PACIFIC SEABIRDS A Publication of the Pacific Seabird Group Volume 34 Number 1 Spring 2007 PACIFIC SEABIRD GROUP Dedicated to the Study and Conservation of Pacific Seabirds and Their Environment The Pacific Seabird Group (PSG) was formed in 1972 due to the need for better communication among Pacific seabird researchers. PSG provides a forum for the research activities of its members, promotes the conservation of seabirds, and informs members and the public of issues relating to Pacific Ocean seabirds and their environment. PSG holds annual meetings at which scientific papers and symposia are presented. The group’s journals are Pacific Seabirds (formerly the PSG Bulletin), and Marine Ornithology (published jointly with the African Seabird Group, Australasian Seabird Group, Dutch Seabird Group, and The Seabird Group [United King- dom]; www.marineornithology.org). Other publications include symposium volumes and technical reports. Conservation concerns include seabird/fisheries interactions, monitoring of seabird populations, seabird restoration following oil spills, establishment of seabird sanctuaries, and endangered species. Policy statements are issued on conservation issues of critical importance. PSG mem- bers include scientists, conservation professionals, and members of the public from both sides of the Pacific Ocean. It is hoped that seabird enthusiasts in other parts of the world also will join and participate in PSG. PSG is a member of the International Union for Conservation of Nature (lUCN), the Ornithological Council, and. the American Bird Conservancy. Annual dues for membership are $25 (individual and family); $15 (student, undergraduate and graduate); and $750 (Life Membership, payable in five $150 install- ments). Dues are payable to the Treasurer; see Membership/Order Form next to inside back cover for details and application.

This pioneering federal marine program is now being integrated with the sanctuary Ecosystem Assessment Surveys (SEAS), which provide valuable ecosystem data on the marine environment to assist sanctuary management in resource protection. Shoreline surveys create a baseline data set that can be used to detect species mortality events and the effects of environmental factors such as oil spills. Dead and live bird and marine mammal counts can establish spatial and temporal trends and the interrelationships between beached and live species abundance. The use of volunteers in long-term monitoring is hnancially benehcial and, more importantly, allows the public to take an active role in environmental protection, thereby increasing awareness and the capacity for stewardship. INTRODUCTION Beach Watch is a long-term monitor- ing program of the Gulf of the Farallones National Marine Sanctuary (GFNMS), implemented by the Farallones Marine Sanctuary Association. The program was initiated in 1993 as a response to the threat of oil spills in the sanctuary. The goals of the Beach Watch program are to provide a baseline data set on the presence of live and beach-cast marine organisms; assist sanctuary management in the early detection of natural and human-caused environmental events; develop a network of volunteer expert surveyors who can respond during an oil spill; and educate the public about the coastal environment and how they can make a difference in protecting their beaches. Beach Watch is now part of the Sanctuary Ecosystem Assessment Sur- veys (SEAS), a suite of monitoring programs in the GENMS. Other efforts in SEAS include monitoring of the shoreline, intertidal, and pelagic habi- tats, and collecting environmental data on physical oceanography as correlated with marine vertebrate and invertebrate abundance. Together, these assessments are designed to provide an overview of ecosystem health and status to sanctu- ary management to assist in resource protection. The goal of SEAS is to link all of the monitoring data collected by the sanctuary and provide biological observational data and habitat charac- terization for the Gulf of the Earallones and Bodega regions. METHODS Currently, Beach Watch volunteers survey 42 beach segments every two to four weeks on the central California coast. The Beach Watch area includes the Gulf of the Earallones and Monterey Bay National Marine Sanctuaries, be- tween Bodega Head in Sonoma County and Ano Nuevo State Reserve on the San Mateo/Santa Cruz County line (Eigure 1). Erom September 1993 through Sep- tember 2004, 6419 surveys were com- pleted, monitoring 14,405 km of coast- line. In 2004, ninety-two volunteers conducted 771 surveys of 1,657 km of shoreline. To compare data among dif- ferent parts of the coastline, numbers of dead and live vertebrates are quantified as encounter rates (i.e. number of birds per kilometer surveyed). The Beach Watch volunteers attend 80 hours of classroom and fieldwork training. Surveys are conducted by teams of one to four surveyors. Along each beach segment, live birds and marine mammals are censused, dead vertebrates are documented, human and dog activity is recorded, and data are collected on oil and tarball presence, wrack, inver- tebrates, and stream and lagoon status (Roletto