Intertidal mudflats and the conservation of migratory shorebirds
Migratory shorebirds rely on intertidal habitats that are increasingly threatened by habitat loss, human disturbance, and climate change. Investigating habitat availability, its influence on shorebird populations and how to prioritise conservation efforts is critical to inform conservation …

Community Compostition and Microhabitats of Macroinvertebrates on Sandbars within the Lower Missouri River as a Food Source for Foraging Migratory Shorebirds
… these microhabitats as a source of food for migratory shorebirds. Nearly 40 species of shorebirds migrate between breeding and wintering grounds through interior North America every year. There are documented cases of significant threats to 36 species (72%) during migration. Migratory …

Building a Comprehensive Understanding of Disturbance Mitigation in Migrating Shorebirds
Human disturbance is a serious threat facing shorebirds, and reducing disturbance presents a significant conservation challenge. It requires an understanding of the complex factors that influence both shorebird biology and human behavior related to shorebirds and coastal environments. This thesis …

Influence of Habitat Characteristics on Wetland Bird Abundance and Species Richness at Ordway Prairie, South Dakota
… tricolor) were the most common breeding shorebirds. Lesser yellowlegs (Tringa flavipes) were the most commonly occurring migrant shorebird. Abundance varied between 1998 and 1999 for some species. Multiple regression models were used to explore possible reasons for that variation. Surface …

The Effects of Weather on Wetland Habitat Conditions and Shorebirds During Spring and Fall Migration in Northwest Minnesota
… at Agassiz National Wildlife Refuge for migratory shorebirds between seasons and years with variable weather conditions. Habitat conditions between 2002, a wet year, and 2003, a dry year, varied considerably. The percent of flooded off-refuge wetlands varied between 100% in spring 2002 to …

A System-Level Analysis of Migratory Shorebird Habitat Use, Diet, and the Influence of Climate-Driven Ecosystem Change in the Virginia Barrier Islands
Migratory shorebirds rely on high-quality coastal staging habitats to refuel during migration, but these sites are threatened by climate change. The Virginia barrier island system supports over 100,000 shorebirds annually, including federally threatened red knots (Calidris canutus rufa) and other …

Estimating occupancy and abundance of shorebirds through aerial surveys in the Illinois river valley
"Shorebirds are one of multiple guilds of wetland birds that have been experiencing population declines over the last 50 years. These species migrate long distances between northern breeding grounds and southern wintering grounds, and many need to stop and refuel along the way. The Illinois River …

Aspects of the ecology of migrant shorebirds (Aves: Charadrii) at the Berg River estuary, South Africa
… of the estuary for Palearctic-breeding migratory waders and to identify the factors affecting their distribution, abundance and behavioural patterns. The findings were related to the dispersion patterns of waders on the east Atlantic seaboard, and their significance was evaluated in the …

Demography of a declining Dunlin (<i>Calidris alpina arcticola</i>): influences on adult survival and mate fidelity of an Arctic-breeding migratory shorebird
… rates is crucial in conservation efforts. For migratory birds, vital rates can be impacted by conditions experienced throughout the year. Migratory shorebird populations are rapidly declining, including populations of Dunlin (<i>Calidris alpina arcticola</i>), an Arctic-breeding shorebird. …
