Pelagic Birds of Monterey Bay, California WESTERN BIRDS Volume 7, Number 4, 1976 PELAGIC BIRDS OF MONTEREY BAY, CALIFORNIA RICHARD W. STALLCUP, 4409 44th Avenue, Sacramento, California 95824 Monterey Bay is one of the best and most accessiblelocalities in the world to observea large variety of seabirds.At any time of year many speciesof pelagicbirds and mammalsmay be seen. The annualpassing of migrants,the inclusiveperiods of residencyof winteringanimals and their favored haunts on the bay have now been studied adequately enoughthat we may generalizethem in print. In caseswhere descriptionsin popular field guidesare incomplete or inaccurate,a pieceon identificationat seais includedin the follow- ing annotatedlist of selectedbird species. THE BAY Monterey Bay is ideal for pelagicbird trips for severaloutstanding reasons: 1) The edge of the continentalshelf is very closeto shoreat this point, bringingdeep-water species in and cuttingdown boat com- muting time to truly oceanicwaters. 2) The Monterey SubmarineCanyon, the main underwatergeograph- ical feature, is very deep and upwellingscaused by strongnorth- west winds at both rims are attractive to seabirds,particularly storm-petrels. , 3) The bay itself is half-moonshaped and relativelysheltered. 4) The bay is situated far enoughsouth to appeal to warm water speciesand far enoughnorth to appealto cold water species. 5) The weather is stable enoughto allow year-roundtrips. Though the water may be quite rough at times, we have never witnessed a trip on a largerboat canceledfor that reason. ACCESS There are many boatsfor charterfrom Fisherman'sWharf in Monter- ey and a few at Santa Cruz and Moss Landing. All are relativelysmall (fewer than 50 passengers)and none have galleys. WesternField Orni- thologists,many local Audubon chapters and other nature oriented WesternBirds 7:113-136, 1976 113 MONTEREY PELAGICS groupsschedule regular trips which are advertisedin their newsletters and journals. The averagecost is between 12 and 15 dollarsand, at that, still a bargain. Becausethe trips are very popularthey are filled on a first come,first servedbasis and mostalso have waiting lists. Often duringthe tourist seasonand on weekendsshort, inexpensive ($3-5) sight-seeingor whale-watchingtours are run from Fisherman's Wharf, Monterey. Checkthe charteroffices near the end of the pier for schedules. No reservationsare necessary. These trips can be very productivefor birders. Bring food, drinks and warm and waterproof clothes. Afternoons may be warm, so be adaptable. SEASONS Autumn (early Augustto mid-November)is by far the best for num- bers and variety of seabirds. During this time, at least in the last five years, there have been five or more birdingboat trips per year, vastly more than at any other season.Consequently most of our information refers to fall. Winter is very good for seeinglarge numbersof alcids, Black-legged Kittiwakes and Northern Fulmars and is perhapsthe best seasonfor Fork-tailed Storm-Petrel and Short-tailed Shearwater. Springis good for variety (though alwaysless than fall) and for see- ing the birdsin high plumage. Summer is poorly known but is the best seasonto seelarge numbers of Black-footed Albatrosses. AUTUMN TRIPS The best way to proceed (and we have tried many) is to leaveMon- terey harbor as early as the boat operatorswill go (0800 or 0900) and parallelthe PacificGrove shore (checking for Thick-billedMurres among the Commonsand looking at terns, grebes,scoters, Sea Otters and sea lions) until reachingPoint Pinos. Often by this time the skipper will have heard from fishing boats that "the birds" are slightly south and you may wishto detourbriefly toward Carmel Bay. If not, go straight out 5-15 km or more, then cut north toward Santa Cruz to the Monter- ey SubmarineCanyon. Turn east (toward the large concrete smoke stacksat Moss Landing) alongthe canyon'ssouth or north rim, looking for raftingstorm-petrels. Then, as time permits,meander back south in the bay to the harbor. By goingthis way the boat will neverbe heading directlyinto the suln,you are in the heaviestbird concentrationsearly and later the storm-petrelstend to raft in largernumbers. Always devi- ate from courseto head for feedingflocks and do not be too anxious to get far offshoreas birding is often very bleak there. When approach- ing birds on the water, get the skipperto maneuverthe boat so that it 114 MONTEREY PELAGICS is between the sun and the bird for good lightingand so that the boat is broadsideto the bird to allow everyonea goodview. The tendencyis to headstraight for the animaland then only those on the bowcan see it. SPECIES ACCOUNTS PROCE LLA RI FORMES LAYSAN ALBATROSS, Diomedea immutabilis. There are at least five records for the Monterey Bay area, all between 29 November and 27 May. All are recent. Field identification: The bird is mostly white below, has entirely dark gray- brown upper surface of wings and back and has a yellowish-pink bill and pink legs and feet. The white rump is set off by dark rectrices. Laysan is the same bulk as Black-footed Albatross and averagesslightly larger in wingspread. BLACK-FOOTED ALBATROSS, D. nigripes. Numbers vary year to year de- pending upon water temperature and thus, food availability. Chances of seeing one or more near the continental shelf or above the Monterey SubmarineCanyon are very good from May to mid-September and marginal at other times. Large numbershave been found consistentlyin June and July and over 100 individuals have been found together on more than one occasion, usually at active fishing trawlers. Field identification: Mostly uniform dark brown with some white in primary shafts, on the feathers at the base of the bill, and on under and sometimesupper tail coverts. Very old birds may become extremely pale on the belly and under- wings. Bill, legs and feet are always black. Immature Short-tailed Albatrosshas a pale bill, legsand feet and is more uniform brown.

