ASILOMAR BOAT TRIP Participants at the recent Western Regional Conference in Asilomar took enough time off to board five boats out of Monterey for a day of pel- agic birding. Highlights of the trip included as many as five Black-footed Albatross, Cassin’s Aukelets, Rhinoceros Aukelets in breeding plumage, Sooty Shearwaters, a few Pink-footed Shearwaters, and a few late Puhnars. Observers also saw a number of gray whales and sea otters, but did not see any porpoise during the trip. The absence of these fine animals caused some concern about their present status.— VAEERIA DACOSTA. FIELD TRIP REPORTS Some 35 people enjoyed clear weather in the San Joaquin Valley on January 29 and 30. Highlights at the Los Banos State refuge were close views and sounds of many White-faced Ibis and Long-billed Curlews. At the federal refuges, San Luis and Merced, we saw Sandhill Cranes, thous- ands of Snow and Canada ( Cackling ) Geese, many Shovelers and Cinnamon Teal. We also saw Burrowing Owls and two Rough-legged Hawks. Leader, Marie Mans. On March 5, 63 people enjoyed a fine day of birding along the Drake’s Estero Trail, where there is a considerable variety of habitat— lagoons, lakes, mudflats, green hillsides and the estero itself. Thirty-five species were seen, including an Osprey, several hundred Black Brant, Say s Phoebe, Green-winged Teal, and the Harris Sparrow that has been seen by many observers this winter. Leader, Aileen Pierson. Despite an overcast morning, about fifty people turned out for a walk around Tubbs Island on March 12. Along the road leading to the island. - 39 - 1972 THE GULL May Ring-necked Pheasants were abundant, and many people enjoyed their best looks at these colorful introduced game birds. About 40 species were seen, including White-tailed Kites, a Golden Eagle, a huge flock of Long- billed Cm-lews, and a Burrowing Owl. Leader: S.S. Whitehead. On March 28, about 25 birders met at Doran Park for a trip around Bodega Bay and to Bodega Head. The weather was clear, but very windy. About 60 species were sighted, including all three Loons, Pelagic Cormor- ants in breeding phunage. Black Brant, Osprey, and many other shore and water birds. Leader: Jim Clayton. COVEL'S CONSERVATION CORNER We returned from the Western Regional Conference in Asilomar brimming witli a heady mixture of inspirational themes, reports of signifi- cant progi'ess here and there in conservation, and traumatic accounts of devastating assaults on our environment and ^vildlife. Introduction of bighorn sheep to the Lava Beds National Monument- part of their ancestral range— was announced as a joint venture of the Cali- fornia Department of Fish and Game and the U.S. Bureau of Sport Fish- eries and Wildlife. When we asked regional Bureau chief John Findlay about the timetable for introducing tule elk to the San Luis Refuge in the San Joaquin Valley, however, we learned that this possibility is “still under study.” Other potential elk habitats in California are also being smrveyed. We heard with horror and dismay of the 4,000 lethal oil sumps that remain in the San Joaquin Valley. Phil Schaeffer, interne-aide to Paul Howard in the Sacramento office of the National Audubon Society, has investigated and photographed these sumps and estimates that 35,000 game birds armually meet their doom in them. He said that perhaps twice that number of non-game birds and small animals die as a result of these sumps. The oil industry now is phasing them out, and Assembly Bill 1561 would outiaw them permanently. We learned of the rapid destruction of the California desert by off- road veliicles from slides taken by the Bureau of Land Management and from a dramatic film. The Wyoming eagle-kill scandal was touched off by curious high school boys who reported carcasses to the Murie Audubon Society. The all-out search, detective work, and alerting of government agencies that followed would make a best-seller. These discoveries probably led to the President’s recent ban on using poisons for predator control on public lands, lands. Do we need a Southern Crossing? Can the environment withstand a Southern Crossing? Voters in six Bay Area counties will give their answer to such questions on June 6th when they vote on Proposition A, which reads: “Shall the California Toll Bridge Authority be premitted to con- struct the Southern Crossing Bridge? Yes No ” Most local govern- ments and legislators, virtually all local environmental organizations, and the National Audubon Society have taken positions against the measure. •40- 