Machias Seal Island Seabird Research and Monitoring on Machias Seal Island RESEARCH PROTOCOLS Atlantic Laboratory of Avian Research University of New Brunswick Fredericton, N.B. Canada Edited by A.W. Diamond April 2013 1 Preface The Atlantic Laboratory of Avian Research (ALAR – then known as ACWERN), at the University of New Brunswick (UNB) began a long-term seabird monitoring and research program on Machias Seal Island (MSI), New Brunswick, in the spring of 1995. Initially, as part of the research for K.D. Amey’s M.Sc. at UNB (Amey 1998), field methods were employed that were acquired from a variety of sources, such as previous work experience on other seabird projects, personal communications with seabird authorities, colleagues in the Gulf of Maine Seabird Working Group (GOMSWG) and the literature. These methods have been refined subsequently to increase efficiency and minimize disturbance to the birds (Paquet and Diamond, 1998b). For the sake of year-to- year comparisons, it is important that a long-term monitoring program use the same methods each year (Diamond 1997). Therefore the primary purpose of this document is to provide details of the methods which have been developed for this specific field site and its seabirds. This document provides the research protocols that will be followed while collecting data on MSI. The protocols are subdivided according to species. This document also includes additional sections which deal with collecting environmental data and other research activities. Large sections of this document were incorporated from previous versions of the MSI protocol and future versions will likely draw heavily on this one. Although not listed here, numerous individuals have contributed over the years to establishing appropriate guidelines for the research on MSI and have spent many hours documenting proper methods. Their hard work is greatly appreciated. The current version is particularly indebted to extensive revisions by Travis Clarke, Kirsten Bowser, Kevin Kelly, and Lauren Scopel. 2 Table of Contents TABLE OF CONTENTS

  • Razorbill: Species Information for Marine Special Protection Area Consultations
    Natural England Technical Information Note TIN124 Razorbill: species information for marine Special Protection Area consultations The UK government has committed to identifying a network of Special Protection Areas (SPAs) in the marine environment by 2015. Natural England is responsible for recommending potential SPAs in English waters to Defra for classification. This and other related information notes have been written to provide further information to coastal and marine stakeholders about the bird species we are seeking to protect through Marine SPAs. For more information about the process for establishing marine SPAs see TIN120 Establishing Marine Special Protection Areas. Background The Birds Directive (EC Directive on the conservation of wild birds (79/409/EEC)) requires member states to identify SPAs for: rare or vulnerable bird species (as listed in Annex I of the Directive); and regularly occurring migratory bird species. Razorbills Alca torda are a regularly occurring migratory bird species in Europe. They are 37– 39 cm long with a wingspan of 63-68 cm1. Their typical lifespan is 13 years and the oldest Razorbill by Andy Brown reported individual was over 41 years old2. The majority of UK birds nest in the north and west of Scotland. In England, razorbills breed on Conservation Status coasts and islands in the north and south-west. UK amber-listed bird of conservation concern3. The largest English colony is at Flamborough Distribution and population Head and Bempton Cliffs in Yorkshire. Razorbills only breed along North Atlantic coasts, including the UK. Migration/movements Adults and dependent young disperse offshore The Seabird 2000 census lists the UK breeding from colonies in July – August, with adults population at 187,100 individuals, 20% of global becoming flightless during this period due to 4 population with 11,144 individuals breeding in moult.

SUMMARY OF OBJECTIVES, CONCLUSIONS AND IMPLICATIONS WITH REGARD TO OCS OIL AND GAS DEVELOPMENT A. Objectives The objective of RU 460 is to describe important components of the biology of seabirds in northern Alaska, including relationships among seabirds, their supporting food webs and the physical environment. To accomplish this objective we have concentrated on studies of thick-billed murres (Uris lomvia), common murres (U. aazge) and black-legged kittiwakes (Rissa tridactyZa), the most wide-spread, and among the most numerous, of all seabird species in the region. Moreover, murres and kittiwakes are easily studied compared to other species, and are sensitive indicators of environmental change. B: Conclusions Our principal conclusions are that numbers of murres at two major breeding colonies in northern Alaska are declining and that annual vari- ability is high in a variety of elements of murre and kittiwake breeding biology.

  • Razorbill Alca Torda in North Norway
    THE EFFECT OF PHYSICAL AND BIOLOGICAL PARAMETERS ON THE BREEDING SUCCESS OF RAZORBILLS (ALCA TORDA L. 1758) ON MACHIAS SEAL ISLAND, NB IN 2000 AND 2001 by Virgil D.

