Bird species frequency in Hawaii

Description

Frequency of bird species observation within 1km-squared grids in Hawaii as recorded in the eBird project. Not all counts are complete because some grids are sampled better than others (i.e. urban areas, birding hotspots).

Usage

data(hawaiibirds)

Format

list of three components: counts giving mean total counts of species in each grid, metadata_h giving information about each grid (i.e. latitude, longitude, and island), and metadata_w giving information about species taxonomic classification.

Details

This dataset was obtained as follows:

• All eBird observations in Hawaii were downloaded from the eBird website as of Oct. 2021

• Only complete checklists were retained

• Only non-X counts were retained

• Species were removed with fewer than 50 observations or that were spuhs

• Grids were defined by latitude/longitude rounded to two decimal places

• Grids were removed with fewer than 10 checklists

• Mean frequency of species in each grid was calculated based on the number of times a species was observed and the number of checklists submitted in that grid.

• Grids were assigned to one of each major Hawaiian island based on geographical coordinates.