1972 THE GULL May The Southern Crossing Bridge gradually might be accepted on our horizon were it not for the serious tlireats it would present to the environ- ment. What of the emissions an estimated 61,000 vehicles daily by 1980 would release into the atmosphere? What about tire miles of new freeways the traffic from this eight-lane crossing would require to be built on bay shore fill? What about the economic effect of the bridge on B.A.R.T.? Vlany people believe B.A.R.T. should be extended, yet if the tolls on existing bridges must be raised for twenty-five years to pay for the South- ern Crossing where will the money be found to extend B.A.R.T.’s services? The new Metropolitan Transportation Commission is trying to develop a modern, regional transportation system that might offer saner and safer alteniatives to more bridges and freeways. Let’s give them a chance. —PAUL COVEL, Conservation Chairman. DOCENTS NEEDED AT OAKLAND MUSEUM Additional docents are needed to serve as volunteer interpretive guides in the Natural Sciences Gallery at The Oakland Museum. The next train- ing program to prepare volunteers to serve as docents will begin in Sep- tember, 1972. Prospective docents are required to take a two-semester course on general and California ecology and complete one semester of in-gallery training within the Museum, which includes familiarization with the natural science exhibits and training in public speaking and communi- cation. A fee of $45 is charged for the third semester. A limited number of scholarslrips are available for anyone who might not be able to complete the third semester because of the charge. After completion of the three-semester training program, docents are required to serve as interpretive guides approximately two half-days a month. Active docents are eligible to participate in a continuing education program consisting of lectures, discussions and field trips that continue to expand the docents’ knowledge of California ecology. Persons interested in participating in the docent program or receiving additional information should call the Docent Coordinator at The Oakland Museum at 893-0340 or 273-3515. NEW BILL PROCEDURE To expedite the payment of chapter bills, we are asking that they be submitted to the office manager, Chris Carroll, at the GCAS Center ( 1749 Grove St., Berkeley, Calif. ) by the 20th of each month. He will then pro- cess and forward all bills to the treasurer for payment by the first of each month. We hope this new system will be a more practical way of reimburse- ment and urge that biUs be submitted by the 20th of the month so that payment can be made promptly. CAMPAIGN TO SAVE SONOMA COAST The Sonoma Coast State Park Committee is appealing to all nature lovers and conservationists to help it save important tracts of land along California’s beautiful Sonoma coastline. Of prime importance are North -41 THE GULL May 1972 Jenner Beach at the moutli of the Russian River and Penny Island, a 29- acre island in the estuary of the Russian River that is a sanctuary for sea and shore birds. These lands are imminently threatened by development and must be saved now if they are to be saved at all. If you would like to make a contribution to this project or if you desire further information, write to the Sonoma Coast State Park Committee, P.O. Box 21, Jenner, California 95450. The committee is a volunteer group organized within the California State Parks Foundation. All contributions are tax deductible.

NEW SERVICE FOR BIRDERS The Golden Gate Audubon Society has recently instituted a Field Observations Bulletin Board at the Audubon Center, 1749 Grove St., Berke- ley, Cahfomia. Established and maintained by Vi Homem and Pete Rose- marin, this board will provide up-to-date information ( revised weekly ) on the rare and uncommon avian visitors that turn up in the Bay Area. Tliis service will allow an increased number of birders to learn about interest- ing birds in the region while such birds are still here. It will also help people plan their local birding expeditions. All unusual observations will be posted except nesting sites and those made on private property. BIRDING CALENDAR May is perhaps the best month for finding land birds in the Bay Area. Most of the species that nest here have ariaved; many migrants bound for other regions may still be seen. For places to go, consult last month’s Gull. A couple of additional suggestions; Pinnacles National Monument (see Field Trips for May) is alive with birds in May, including