Formerly very common near shore in central California. Now nearly extinct due to destruction of breeding coloniesin the Bonin Islands,600 km southof Japan. It waslast seenin California waters in February 1946. Becausethe speciesis now a Japanesenational monu- ment, is rigidly protected and slowly increasingand becauseMonterey Bay is well within the species'traditional range, it seemslikely that somedayit will be seen here again. Field identification: Adults are similar to the LaysanAlbatross but have white backs and may be washedwith buff. Immaturesare all uniform dark chocolate brown, but have pink bills, legsand feet. Short-tailedsare distinctly larger than our other two albatrossspecies. KEY TO THE REGULAR SHEARWATERS I. If belly white seeA II. If belly dark see B A. 1.

  • New Species Accepted –––––––––––––––––––––––––––––––––––––––––––––––––––––– Swinhoe’S Storm-Petrel (Oceanodroma Monorhis )
    his is the 20th published report of the ABA Checklist Committee (hereafter, TCLC), covering the period July 2008– July 2009. There were no changes to commit - tee membership since our previous report (Pranty et al. 2008). Kevin Zimmer has been elected to serve his second term (to expire at the end of 2012), and Bill Pranty has been reelected to serve as Chair for a fourth year. During the preceding 13 months, the CLC final - ized votes on five species. Four species were accepted and added to the ABA Checklist , while one species was removed. The number of accepted species on the ABA Checklist is increased to 960. In January 2009, the seventh edition of the ABA Checklist (Pranty et al. 2009) was published. Each species is numbered from 1 (Black-bellied Whistling-Duck) to 957 (Eurasian Tree Sparrow); ancillary numbers will be inserted for all new species, and these numbers will be included in our annual reports. Production of the seventh edi - tion of the ABA Checklist occupied much of Pranty’s and Dunn’s time during the period, and this com - mitment helps to explain the relative paucity of votes during 2008–2009 compared to our other recent an - nual reports. New Species Accepted –––––––––––––––––––––––––––––––––––––––––––––––––––––– Swinhoe’s Storm-Petrel (Oceanodroma monorhis ). ABA CLC Record #2009-02.

