This data package contains two tables with habitat measurements from each sampling point used in avian point-transect surveys on the Seward Peninsula in 2012 and the locations of those sites. Measurements include percent cover and canopy height of alder (Alnus spp.), dwarf birch (Betula spp.), ericaceous shrubs (e.g., Empetrum, Vaccinium spp.), herbaceous, lichen (e.g., Cladonia spp.), and willow (Salix spp.).

This data package contains three tables: 1) avian point-transect survey data collected on the Seward Peninsula in 2012, 2) locations of all survey sites, and 3) an avian taxonomy table for reference.

This data package contains three tables: avian counts by species, habitat type, a covariate information used for analysis of bird surveys conducted between 2012 and 2014 on the Seward Peninsula, Alaska, as part of the USGS Changing Arctic Ecosystems Initiative. We conducted 1,208 point counts on 12 study blocks from 2012–2014 in northwestern Alaska, using repeated surveys to account for imperfect detection of birds. We considered the importance of shrub height, density of low and tall shrubs (i.e. shrubs >0.5 m tall), percent of ground cover attributed to shrubs (including dwarf shrubs <0.5 m tall), and percent of herbaceous plant cover in predicting bird abundance

This release includes data collected using stratified random surveys to inventory the birds breeding in lowlands (elevation below 100m) of the Alaska Peninsula, during summers 2004-2007. Data were collected at 792 survey points (10-minute point counts) on 52 5-km x 5-km plots. The data are in seven tables: 1) geographic coordinates of the bounding corners of each of the 52 survey plots, including environmental conditions at the time of the survey, 2) summary of all bird and mammal species encountered on each of the 52 plots before, during, and after the 10-min point counts, 3) geographic coordinates of each of the 792 bird count points and the vegetation cover at each point, 4) counts and behavioral observations of shorebirds and avian predators during 10-min point counts, 5) counts of all bird species not classified as shorebirds or predators that were encountered during 10-min point counts, 6) bird and mammal taxonomy references, and 7) inventory of the habitat photographs taken at each survey point.

This data release contains observational data from a breeding bird inventory using standardized point counts conducted during May-June 2005 in Kenai Fjords National Park (KEFJ), Alaska. It also includes a single survey conducted for owls on the night of 30 April 2005. Data tables include 1) survey route details, 2) survey point details, 3) survey habitat details at survey points, 4) bird detection distance and behavior, 5) bird checklists along survey routes and any evidence of breeding behavior, and 6) bird taxonomy. Although the survey design was optimized for diurnal landbirds, observers recorded all species of birds detected during and between point counts along survey routes. Data were also recorded systematically for a single mammal (red squirrel, Tamiasciurus hudsonicus) during the surveys.

Acoustic recorders can detect the presence of birds and these detections may be used for the purpose of population abundance or estimation. This monitoring project compared the abundance of tundra-breeding birds detected through both acoustic monitoring and observational surveys. The data package is comprised of four tables: (1) habitat type, including vegetation height at sites where acoustic recorders and human observer point counts occurred, 2) bird detections obtained using the observer methods, 3) bird detections obtained using the acoustic monitoring method, and 4) taxonomy table of bird species detected during both observer and acoustic recorder survey methods.