a few species that are rather uncommon in the Bay Area proper, such as Road- runner, Black-chinned Hummingbird, Lewis’ Woodpecker, House Wren, Canyon Wren, Rock Wren, Blue- gray Gnatcatcher, Phainopepla, and Lawrence’s Goldfinch. A trip to various parks, rivers, and refuges in the Sacramento and San Joaquin Valleys might turn up many of the above species, as well as others such as the Blue Grosbeak and Yellow-billed Cuckoo ( very rare ) . Finally, don’t ignore the shorelines and coastal habitats in the Bay Area this month. You may still see some interesting migrating shorebirds, many of which will be decked out in bright nuptial plumage. CORRECTION; In last month’s “Birding Calendar,” I incorrectly stated that one could see “Indigo Buntings” in Laurel Canyon in Tilden Park. I meant to say “Lazuli Butings.” The Indigo Bunting, of coiu'se, is an eastern species, which I have not seen in Laurel Canyon, or anyv'here else for that matter.— STEVE WHITNEY, Editor. - 43 - 1972 THE GULL May A GULL SPECIAL REPORT-DUCK BOTULISM Last August, Western Duck Sickness killed 400 Mallards at the Lake Merritt Waterfowl Refuge in Oakland, California. At the same time, 5000 birds died from the same disease at the Bear River Migratory Bird Refuge on the north shore of tlie Great Salt Lake. Western Duck Sickness is a form of botulism, the bacterial food poisoning that is also fatal to humans. Botulism results from ingesting a powerful nerve toxin produced by the bacillus, Clostridium botidinum, which exists in both soil and water. Its spores are extremely resistant to phyical changes, but require special conditions for germination. When the spores do begin to multiply, they produce botulism toxin in the process. If ingested by a bird or animal, the toxin enters the blood- stream through tlie digestive tiact and quickly begins to inhibit the ner\^e action that controls breatliing and the movement of legs, arms or wings. Death results from the paralysis of the respiratory muscles. Scientists have identified six types of Clostridium botulinum, all of which are common in the United States. Types A, B, E and F cause botu- lism in humans. Type D is responsible for the disease in other mammals. Type C is the source of Western Duck Sickness. Duck botulism commonly occurs in the brackish lakes and marshes of the Western United States, but outbreaks have also occured in other regions of the country. Alkaline conditions seem necessary for the pro- duction of type C toxin, but only a slight degree of alkalinity may be enough. Type C spores lie dormant in the muddy bottoms of lakes for most of the year. During this period, they can be eaten without ill effects. In late summer, however, when water levels drop and this mud is either exposed entirely or covered by shallow water, the spores may begin to multiply and produce their toxin. Apparently the mud must be fairly warm for this process to occur, for it rarely happens in cool weather or when the mud is covered by deep water. Yet even when conditions seem perfect, outbreaks of duck botulism may be small or non-existent. So far, pathologists studying the disease are unable to explain this irregularity except to say that other, still unknown factors are involved. Surface-feeding ducks like Mallards, Pintails and Shovelers are most likely to ingest tlie botulinus toxin because they dabble in the mud for their food. Otlier birds are also susceptible to the poisoning, but are saved by different feeding habits. In late summer, huge flocks of ducks begin to fly south from then- breeding grounds. On their- way, they stop to feed at various ponds and marshes. Especially large concentrations of waterfowl may visit wetlands in the Great Basin region, where water is scarce. Their arrival often coincides with the germaination of botulinum spores. - 44 - 1972 THE GULL Ma \V ithin 24 hours, most of a once healthy Hock may be near death, witli thousands of birds lying on the mudflats or floating helplessly in shallow ponds. Those not already dead are limp. Their breathing is labored. Their eyes may be clouded and they may show signs of chaiThea. If horse serum anti-toxin is available, most of the tieated birds will survive. Yet many will die before they can be picked up. If the outbreak is large, effective treatment will be impossible, for neither sufficient amounts of anti-toxin nor numbers of men are available for tire job. All that remains in such cases is to pick up the dead birds as rapidly as possible. According to Paul Covel, the Chief Natinalist at Lake