These data pertain to bird point surveys collected from 30 April 2016 to 12 May 2016 and 23 May 2016 to 25 June 2016 at four bottomland hardwood restoration sites in northeastern Indiana. The data are a single monitoring occasion with the purpose of documenting bird communities across these sites. During the time of collection, sites contained areas of hardwood planting ranging in age from 2 to 22 years, mature forest, old fields, and cropland. Each site was surveyed at multiple, fixed bird survey points; each point was visited at least 7 times. Bird point surveys were conducted between sunrise and 11:00 Central Daylight Time, lasted 5 minutes, and aimed to record all bird species seen and heard within 100 meters of the survey point center. Taxonomic and other classification information is provided for each bird taxon. Other classifications include designation of species as Partners in Flight regional conservation concern species and/or interior forest specialists. Also given are the spatial coordinates of each survey point with a rough habitat classification of each point, either woody plant-dominated or grassland-like. Bird survey data contain detection and non-detection data for 106 bird taxa within 100 meters during each survey, as well as observations of flyover species. Also included is R code to resample the data to create resampled datasets for use in rarefaction-based analyses. Values within the resampled dataset include site, number of points surveyed (samples), number of survey visits per point (subsamples), cumulative number of resampling occasions, presence of grassland-like habitat points among the samples within a resampling occasion., presence of woody plant-dominated habitat points among the samples, and detection/non-detection of different landbird species.

Avian point count, vegetation, and management data from surveys in Northern New England at four National Wildlife Refuges (NWRs), Baxter State Park, and prviate lands in Northern Maine surveyed during the breeding and postbreeding season bewteen 1 June and 4 August 2013 to 2015. NWRs include Nulhegan (Silvio O. Conte), Umbagog, Moosehorn, and Aroostook. This data release includes five zip folders which contain the data and metadata for various aspects of the project as briefly described in the metadata below

Bird surveys were conducted in 1981, 1989, 1994, 2000, 2005, 2007, 2008, and 2012. From these data we calculated species-specific density and abundance estimates. We conducted separate trends assessments for the Interior (long [1981-2012] and short [2000-2012]) and the Exterior (surveyed 2000-2012) portions of the Alakai Plateau, and using abundance estimates for native species from 2000-2012, we fit a linear and exponential growth model to the population numbers of each species to evaluate time to extinction.

This dataset contains records from bird point count and vegetation surveys conducted at 71 sites in southern Iowa in 2022 and 2023. All sites had recently implemented a management practice aimed at increasing habitat quality for northern bobwhite. We conducted surveys at 1-3 points per site and visited each point 3 times between May 15 and July 31 each year. Some sites were visited in both years and others were only surveyed in one year. We also collected vegetation data from points to assess fine-scale vegetation characteristics.

This dataset includes information on detections of Bachman's Sparrow, Northern Bobwhite, and Red-cockaded Woodpecker at 161 locations in Georgia, USA. In addition to detections of birds and corresponding detection covariates (date, time, temperature, and observer), habitat metrics derived from satellite imagery and on-the-ground vegetation measurements are included.
