The study of long-distance migration provides insights into the habits and performance organisms at limit their physical abilities. Arctic tern Sterna paradisaea is epitome such behavior; despite its small size (<125 g), banding recoveries at-sea surveys suggest that annual from boreal high breeding grounds to Southern Ocean may be longest seasonal movement any animal. Our tracking 11 terns fitted with miniature (1.4-g) geolocators revealed these birds do indeed travel huge distances...
Abstract An important provision of the Minamata Convention on Mercury is to monitor and evaluate effectiveness adopted measures its implementation. Here, we describe for first time currently available biotic mercury (Hg) data a global scale improve understanding efforts reduce impact Hg pollution people environment. Data from peer-reviewed literature were compiled in Global Biotic Synthesis (GBMS) database (>550,000 points). These provide foundation establishing biomonitoring framework...
Abstract The conservation of migratory marine species, including pelagic seabirds, is challenging because their movements span vast distances frequently beyond national jurisdictions. Here, we aim to identify important aggregations seabirds in the North Atlantic inform ongoing regional efforts. Using tracking, phenology, and population data, mapped abundance diversity 21 seabird species. This revealed a major hotspot associated with discrete area subpolar frontal zone, used annually by 2.9–5...
ABSTRACT Aim To identify the broad‐scale oceanic migration routes (‘marine flyways’) used by multiple pelagic, long‐distance migratory seabirds based on a global compilation of tracking data. Location Global. Time Period 1989–2023. Major Taxa Studied Seabirds (Families: Phaethontidae, Hydrobatidae, Diomedeidae, Procellariidae, Laridae and Stercorariidae). Methods We collated comprehensive dataset that included 48 pelagic migrating seabird species across Atlantic, Indian, Pacific Southern...
Upwelling regions are highly productive habitats targeted by wide-ranging marine predators and industrial fisheries. In this study, we track the migratory movements of eight seabird species from across Atlantic; quantify overlap with Canary Current Large Marine Ecosystem (CCLME) determine habitat characteristics that drive association. Our results indicate CCLME is a biodiversity hotspot for seabirds; all tracked more than 70% individuals used upwelling region. Relative richness peaked in...
The migrations and winter distributions of most seabirds, particularly small pelagic species, remain poorly understood despite their potential as indicators marine ecosystem health. Here we report the use miniature archival light loggers (geolocators) to track annual migration Sabine’s Gull Larus sabini , a ( c. 200 g) Arctic‐breeding larid. We describe migratory routes identify previously unknown staging sites in Atlantic Ocean, well main wintering area southern hemisphere. Gulls breeding...
Offshore wind energy development (OWED), while a key strategy for reducing carbon emissions, has potential negative effects to wildlife that should be examined inform decision making and adaptive management as the industry expands. We present conceptual framework guide long-term study of birds bats from OWED. This includes focus on exposure vulnerability determinants risk. For are exposed OWED, there three main interest may impact survival productivity: 1) collision mortality, 2) behavioral...
Little is known about the migration and movements of migratory tree-roosting bat species in North America, though anecdotal observations migrating bats over Atlantic Ocean have been reported since at least 1890s. Aerial surveys boat-based wildlife off Seaboard detected a possible diurnal event eastern red (Lasiurus borealis) September 2012. One was sighted approximately 44 km east Rehoboth Beach, Delaware during survey. Eleven additional were observed between 16.9 41.8 New Jersey, Delaware,...
We provide an overview of 25 years research at the East Bay Mainland station, in Qaqsauqtuuq Migratory Bird Sanctuary, Southampton Island, Nunavut. The earliest site targeted waterfowl and seabirds, but work since 2000 has focused on shorebirds. offers longest running study breeding shorebirds Canadian Arctic, with more than 1,800 nests 12 species monitored. Monitoring this contributed to our understanding ecology shorebirds, including factors influencing timing laying, habitat selection...
Mercury contamination has become a major concern in the Arctic, where elevated mercury deposition led to large increases exposure for some Arctic wildlife over past century. Chronic birds is known reduce reproductive success, which may ultimately result population declines. Many species of Arctic-breeding shorebirds are declining, and environmental contaminants, such as mercury, be an important factor. We quantified 10 shorebird breeding staging Alaska. analyzed 229 blood 73 feather samples...
Mandt's black guillemot ( Cepphus grylle mandtii ) is one of the few seabirds associated in all seasons with Arctic sea ice, a habitat that changing rapidly. Recent decreases summer ice have reduced breeding success and colony size this species Alaska. Little known about species' movements distribution during nine month non-breeding period (September–May), when changes extent composition are also occurring predicted to continue. To examine bird seasonal role guillemots, we deployed recovered...

Seabirds are declining globally, though the threats they face differ among and within species populations. Following substantial population declines at several breeding colonies, Leach's Storm-Petrel (<em>Hydrobates leucorhous</em>) was uplisted from Least Concern to Vulnerable by International Union for Conservation of Nature (IUCN) in 2016. Reasons these unclear, it is important identify faces across its global range guide research directions inform conservation efforts. We solicited...
Forage fishes are a critical food web link in marine ecosystems, aggregating hierarchical patch structure over multiple spatial and temporal scales. Surface-level forage fish aggregations (FFAs) represent concentrated source of prey available to surface- shallow-foraging predators. Existing survey analysis methods often imperfect for studying at scales appropriate foraging predators, making it difficult quantify predator-prey interactions. In many cases, general distributions species known;...
Extreme climate can negatively affect survival through increased physiological demands or by reducing prey availability. This have significant population-level consequences for organisms with low reproductive rates, such as seabirds. As an Arctic-breeding trans-equatorial migrant, Sabine’s gull (Xema sabini) is exposed to a profound variety of regimes during the year. Therefore, its annual may be affected broad-scale teleconnection patterns that influence regional variability. We used...
Abstract Aim The United States Atlantic Outer Continental Shelf (OCS) has considerable offshore wind energy potential. Capturing that resource is part of a broader effort to reduce CO 2 emissions. While few turbines have been constructed in U.S. waters, over dozen currently planned projects the potential displace marine birds, potentially leading effective habitat loss. We focused on three diving birds identified Europe be vulnerable displacement. Our research aimed determine their exposure...
The Ivory Gull (Pagophila eburnea) has a circumpolar breeding distribution and spends the entire year at high latitudes in Arctic North Atlantic oceans. Due to its remote locations nomadic wintering habits, little detailed information on ecology of this species exists, no estimates survival rate are available. Recent surveys have shown dramatic decline, with an estimated 250-350 pairs now Canada. Across range, was traditionally harvested by northern communities, and, although protected, it...
Quantifying the dynamics of populations is fundamental to understanding life-history strategies, and essential for population modeling conservation biology. Few details demography life history Sabine's Gull (Xema sabini) are known. Uniquely color banded Gulls breeding in East Bay, Southampton Island, Nunavut, eastern Canadian Arctic, were examined from 1998–2002 quantify vital rates. Generally, birds as chicks first returned area their third year, earliest case was confirmed at three years...
