Pablo National Wildlife Refuge and the Napa Marsh (rated by the US Fish and Wildlife Service as a- mong the six most important wetland areas in the US). This area is now threatened by a residential develop- ment of 4500 upper-income units with devastating impacts on the surround- ing wildlife.

We would like to thank all who worked on the sale and all who bought seed. Thanks, also, to Merritt Ander- son, our supplier, who devotes much effort to our sales. In addition during the month of May, Merritt will give all GGAS members a discount of 10% on birdseed bought at his store (bring your GULL as identification). The store is Oh’s Fine Foods (Calif. Direct Imports) at 2651 Mission St. (between 22nd and 23rd Sts.) in San Francisco. And remember, we’ll have another seed sale in late October, just in time for our visiting winter migrants.

THE GULL

THE BACK YARD BIRDER

Have you ever wanted to soar like an eagle? I have. Lacking the courage to fling myself off a cliff and hang- glide or the nerve to leap from an airplane and free-fall before parachut- ing to a “soft” landing, I did the saf- est thing: I went on a glider flight. It was wonderful and quiet and quite wierd to look down on hawks and vul- tures! It also was a perfect illustra- tion of the method of thermal soaring used by buteos, eagles and vultures. Today I saw six Red-tailed Hawks soaring in a tight circle, climbing higher and higher on a thermal and was reminded of the glider flight.

Columns of warm air are generated here and there from the earth’s sur- face. As the column rises it expands toward the top and is finally set free by the surrounding cold air. It’s simi- lar to a bubble of air rising from the bottom of a pan of boiling water. A continual updraft of cold air is en- circled by warm air. Birds ride the ring of warm air until they reach the desired altitude when they soar off in the desired direction. When they get too low, they search for another ther- mal and repeat the whole procedure. Since little energy is expended, this is a very efficient method of flying for birds who must search for prey over a wide range or who migrate long dis- tances.

The three main requirements for soaring successfully are: large size light wing-loading (the weight of a bird in pounds borne by each square foot of its wing surface) and maneu- verability (the ability to make tight circles or to change direction sudden- ly).

Since thermals are not generated over water, migrating soaring birds

must skirt large bodies of water, mak- ing certain areas such as the Marin headlands great spots to watch ther- mal soaring in action. When a large group of birds enters a thermal, the group swirls up and when one bird leaves the spiral it is followed by the remainder in a line. Such whirlpools of birds are called “kettles” in North America.

Another type of soaring occurs where air currents are diverted upward after meeting a surface. Winds hitting a cliff face are deflected upward and birds can sail along the edge of a pre- cipace, effortlessly suspended by these updrafts. In the east. Hawk Mt. Sanc- tuary in Pennsylvania is a famous spot to watch migrating hawks use this method of soaring. Seabirds use a similar method of exploiting the up- drafts over sea waves. Also, gulls ride the slipstream created alongside the gunwales of large boats.

Assisting the Red-tailed Hawk and other buteos is a broad, fan shaped tail which is not only used as a rudder but which provides an extra lifting surface from soaring. In contrast, ac- cipiters such as the Cooper’s Hawk, have short, rounded wings and long tails, so their flight pattern is quite different. They fly with rapid wing- beats and use only small amounts of gliding.

On cold, damp, foggy days soaring birds are “grounded.” They can be easily observed on fence posts and power poles while waiting for the air to warm sufficiently to form thermals. Since they can’t spy their meal through the fog from above, they are content to hunt from a perch.

If I were a bird I’d like to be a member of the thermal soaring spe- cies, surveying the world from on high, racing with the wind on stormy days, or hanging lazily in the cooler

Reservations are necessary so we can plan adequately. The tax-deducti- ble donation for this event is $15 per person. Checks should be made pay- able to GGAS and sent to our office at 1550 Shattuck Ave., Berkeley, CA 94709. If you are unable to make res- ervations by May 24 please follow up by phone.

Once again the proceeds from this fund-raiser will go to support Audubon Canyon Ranch, the sanctuary spon- sored by Golden Gate, Marin, Sequoia, and Madrone Audubon Societies. If you haven’t already done so, pack your best picnic lunch and visit the Ranch soon. It is three miles north of Stinson Beach on Hwy. 1.

This is our time to honor conserva- tion leaders. This Year’s GGAS mem- ber to receive the award is Mary Jeff- erds. She is an elected member of the East Bay Regional Park District Board of Directors and a representative to the Greenbelt Congress. She has long fought to preserve open space in the Bay Area and is an outstanding ex- ample of the good a committed con- servationist can accomplish.

Harold Gilliam, San Francisco Chronicle environmental columnist and noted author, will receive the award for conservationists is not involved in the Audubon Society. His reports have made the public aware of many threats to the environment from the days of the “Save the Bay” to the California Condor. He is the most re- soected and widely read environment- al writer in our area and certainly de- serves the acclaim of GGAS.

Last year we raised over a thous- and dollars for Audubon Canyon Ranch. Help make this an even great- er success. Join us on June 2.
