Shoreline bird surveys were conducted in Kalaupapa National Historical Park to inventory avian species diversity and relative abundance. Seasonal migrants (waterfowl, shorebirds) were the primary focus of the routine surveys, but seabirds, raptorial species, and native waterbirds were also recorded as encountered. The coastline of Kalaupapa National Historical Park was surveyed once over a two day period, 5-6 April 2005. The park coast consists of sandy and rocky beaches, steep rock cliffs adjoining grassy pastures, and uninhabited offshore islets. Pacific golden plovers, wandering tattlers, and ruddy turnstones are common seasonal migrants that were observed along the survey route. Four seabird species common to the Hawaiian Islands, great frigatebird, wedge-tailed shearwater, re-tailed tropicbird, and white-tailed tropicbird were observed as well. An unknown booby species, most likely red-footed booby was seen on the offshore islets. All passerine species observed along the shoreline route were non-native. No waterfowl or raptors were observed during the survey. Also included are GIS shapefiles of the shoreline bird inventory route taken, and all species detected during the inventory.

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 data release contains the point-transect distance sampling records of forest bird survey collected in the Kohala Mountain complex in 2017, including survey point IDs, distance to detected birds, sampling conditions, ohia phenology, habitat classifications and background noise levels. This data release consists of one tabular dataset.

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.

The Kahuku Unit of the Hawai`i Volcanoes National Park (HAVO) was surveyed for native and non-native birds from January to September of 2005. Bird habitat comprised of forest, woodland, and grassland was divided into five separate regions, and these were surveyed with variable circular plot count methodology to generate estimates of abundance and occurrence. Sampling coverage was more intensive (i.e. several times more count transects and stations) than in past surveys, for more accurate estimates of range and population size. In addition to point counts, we recorded incidental observations to supplement the survey. The database contains detection data from the inventory for all bird species except the three endangered species (Hawaii Akepa, Hawaii Creeper, and Akiapolaau). Also included are the GIS shapefiles of the transects that were surveyed for the inventory.

Eight-minute point-transect distance bird surveys were collected in and around Haleakala National Park from 1993-2008. This dataset contains the location, species, and distance to detected birds, as well as identifying initials to distinguish among observers.

This data describes the bird community in the lowland region of Hawaii Volcanoes National Park. Birds were surveyed using the line transect method, which includes measuring species, distance to bird, angle to bird, angle to trail, coordinates of beginning and end of trail and of each observation.