  • Geographic Variation in Leach's Storm-Petrel
    GEOGRAPHIC VARIATION IN LEACH'S STORM-PETREL DAVID G. AINLEY Point Reyes Bird Observatory, 4990 State Route 1, Stinson Beach, California 94970 USA ABSTRACT.-•A total of 678 specimens of Leach's Storm-Petrels (Oceanodroma leucorhoa) from known nestinglocalities was examined, and 514 were measured. Rump color, classifiedon a scale of 1-11 by comparison with a seriesof reference specimens,varied geographicallybut was found to be a poor character on which to base taxonomic definitions. Significant differences in five size charactersindicated that the presentlyaccepted, but rather confusing,taxonomy should be altered: (1) O. l. beali, O. l. willetti, and O. l. chapmani should be merged into O. l. leucorhoa;(2) O. l. socorroensisshould refer only to the summer breeding population on Guadalupe Island; and (3) the winter breeding Guadalupe population should be recognizedas a "new" subspecies,based on physiological,morphological, and vocal characters,with the proposedname O. l. cheimomnestes. The clinal and continuoussize variation in this speciesis related to oceanographicclimate, length of migration, mobility during the nesting season,and distancesbetween nesting islands. Why oceanitidsfrequenting nearshore waters during nestingare darker rumped than thoseoffshore remains an unanswered question, as does the more basic question of why rump color varies geographicallyin this species.Received 15 November 1979, accepted5 July 1980. DURING field studies of Leach's Storm-Petrels (Oceanodroma leucorhoa) nesting on Southeast Farallon Island, California in 1972 and 1973 (see Ainley et al. 1974, Ainley et al. 1976), several birds were captured that had dark or almost completely dark rumps.

    Summary of 2010 Marbled Murrelet Monitoring Surveys In the Santa Cruz Mountains Prepared For: Department of Parks and Recreation Santa Cruz District 303 Big Trees Park Road Felton CA, 95018 Prepared By: Brian Shaw Klamath Wildlife Resources 1760 Kenyon Drive Redding, CA 96001 12/31/2010 Edited for clarity, organization and content by: Portia Halbert ES for California State Parks 12/19/2014 INTRODUCTION This report covers the results of Marbled Murrelet (Brachyramphus marmoratus) monitoring surveys completed in 2010 for the Santa Cruz District of California State Parks, and is the first of a three-year monitoring effort for the seabird. The surveys took place at Big Basin Redwoods State Park, Portola Redwoods State Park, Butano State Park and San Mateo County Memorial Park. These surveys are carried out in support of and to follow-up data gathered by previous similar studies completed in the Santa Cruz Mountains from years back as far as 1992. It also continues an ongoing effort to study murrelet populations after the Command oil spill that occurred in 1988. METHODOLOGY In previous years, California Department of Fish and Game (DFG) has funded this work; at Portola and Big Basin since 1992 and 1995. At Portola, monitoring years included 1992- 1995, 1998, as well as in 2001-2003 and included only one murrelet observation station. The study has been carried out at Big Basin at five survey stations over the years of 1995-1996, 1998, and 2001-2003. During the 1995-1996, and 1998 the monitoring at Big Basin consisted of five surveys at each station during the protocol period.

  • Conference Highlights, Bird List and Photos
    Highlights of the 2013 WFO Conference in Petaluma, California WFO’s 2013 Conference was one of our most successful meetings ever. We set a new WFO record with over 270 registrants. Science Sessions included descriptions of a new species of seabird, Bryan's Shearwater. Ed Harper’s photo ID quizzes tested our skills with visual challenges and Nathan Pieplow enlightened us with his creative and educational arrangements of bird sounds. The headquarters of PRBO Conservation Science gave us the ideal venue for our opening reception where we enjoyed seeing some of the latest work of artists Sophie Webb and Keith Hansen. We offered six workshops covering a variety of field skills. Thirty-eight field trips, including four pelagic trips, produced a list 240 species. Details below… WFO 2013 Petaluma Science Sessions The Science Sessions kicked off with Peter Pyle presenting on the discovery and identification of a new seabird species, Bryan's Shearwater. Thanks to the efforts of Debbie Vandooremolen and Dave Quady, the session offered a wide variety of presentations including papers on west coast occurrence and identification of "Vega" gull and Common Eider, numerous papers on status and conservation issues involving shorebirds, raptors, Black-backed Woodpecker, Gray Vireo, Tricolored Blackbird, Black Rail, Bendire's Thrasher, grassland birds of the southwest, and more. Other presentations covered use of "citizen science" data including eBird data and Breeding Bird Atlas results. Russ Bradley's Keynote talk gave us all a good overview of the great work being conducted by PRBO Conservation Science on the Farallon Islands and revealed some fascinating data about changes in the ocean ecosystem affecting breeding seabirds.

