Description:
Abstract:
These are raw data from a stratified random survey 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.
Purpose:
This was the first systematic inventory of birds in the lowlands (elevation below 100 m) of the Alaska Peninsula to determine their breeding distributions and habitat associations in this remote region. These data form a baseline to monitor any future changes in bird distribution and abundance on the Alaska Peninsula.

Classification_System_Modifications:
Taxonomy within the class aves (birds) is provided in the data tables. We follow the most current (as of April 2022) taxonomic designations of the eBird/Clements Checklist of Birds of the World: v2021 (which closely aligns with American Ornithological Union's (AOU) Checklist of North American Birds (7th edition, with updates through the 60th supplement.)
Taxonomic_Procedures:
Species were identified by skilled observers in the field based on general appearance of feathers and plumage, behavior, and vocalization.
Taxonomic_Completeness:
Provided here is the classification of birds to the rank of class. Further details of taxonomy are provided in the table "birdInventory_taxonomy_AKPen_tibbitts_2004_2007.csv" included with this data package.

Attribute values fall within expected ranges and data were checked for duplication and omission.
Completeness_Report:
Point count locations that fell outside the boundaries of the plots were removed from the analysis. This only occurred with two point counts in 2004 due to human error.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Positions were obtained using handheld Garmin GPSs. Positional accuracy estimated to be within 3 meters.

Methodology:
Methodology_Type: Field
Methodology_Description:
Observers conducted 792 10-min point counts of birds within 52 5-km × 5-km plots that were randomly selected and stratified by elevation and land cover. Surveys were conducted from mid-May to early June. In each plot all species encounters as well as physical conditions were recorded on plot field data forms. Further, species, their behavior, and habitat class at each point were recorded on the point field data forms.
Methodology:
Methodology_Type: Field
Methodology_Description:
At each point visited, observers recorded the percent cover of all vegetation types within 50m of the point in dense vegetation (e.g., alder thickets, n = 96 points) and 150 m of the point in open vegetation (e.g., sedge meadows, n = 607 points). Observers took one image of vegetation at each of the the four cardinal directions to create a baseline for any future studies of vegetation change in the region.
