These data were compiled to evaluate the reproductive ecology of Agassiz's desert tortoises (Gopherus agassizzi) in the Sonoran Desert of California using two populations within Joshua Tree National Park, including five reproductive seasons that spanned 20 years (1997-1999, 2015-2016). Compared to their conspecifics inhabiting the Mojave Desert, the reproductive ecology of G. agassizii in the Sonoran Desert is understudied. Climatic variation between the two deserts can affect reproductive ecology, including fecundity and clutch phenology. Mature female tortoises (straight-line carapace length ≥ 20 cm) outfitted with radiotransmitters were located and X-radiographed approximately every 10-14 days during the reproductive...

Distribution of Black Oystercatcher habitat in coastal British Columbia showing relative abundance (RA) by season and overall relative importance (RI). RI is based on project region and not on the province as a whole. British Columbia has been collecting coastal resource data in a systematic and synoptic manner since 1979. Resource information is collected using peer-reviewed provincial Resource Information Standards Committee which include standards for data management and analysis

This data is a companion to the manuscript titled "Data integration reveals dynamic and systematic patterns of breeding habitat use by a threatened shorebird". Advances in both remote sensing and analytical tools for spatial data have allowed for the integration of dynamic processes into species distribution models. We developed a spatiotemporal model of breeding habitat use and density for a federally threatened shorebird (piping plover, Charadrius melodus) by integrating a 20-year (2000 – 2019) nesting dataset with opportunistic, volunteer collected (eBird), sightings. Piping plovers are an ideal candidate for dynamic habitat models because this species depends on habitat created and maintained by highly variable...
We present two tabular data sets representing values to estimate apparent natal and adult survival and transition probabilities between breeding location states used in a multievent capture-mark-resight model for piping plover adults and hatch year birds in the Northern Great Plains from 2014-2019 focusing on four study areas: U.S. Alkali Wetlands (ALK), Lake Sakakawea (SAK), Garrison Reach of the Missouri River (GRR), and Lake Oahe (OAH). In addition, several covariates were included representing habitat and social variables.

This data set is part of a data release as a companion to a published manuscript titled "Low renesting propensity and reproductive success make renesting unproductive for the Piping Plover, Charadrius melodus." The Condor: Ornithological Applications. Upon reproductive failure, many bird species may make a secondary attempt at nesting. This data set includes four tabular digital data files representing values related to renesting propensity, renesting intervals, renest reproductive success, and nest survival of Piping Plovers (Charadrius melodus). We followed nests and unique breeding adults from 2014 - 2016 in the Northern Great Plains of the US. This included river and reservoir habitats present on the Missouri...

We present two tabular digital data files representing values related how the presence of hetero- and conspecifics influence nest and chick survival for two listed migratory species breeding on the Missouri River; piping plover (Charadrius melodus) and least tern (Sternula antillarum). We followed 2,507 piping plover nests, 3,251 uniquely banded piping plover chicks, 1,060 least tern nests, and 1,377 uniquely banded least tern chicks from 2007 - 2009, 2012- 2016 in the Northern Great Plains of the US. This included river and reservoir habitats present on the Missouri River in North and South Dakota. Not all study areas were studied in all years. The nest survival dataset includes values for use with the Shaffer...

Two tabular data sets representing values to examine survival estimates for piping plover nests and chicks in the Northern Great Plains from 2014-2016. We focused on four study areas: U.S. Alkali Wetlands, Lake Sakakawea, Garrison Reach of the Missouri River, and Lake Oahe spanning eastern Montana, North Dakota, and South Dakota. We followed nests to completion, either success or failure, and created capture histories for uniquely banded chicks.

We investigated methods to estimate the number of nests of waterbirds at a large, mixed-species colony at Chase Lake National Wildlife Refuge in south-central North Dakota in 2012 and 2013. The data were summarized and used in the analyses for a publication in a U.S. Geological Survey Open-File Report. The data consist of two data sets that were used to assess visible-nest counts for ciconiiform species conducted from the perimeter of nesting areas (hereafter perimeter counts) and observational surveys from fixed points outside the colony to count flights of adult ciconiiforms in and out of the colony (hereafter flightline surveys) as alternatives to within-colony counts of ciconiiform nests.

These maps were developed to support an effort to understand the spatial characteristics of piping plover (Charadrius melodus) nesting habitats. The maps show the expected nesting habitat distributions and piping plover intensity between 2000 and 2021 in the U.S. Prairie Pothole Region.

We present a tabular data set representing values to estimate apparent hatch-year survival to adulthood and natal dispersal probabilities between two breeding groups of the Northern Great Plains piping plover (Charadrius melodus) used in a multievent capture-mark-resight model from 2014-2019. Focusing on the Northern Missouri River and U.S. Alkali Wetlands breeding groups. In addition, several covariates were included representing habitat and social variables.
We present two tabular data sets representing values to examine sources of variation in natal and breeding dispersal distances for piping plovers breeding in the Northern Great Plains from 2014-2019 focusing on four study areas: U.S. Alkali Wetlands, Lake Sakakawea, Garrison Reach of the Missouri River, and Lake Oahe. We included habitat variables, and conspecific densities in both datasets and include nest fates and mate fidelity in the breeding dispersal dataset.

We present a tabular data set representing values used to evaluate hypotheses of breeding habitat selection for immigrants and returning Northern Great Plains piping plovers (Charadrius melodus) from 2014 – 2019. The associated manuscript uses network analysis approach to evaluate five hypotheses of habitat selection. In this approach breeding locations were nodes and successive year breeding attempts form the edges (immigration) and self-loops (fidelity). Included in the dataset are covariates of habitat amount, conspecific density, and habitat quality, as well as other fields used in the analysis. In addition, we include descriptive breeding location-specific metrics from the network graphs.
This dataset presents four tabular data files that evaluate the effect of predator exclosures around piping plover (Charadrius melodus) nests on plover nest, chick, within-season, and annual adult survival. During 2014-2016, we designed an experiment to examine nest (n = 418), chick (n = 453), and adult (n = 367) survival at alkaline wetlands of the Northern Great Plains. Alkaline wetlands were divided between treatment wetlands and control wetlands (no exclosures placed anywhere on wetland). Field crews aimed to place predator exclosures around half of all plover nests found resulting in three treatment types: uncaged nest on control wetland, uncaged nest on treatment wetland, and caged nest on treatment wetland....

This data set is part of a data release as a companion to a manuscript titled "Foraging movements and colony attendance of least terns (Sternula antillarum) on the central Platte River". This data release includes three tabular digital data file representing movement patterns, behaviors, and foraging success of least terns that nested on sandpits near the Platte River during 2009 and 2010. Movement, behavior, and foraging data were collected at the sandpits where birds nested as well as on riverine sites.