    RESPONSES TO HIGH TEMPERATURE IN NESTLING DOUBLE-CRESTED AND PELAGIC CORMORANTS ROBERT C. L^$IEWSKI AND GREGORY K. SNYDER ADULTand nestlingcormorants are often subjectto overheatingfrom insolationat the nest. Their generallydark plumage,exposed nest sites, and reradiation from surroundingrocks aggravate the thermal stress. Young nestlingsmust be shieldedfrom the sun by their parents. Older nestlingsand adults compensatefor heat gain throughbehavioral adjust- mentsand modulationof evaporativecooling by pantingand gular flutter- ing. This study was undertakento examinesome of the responsesto high temperaturein nestlingsof two speciesof cormorants,the Double-crested Cormorant,Phalacrocorax auritus, and the PelagicCormorant, P. pelagicus. The evaporative cooling responsesin birds have been studied in some detail in recent years (see Bartholomewet al., 1962; Lasiewski et al., 1966; Bartholomewet al., 1968; Calder and Schmidt-Nielsen,1968, for more detailed discussions),although much still remains to be learned. MATERIALS AND •VIETI-IODS The nestling cormorantsused in this study (four Phalacrocoraxpelagicus and four P. auritus) were captured from nests on rocky islands off the northwest coast of Washington. As their dates of hatchingwere not known it was impossibleto provide exact ages. From comparisonsof feather developmentwith descriptionsin the literature (Bent, 1922; Palmer, 1962), we judged that the pe'lagicuschicks were approximately 5, 5, 6, and 6 weeksold, while'the auritus chickswere 3.5, 3.5, 4.5, and 6 weeksof age upon capture. The nestlingswere taken to the laboratoriesat Friday Harbor, Washington on the day of capture and housed in three 4' X 4' X 4' chicken wire cages. The cageswere equippedwith plywood platforms for the birds to sit on and coveredon top and two sides to shield birds from wind and rain.

  • Common Birds of the Estero Bay Area
    Common Birds of the Estero Bay Area Jeremy Beaulieu Lisa Andreano Michael Walgren Introduction The following is a guide to the common birds of the Estero Bay Area. Brief descriptions are provided as well as active months and status listings. Photos are primarily courtesy of Greg Smith. Species are arranged by family according to the Sibley Guide to Birds (2000). Gaviidae Red-throated Loon Gavia stellata Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: A small loon seldom seen far from salt water. In the non-breeding season they have a grey face and red throat. They have a long slender dark bill and white speckling on their dark back. Information: These birds are winter residents to the Central Coast. Wintering Red- throated Loons can gather in large numbers in Morro Bay if food is abundant. They are common on salt water of all depths but frequently forage in shallow bays and estuaries rather than far out at sea. Because their legs are located so far back, loons have difficulty walking on land and are rarely found far from water. Most loons must paddle furiously across the surface of the water before becoming airborne, but these small loons can practically spring directly into the air from land, a useful ability on its artic tundra breeding grounds. Pacific Loon Gavia pacifica Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: The Pacific Loon has a shorter neck than the Red-throated Loon. The bill is very straight and the head is very smoothly rounded.

The form that occurs in the NACC area is nominate pacificus, so the current species account would remain unchanged except for the distributional statement and notes. Background: The Fork-tailed Swift Apus pacificus was until recently (e.g., Chantler 1999, 2000) considered to consist of four subspecies: pacificus, kanoi, cooki, and leuconyx. Nominate pacificus is highly migratory, breeding from Siberia south to northern China and Japan, and wintering in Australia, Indonesia, and Malaysia. The other subspecies are either residents or short distance migrants: kanoi, which breeds from Taiwan west to SE Tibet and appears to winter as far south as southeast Asia.