et al. 2005). Surveyors search the beach in a zigzag pattern, combing through wrack for beached specimens. Data collected on each beached specimen are: species identification, condition (rate of decomposition), sex, age, evidence of scavenging, probable cause of death (when possible), occurrence, extent and location of oil, and (if the specimen is tagged), tag number, color and location. Each dead specimen is photographed for later verification by an ornithologist or a marine mammal expert to confirm spe- cies identification, age, and sex. Surveyors use 7-10 power binocu- lars to identify and count live birds and marine mammals which pass within 90 m landward and seaward of the beach, as well as marine mammals that can be identified beyond 90 m. Animals that cannot be identified to species are recorded to the nearest positively identifi- able taxonomic grouping. BENEFITS Coastal surveys of live and dead birds and marine mammals are benefi- cial to sanctuary management. Consis- tently gathered beached vertebrate data from the shoreline of the sanctuary pro- vide baseline species mortality rates for a large geographical area. Standardized beach surveys can detect oil and tarball events. Unusual mortality events can be detected, pinpointed, and their magni- tude evaluated. Live bird and mammal counts reveal changes in beach usage over time. Live and dead vertebrate data can be compared to reveal trends and patterns. Beach Watch surveys have been used Pacific Seabirds • Volume 34, Number 1 • Spring 2007 • Page 2 ARTICLE - Beach Watch surveys Figure 1 . Map of locations of beach segments monitored by Beach Watch. to discover oil and tarball events, assess their damage, and contribute data for the selection and scaling of restoration proj- ects. Regular baseline data of beached birds can provide historic mortality rates and known species composition which can be compared to the species beached during oil spills. Oil spills and tarball events can be clearly demarcated because of the low background level of beached oiled birds in the sanctuary (Roletto et al. 2003). Surveyors are trained in oil and tarball documentation, which allows them to respond quickly during an oil spill event. Standardized beached bird sur- veys reveal patterns of bird mortality in coastal areas (Page et al. 1982). For example, in the winter of 2003-2004, an unusual number of Northern Fulmars {Fulmarus glacialis) were found beached from Oregon down to Southern Califor- nia (Harvey et al. 2004). This pattern of deposition rates reflected a winter irrup- tion of fulmars through the central and northern California region (Harvey et al. 2004, NOAA 2003). Annually, Beach Watch data show a slight to moderate increase in mortality from November through March as Northern Fulmars migrate to the Gulf of the Farallones to feed. In November 2003, the dead fulmar encounter rate peaked at 5.04 fulmars encountered per km (Figure 2), a fourfold increase over any previous year. The sud- den die-off in Northern Fulmars, as seen in higher numbers of beached fulmars, occurred at the same time as high counts of live fulmars at sea (Harvey et al. 2004, R. Stallcup pers. comm. 2004), perhaps indicating lack of food in the Gulf of Alaska and a displacement of the popula- tion to offshore California waters. A similar link between rates of beached bird deposition and encounter rates of live birds was observed at Francis Beach, designated Beach 4-05, a survey segment in Half Moon Bay State Park in San Mateo County (Figure 1). Beginning in January 2003, surveyors documented higher than normal numbers of dead gulls. This elevated mortality rate lasted through April 2003 and occurred again in the winter and spring months of 2004. The mean monthly encounter rate of dead gulls during the mortality event peaked during the month of March at 0.34 gulls encountered per km, compared to previ- ous years (1996-2002), in which the monthly mean encounter rate in March was 0.01 gulls per km (Figure 3). During the 2003-2004 mortality events on Francis Beach, the majority of the beached gulls found in the peak die-off months of January-April were Glaucous-winged Gulls {Lams glauce- scens) (Figure 4). The average March encounter rate of dead Glaucous-winged Gulls for the two years was 0.21 birds per km (65.5% of all dead gulls encoun- tered), compared with Western Gulls {Lams occidentalis) at 0.08 birds per km (24.5% of all dead gulls encountered) (Figure 4). The species composition of dead gulls changed seasonally (Figure 4). Glaucous- winged Gulls migrate out of the Gulf of the Farallones during the upwelling season (NOAA 2003), and in September and October there is an annual die-off of recently fledged Western Gulls in central California (Page et al. 1982). The peak in counts of all dead gull species on Francis Beach mirrors live counts seasonally and annually. This beach has historically been a roosting site for large numbers of gulls in the winter, with a maximum mean encounter rate of 26.3 live gulls per km during Janu- ary in 1996-2004. The presence of the convergence of two fresh water streams and a nearby landfill may attract gulls to this beach.