Diamond, Ph.D., Biology and Forestry & Environmental Management, J.W. Chardine, Ph.D., Canadian Wildlife Service Supervisory Committee: D.J. Hamilton, Ph.D., Mt Allison University Examining Board: This thesis is accepted. ………………………………………… Dean of Graduate Studies THE UNIVERSITY OF NEW BRUNSWICK Fredericton, New Brunswick, Canada December, 2004 ABSTRACT The influence of various physical and biological parameters on the breeding biology of Razorbills (Alca torda) on Machias Seal Island (MSI) was studied in 2000 and 2001. The major predators (gulls) on seabird eggs and chicks on MSI are controlled, providing an unusual opportunity to study breeding biology in the virtual absence of predation. The timing of egg-laying was right skewed in both years. A complete survey 10-14 June 2000 of all Razorbill breeding habitat on MSI was combined with radio telemetry to estimate the total number of inaccessible breeding sites that may not have been counted. A corrected breeding pair estimate for MSI is 592 ± 17 pairs. Overall breeding success was 55% in 2000 and 59% in 2001. Most chicks that hatched also departed the island, so differences in breeding success were due chiefly to differences in hatching success. Adults breeding in burrows were more successful than adults in crevice and open nest sites.

  • Common Murre •.• Thick-Billed Murre
    j. Field Ornithol., 54(3):266-274 THE FLEDGING OF COMMON AND THICK-BILLED MURRES ON MIDDLETON ISLAND, ALASKA BY SCOTT A. HATCH Three speciesof alcids,Common and Thick-billed murres (Uria aalge and U. lornvia)and the Razorbill (Alca torda),have post-hatchingdevel- opmental patterns intermediate to precocialand semi-precocialmodes (Sealy1973). The youngleave their cliff nestsites at aboutone quarter of adult weight and completetheir growth at sea.At departure, an event here looselyreferred to as "fledging," neither primary nor secondary flight feathersare grown, but well-developedwing covertsenable lim- ited, descendingflight. The adaptivesignificance of thispattern maybe that leadingthe young to distantfeeding areasis more efficientthan lengthy foraging flights by adultsonce the chicks'energetic requirements exceed some critical level (Sealy 1973, Birkhead 1977). The risk to predation is probably greater in exposednest sitesthan at sea, contributing further to the selectiveadvantage of earlyfledging (Cody 1971, Birkhead1977). Given these constraints,however, larger chickswould be expected to better survivethe rigorsof fledging,increased activity at sea,and the vagaries of weather. Hedgren (1981) analyzed278 recoveriesof CommonMurres banded as fledglingsand found no significantrelationship between fledging weight and subsequentsurvival. This result is paradoxicalin view of a strong expectationto the contrary and evidencethat such an effect occursin other speciesof birds (Perrins 1965, Perrinset al. 1973, O'Con- ner 1976). Hedgren suggestedthe nestlingperiod of murres,averaging about3 weeks,is determinednot by a thresholdin bodysize, but by the relativelyconstant time requiredto completefeather growth.Birkhead (1977) alsoemphasized the need for chicksto attain a critical weight: wing-arearatio prior to fledging. Clearly, however,body weight and feather developmentare not mutuallyexclusive factors affecting fledg- ling survival.

  • Alcid Identification in Massachusetts
    ALCID IDENTIFICATION IN MASSACHUSETTS by Richard R. Veit, Tuckernuck The alcldae, a northern circvimpolar family of sesbirds, are memhers of the order Charadrilformes and thus most closely related to the gulls, skuas, and shorehirds. All alcids have approximately elliptical bodies and much reduced appendages, adaptations for insulation as well as a streamlined trajectory under water. Their narrow flipperlike wings are modified to reduce drag durlng underwater propulsión, and are, therefore, comparatively inefficient for flight. Razorbills, murres, and puffins feed predominately on fish, such as the sand launce, capelin, Arctic cod, herring, and mackerel. The Dovekie, by far the smallest Atlantic alcid, eats zooplankton exclusively, such as the superabundant "krill." The Black Guillemot, unique.in its con- finement to the shallow littoral zone, feeds largely on rock eels or gunnel. As with many pelagic birds, the alcids' dependence on abundant marine food restricts them to the productive vaters of the high latitudes. Bio- logical productivity of the oceans increases markedly towards the poles, largely because the low surface temperaturas there maintain convection currents which serve to raise large quantities of dissolved mineral nu­ triente to the siirface. The resultant high concentration of nutriente near the surface of polar seas supports enormous populations of plankton and, ultimately, the fish upon which the largar alcids feed. Alcids are comparatively weak flyers and are not regularly migratory, but rather disperse from their breeding ranga only when forced to do so by freezing waters or food scarcity. Massachusetts lies at the periphery of the ranges of these birds, with the exception of the Razorbill. It i& only under exceptional circumstances, such as southward irruptions coupled with strong northeasterly storms that substantial numbers of alcids are observad along the Massachusetts coastline.