Merritt, anti- toxin is now unavailable because no pharmaceutical firm is willing to bear the cost of its production. The market for the anti-toxin is too small and irregular to be profitable. The U.S. Fish and Wildlife Service still has ten liters of anti-toxin, but this supply is reserved for research and for an out- break that might endanger a rare species. In humans, the use of horse serum anti-toxin is risky because of pos- sible serum infection. Nor does it always work in serious cases. Ducks respond better to anti-toxin, but there is disagi'eement as to how much better. Covel said that the anti-toxin was very effective. He cited a 1959 study for tire National Audubon Society that claimed the anti-toxin to be 92% effective in moderate cases of botulism and 65% in severe cases. The study said that only one-third of the afflicted birds could be expected to survive as the result of alternative methods of treatment. This estimate agrees with the recent experience at Lake Merritt, where, without the toxin, only 200 out of 600 ducks were saved. The U.S. Fish and Wildlife Service, however, claims that research at the Bear- River Refuge indicates that 70% of the affected ducks ^^^ll sur- vive without any ti’eatment at all, and that the use of anti-toxin only in- creases this figure by 15% . Covel, who was at Bear River during the recent outbreak, doubts this statement. He said that no attempt was made to treat the sick birds and that so far as he knew, most of tliem died. At the same time, naturalists and volunteers at Lake Merritt saved 200 ducks by forcing an epsom salts solution down their gullets. The solution act as an emetic, flusliing most of the poison from the birds’ sys- tems. Humans stricken with botulism usually receive similar treatment. The recent epidemic at Lake Merritt was finally halted, however, only after the locks connecting the lake to San Francisco Bay were opened to permit the influx of additional water. According to Lionel Kelt, the assistant naturalist at the lake, the number of dead birds picked up each day thereafter dropped off rapidly. Within a week the outbreak was over. Kett attributes this success to the cooling action of the additional water, which covered exposed mud and generally lowered the water - 45 - 1972 THE GULL May temperature of the shallow lake. This process has been used successfully before and remains one of the most effective methods of controlling duck botulism. Some authorities believe that such flooding also may dilute the botulinum toxin to a point where it is no longer dangerous. Not the least important effect of raising the water level is that surface- feeding ducks no longer have access to the toxin-bearing muds. This forces them to seek other food sources. The same result can also be achieved by completely ch-aining a pond so that it is no longer attractive to waterfowl. Both methods have been used at Bear River as preventive measures. Duck botulism remains a serious threat to waterfowl populations using the western flyways. It will not easily be controlled except by keeping water levels high in western lakes and marshes. If the experience of wildlife managers at Bear River is significant, however, this condition is not likely to occur so long as farmers require water for irrigation purposes.— SW. CANYON RANCH NEWS Audubon Canyon Ranch has announced that the drive to match two- to-one the $35,000 grant by the Charles E. Merrill Trust has gone over the top. The money raised will be spent for the acquisition of “significant, undeveloped wild lands,” including additional purchases along the east shore of Tomales Bay. Two recent acquisitions in this area are the entire 120-acre delta of Walker Creek, the largest stream in Marin County, and a strip of land over one mile long betv'een Walker Creek and Highway One just inland from the delta. Together, these acquisitions will preserve as open space the richest and most important area of Tomales Bay from an ecological stand- point. The area will be posted as a wildlife sanctuary. * * » « Helen Pratt is starting the sixth year of her study of the nesting cycle of the herons and egrets in the rookery at Audubon Canyon Ranch. This valuable work grows more significant each year. Since it is impossible, however, for one person to check closely all the visible nests every day from the time the eggs are laid until the day the chicks are fledged, Mrs. Pratt is asking Audubon members to help her keep track of the nests during May. Volunteers please call Helen Pratt at 388-1966.
