Abstract Shorebirds are declining to a greater extent than many other avian taxa around the world. In North America, shorebirds, along with aerial insectivores and grassland birds, have some of highest proportions species any group. Here, we apply new hierarchical Bayesian model analyze shorebird migration monitoring data from across 1980 2019, present most recent available estimates trends for 28 species. Point survey-wide in abundance were negative 26 (93%). Despite challenges low...
Abstract Long-distance migrants are assumed to be more time-limited during the pre-breeding season compared post-breeding season. Although breeding-related time constraints may absent post-breeding, additional factors such as predation risk could lead that were previously underestimated. By using an automated radio telemetry system, we pre- and movements of long-distance migrant shorebirds on a continent-wide scale. From 2014 2016, deployed transmitters 1,937 individuals 4 shorebird species...
Abstract We compiled a >50‐year record of morphometrics for semipalmated sandpipers ( Calidris pusilla ), shorebird species with Nearctic breeding distribution and intercontinental migration to South America. Our data included >57,000 individuals captured 1972–2015 at five locations three major stopover sites, plus 139 museum specimens collected in earlier decades. Wing length increased by ca. 1.5 mm (>1%) prior 1980, followed decrease 3.85 (nearly 4%) over the subsequent 35 years....
Abstract For most shorebird species, our understanding of the basic limiting factors and when or where they operate during annual cycle is currently inadequate to either understand ongoing declines effectively allocate conservation resources for recovery. Whimbrels (Numenius phaeopus) exhibit delayed recruitment have low fecundity, populations with such life-history traits are often vulnerable increases in adult mortality. We tracked 33 satellite transmitters 12,802 bird-days investigate...
Peregrine falcons (Falco peregrinus) have undergone a steady hemisphere-wide recovery since the ban on DDT in 1973, resulting an ongoing increase level of danger posed for migrant birds, such as Arctic-breeding sandpipers. We anticipate that response semipalmated sandpipers (Calidris pusilla) adjusted migratory behaviour, including shift stopover site usage towards locations offering greater safety from falcon predation. assessed sandpiper within Atlantic Canada Shorebird Survey dataset....
Neima, S. G., D. J. Hamilton, C. L. Gratto-Trevor, and Paquet. 2020. Intra- interannual regional fidelity of Semipalmated Sandpipers (Calidris pusilla) during migratory stopover in the upper Bay Fundy, Canada. Avian Conservation Ecology 15(1):14. https://doi.org/10.5751/ACE-01561-150114
Abstract Each year hundreds of millions birds cross the Atlantic Ocean during peak tropical cyclone activity. The extent and consequences migrant-storm interactions remain unknown. We tracked whimbrels from two populations (Mackenzie Delta; Hudson Bay) to examine overlap between migration routes storm activity both frequency consequence encounters. Here we show that Mackenzie Delta Bay follow different across ocean experience dramatically rates departed North America Canada, made long (...
Many long-distance migratory birds use habitats that are scattered across continents and confront hazards throughout the annual cycle may be population-limiting. Identifying where when populations spend their time is fundamental to effective management. We tracked 34 adult whimbrels ( Numenius phaeopus ) from two breeding (Mackenzie Delta Hudson Bay) with satellite transmitters document structure of cycles. The differed in pathways seasonal schedules. Mackenzie made long (22,800 km) loop...
The objective of this study was to determine the implications extreme tidal events on duration stay and behavior Semipalmated Sandpipers (Calidris pusilla) during migratory stopover in Cobequid Bay, Nova Scotia. This area is part Bay Fundy experiences largest range world. Radiotelemetry used monitor 30 adult seven juvenile Sandpipers. Adults arriving early migration period experienced a greater number high tides (> 15 m) that submerged preferred roost sites, stayed average 8.1 days longer...
Migrant shorebirds operate within a series of landscapes and must adjust their daily activities to achieve seasonal time energy objectives. Night roosts are essential landscape elements that provide safety from predators for many shorebird species. What costs migrants incur use night how these vary across staging sites poorly understood. We tracked 42 adult whimbrels Numenius phaeopus with satellite transmitters used locations delineate 39 during spring fall migration. daytime measure...
The Bay of Fundy, Canada is a critical staging area for Semipalmated Sandpipers ( Calidris pusilla ) during post-breeding migration. Recent range-wide population declines and changes in diet migratory timing the Fundy prompted re-examination ecology, including length stay (last estimated 1981), which used calculating estimates. We radio-telemetry Motus Wildlife Tracking System to estimate individual departure conditions 159 2013 2014. Using tracking data we compared two estimation methods,...
Abstract Semipalmated Sandpipers (Calidris pusilla) are Arctic-breeding shorebirds that use staging sites in Atlantic Canada during their southbound migration to South America. The upper Bay of Fundy is recognized as a critical area, but hundreds smaller outside the also host and have received comparatively little attention. Using Motus Wildlife Tracking System, we tracked adult juvenile identified different strategies used by sandpipers tagged inside Fundy. Birds remained there, while birds...
Semipalmated Sandpipers ( Calidris pusilla ) are Arctic-breeding shorebirds that use staging sites in Atlantic Canada during their annual migration to South America. The Bay of Fundy has long been recognized as a critical site for migrating and supports large prey base. diet adult sandpipers the is flexible but juveniles, which arrive later, not well documented. Comparatively little known about base how it utilized by at outside Bay. Plasma metabolite measures can provide useful insight...
Abstract The Purple Sandpiper ( Calidris maritima ) is a medium‐sized shorebird that breeds in the Arctic and winters along northern Atlantic coastlines. Migration routes affiliations between breeding grounds wintering are incompletely understood. Some populations appear to be declining, future management policies for this species will benefit from understanding their migration patterns. This study used two mitochondrial DNA markers 10 microsatellite loci analyze current population structure...
Large numbers of Semipalmated Sandpipers (Calidris pusilla) use the Bay Fundy, Canada, as a stopover site during their southbound migration from breeding to wintering grounds. The species exhibits geographic cline in bill length on grounds (larger east). Based previous analysis morphometric traits that detected small temporal decline length, it has been suggested observed declines Sandpiper population staging Fundy were driven by disproportionate loss eastern population. New data collected...

Abstract Semipalmated sandpipers are Arctic breeding shorebirds that migrate to South America during the non‐breeding season. Little work has been done understand daily movements, foraging habits and metabolic state of this species on stationary nonbreeding grounds. Our was conducted at Banco dos Cajuais Western Hemisphere Shorebird Reserve Network (WHSRN) site in Northeast Brazil. We captured semipalmated February March 2019 2020 attached nanotags monitor their movements. Blood samples were...
Abstract Addressing urgent conservation issues, like the drastic declines of North American migratory birds, requires creative, evidence-based, efficient, and collaborative approaches. Over 50% monitored shorebird populations have lost over their abundance since 1980. To address these declines, we developed a partnership scientists practitioners called Shorebird Science Conservation Collective (hereinafter “the Collective”). Here, present this successful case study as an example for others...
We quantified egested microplastics for three shorebird species (Western Sandpiper Calidris mauri, Dunlin alpina, and Semipalmated pusilla) by collecting fecal samples at major stopover sites on the Pacific Atlantic coasts of Canada in 2022. The sampling effort resulted a total 133 individual samples, 93 from 40 sites. Frequency occurrence was generally low ranged species: Western (FO=13%, n = 11/87), (FO=17%, 1/6), (FO=3%, 1/40). Polyester most common polymer (n=6), followed polypropylene...
