    Nocturnal Foraging by Red-Legged Kittiwakes, a Surface Feeding Seabird That Relies on Deep Water Prey During Reproduction. by Nobuo Kokubun, Takashi Yamamoto, Dale M Kikuchi, Alexander Kitaysky, Akinori Takahashi

    Published 2015-01-01
    “…Red-legged kittiwakes are presumed to be a nocturnal surface-foraging seabird that feed almost entirely on deep water Myctophidae fishes. …”

    Inter-Specific and Intra-Specific Competition of Two Sympatrically Breeding Seabirds, Chinstrap and Gentoo Penguins, at Two Neighboring Colonies by Won Young Lee, Seongseop Park, Kil Won Kim, Jeong-Hoon Kim, Jong-Ku Gal, Hosung Chung

    Published 2021-02-01
    “…To test the hypothesis that intra-specific competition is more intense than inter-specific competition owing to a lack of niche partitioning, we estimated the foraging area and diving depths of two colonial seabird species at two neighboring colonies. Using GPS and time-depth recorders, we tracked foraging space use of sympatric breeding Chinstrap and Gentoo penguins at Ardley Island (AI) and Narębski Point (NP) at King George Island, Antarctica. …”

    Little auks under the midnight sun: diel activity rhythm of a small diving seabird during the Arctic summer by Katarzyna Wojczulanis-Jakubas, Piotr Wąż, Dariusz Jakubas

    Published 2020-02-01
    “…Here, we examine periodicity and patterns of daily activity (colony attendance and foraging) in a High-Arctic seabird, the little auk (Alle alle). We demonstrated a regular rhythm of colony attendance at the population level, with birds being the most abundant in the colony during hours of relatively low sun elevation. …”

    Differential responses of seabirds to environmental variability over 2 years in the continental shelf and oceanic habitats of southeastern Bering Sea by T. Yamamoto, N. Kokubun, D. M. Kikuchi, N. Sato, A. Takahashi, A. P. Will, A. S. Kitaysky, Y. Watanuki

    Published 2016-04-01
    “…George Island, the largest seabird colony in the region, were recorded using GPS loggers, and blood samples were taken to examine their physiological condition and isotopic foraging niche in a given year. …”

    Nestboxes augment seabird breeding performance in a high‐density colony: Insight from 15 years of monitoring data by Brian Burke, Darren P. O'Connell, David Kinchin‐Smith, Síofra Sealy, Stephen F. Newton

    Published 2022-07-01
    “…Abstract The provision of artificial nest structures is used in the conservation of a broad range of bird groups including raptors, owls, ducks, passerines and seabirds, with varying degrees of success. Artificial nestboxes have been provided to increase the density and breeding success of Roseate Tern pairs at colonies in north‐west Europe and the eastern seaboard of the USA and Canada, but their effect on breeding productivity has never been comprehensively quantified. …”

    Looming-eyes buoys fail to reduce seabird bycatch in the Icelandic lumpfish fishery: depth-based fishing restrictions are an alternative by Yann Rouxel, Hólmfríður Arnardóttir, Steffen Oppel

    Published 2023-10-01
    “…Bycatch in gillnets from lumpfish (Cyclopterus lumpus) fisheries is an important conservation issue in the north Atlantic, with up to 30 000 seabirds potentially killed each year. To date, no technical solutions exist to reduce the bycatch of seabirds in gillnet fisheries, but research on above-water bird deterrents as a form of bycatch mitigation has shown promising results. …”

    Assessing the importance of individual- and colony-level variation when using seabird foraging ranges as impact assessment and conservation tools by Cleasby, IR, Owen, E, Butler, A, Baer, J, Blackburn, J, Bogdanova, MI, Coledale, T, Daunt, F, Dodd, S, Evans, JC, Green, JA, Guilford, T, Harris, MP, Hughes, R, Newell, MA, Newton, SF, Robertson, GS, Ruffino, L, Shoji, A, Soanes, LM, Votier, SC, Wakefield, ED, Wanless, S, Wilson, LJ, Bolton, M

    Published 2023
    “…<p>Knowledge of seabird distributions plays a key role in seabird conservation and sustainable marine management, underpinning efforts to designate protected areas or assess the impact of human developments. …”

    Simultaneous multi-colony tracking of a pelagic seabird reveals cross-colony utilization of a shared foraging area by Dean, B, Kirk, H, Guilford, T, al., E

    Published 2015
    “…Here, we present a large (528 foraging trips, 169 individuals), multi-year, multi-colony GPS tracking dataset mostly collected simultaneously at 4 breeding colonies across the core breeding range of a colonially breeding pelagic seabird, the Manx shearwater Puffinus puffinus. Foraging areas were identified by filtering GPS locations (using speed, time of day, and turning angle), validated on a subset of 25 birds carrying co-deployed depth loggers to maximise inclusion of foraging and feeding behaviour. …”
