Observation data and model covariate data from breeding bird inventory conducted during May-June 2004 and 2008 primarily in montane areas (>100 m above sea level) in Aniakchak National Monument and Preserve (Aniakchak NMP), Katmai National Park and Preserve (Katmai NPP), and Lake Clark National Park and Preserve (Lake Clark NPP) in southwestern Alaska. Observers conducted 1,021 point counts along 169 transects within 63 10-km × 10-km plots that were randomly selected and stratified by ecological subsection.

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 package contains six tables: 1) characteristics of bird survey sites, 2) vegetation classification at survey sites, 3) detections of all birds at survey sites, 4) behaviors of all birds at survey sites, 5) bird taxonomy and indication of conservation status, and 6) habitat information pertaining to survey site photographs. The objectives of the survey were to 1) use targeted field investigations to document as many bird species as possible that occur within Aniakchak during the breeding season, and 2) describe the distribution, habitat associations, and relative numbers of bird species occurring within Aniakchak during the breeding season.
