Habitat use and trends of landbirds using National Wildlife Refuges along the northern Gulf of Mexico during migration

This data release includes measures of vertically-integrated reflectivity (VIR) and estimates of linear trends in VIR as observed by the Weather Surveillance Radar 1988 Doppler (WSR-88D) stations along the Gulf of Mexico during spring and autumn migrations from 2018-2020. The VIR is a measure of bird density and can be used to map the spatial distribution of birds as they leave stopover habitat and resume nocturnal migration. This data release also includes seasonal and multi-year summary statistics.

Factors affecting prey availability and habitat use of nonbreeding piping plovers (Charadrius melodus) in coastal Louisiana

Dataset includes observations of Piping Plovers made during winter shorebird surveys on Whiskey and Trinity Islands in Terrebonne Parish, Louisiana during the winter of 2013-2014. Attributes include location, behavioral, and microhabitat data as well as references to these data points in our local Access database.

Evaluating if abundance and behavior of shorebird species are related to restoration and habitat at Whiskey Island and Caminada Headland, Louisiana from 2012 to 2020

Barrier islands provide resources and ecological services that are integral to economic and environmental interests, such as protection of coastal infrastructure and providing habitat for wildlife. Over time, barrier islands may become eroded and experience land loss, which require management actions to restore island integrity. The process of restoring barrier islands can create new habitats but also alter existing habitats, which can impact the organisms depending on coastal habitats, such as the Endangered Species Act-listed (ESA) Piping Plover (Charadrius melodus) and Red Knot (Calidris canutus). Consequently, we aimed to understand the abundance and behavioral responses from a suite of shorebird species, including...
