Canadian Field-naturalist 128(1): 7 2–76. reported values for eggshell thickness in Common Murre ( Uria aalge ) are few, and even fewer since the decline in use of organochlorine pesticides and other environmental pollutants that caused significant thinning of shells. The eggshells of Common Murres and Thick-billed Murres ( Uria lomvia ) are among the thickest and heaviest, proportionately, of any bird and this represents a non-trivial maternal investment. We measured the length and breadth of Common Murre eggs collected from Machias Seal island, new Brunswick, in 2006, and Gull island, newfoundland and labrador, in 2012, and we measured the thickness of the eggshells. Shell thickness was not related to egg size or volume, and it varied in individual eggs. The shells of Common Murre eggs from Machias Seal island (mean and standard deviation [SD] (0.767, SD 0.078 mm) and Gull island (0.753, SD 0.057 mm ) were significantly thicker than any previously reported value and among the thickest of all birds . Such thickness is likely a result of nesting on rock substrate with no nesting material and, perhaps, high breeding densities. -
A Review of the Fossil Seabirds from the Tertiary of the North Pacific
Paleobiology,18(4), 1992, pp. 401-424 A review of the fossil seabirds fromthe Tertiaryof the North Pacific: plate tectonics,paleoceanography, and faunal change Kenneth I. Warheit Abstract.-Ecologists attempt to explain species diversitywithin Recent seabird communities in termsof Recent oceanographic and ecological phenomena. However, many of the principal ocean- ographic processes that are thoughtto structureRecent seabird systemsare functionsof geological processes operating at many temporal and spatial scales. For example, major oceanic currents,such as the North Pacific Gyre, are functionsof the relative positions of continentsand Antarcticgla- ciation,whereas regional air masses,submarine topography, and coastline shape affectlocal processes such as upwelling. I hypothesize that the long-termdevelopment of these abiotic processes has influencedthe relative diversityand communitycomposition of North Pacific seabirds. To explore this hypothesis,I divided the historyof North Pacific seabirds into seven intervalsof time. Using published descriptions,I summarized the tectonicand oceanographic events that occurred during each of these time intervals,and related changes in species diversityto changes in the physical environment.Over the past 95 years,at least 94 species of fossil seabirds have been described from marine deposits of the North Pacific. Most of these species are from Middle Miocene through Pliocene (16.0-1.6 Ma) sediments of southern California, although species from Eocene to Early Miocene (52.0-22.0 Ma) deposits are fromJapan, -

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. Grecian Bachelor of Science (Hon), Memorial University of Newfoundland, 1996 A Thesis Submitted in Partial Fulfilment of the Requirements for the Degree of Master of Science in the Graduate Academic Unit of Biology Supervisors: A.W. 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. -

Breeding success was high Razorbills (73%) and Common Guillemots (85%), but low in Brünnich’s Guillemots Brünnich Guillemots (51%), largely due to low hatching success.

Benjamin Becker, Ph.D. National Park Service BREEDING ECOLOGY OF PIGEON GUILLEMOTS (CEPPHUS COLUMBA) ON ALCATRAZ ISLAND, CALIFORNIA Victoria Leslie Seher San Francisco, California 2016 This study compared the breeding ecology and diet of Pigeon Guillemots (Cepphus columba) from an urban estuarine colony (Alcatraz Island) and a remote oceanic colony (Southeast Farallon Island) to better understand how spatial differences and current management influence the two colonies. I used video cameras inside nest sites to help monitor the breeding phenology, reproductive success, and prey delivered to chicks on Alcatraz Island in 2015 and 2016. Data collected in this study were compared with data collected by Point Blue Conservation Science on Southeast Farallon Island. Results show similarities in breeding phenology between the two colonies, although the breeding start date was earlier on Alcatraz in 2016 by 12 days. Productivity was higher on Alcatraz in both years with 0.73 and 0.83 fledged chicks/pair while productivity dropped on Southeast Farallon Island from 0.65 fledged chicks/pair in 2015 to 0.30 fledged chicks/pair in 2016. -

V6X2G9 Canada Received 9 April 2003, accepted 11 October 2003 SUMMARY NEVINS, H. M. & CARTER, H. R. Age and sex of Common Murres Uria aalge recovered during the 1997-98 Point Reyes Tarball Incidents in central California. Marine Ornithology 31: 51-58. We examined 1,138 Common Murre Uria aalge carcasses recovered along the central California coast from November 1997 through March 1998 during the Point Reyes Tarball Incidents, a prolonged oiling event traced to the sunken vessel S. S. Jacob Luckenbach. We used head plumage, supraorbital ridge, and bursa of Fabricius, to classify age among carcasses as hatch-year (HY), or after-hatch year (AHY). We then separated AHY birds into two maturity categories based on gonad development: subadult and adult. The observed age class composition (14.6% HY, 37.6% subadult, and 47.8% adult) was not different from expected values generated with a stage-based matrix model that assumed a year-round resident population. The sex ratio for HY birds was equal (1.2:1), indicating little difference in at-sea distribution among male and female HY birds during winter. We found male-biased sex ratios in subadult (1.6:1) and adult (1.5:1) age classes.
