eBird Status & Trends Field Sparrow occurrence probability
Description
A RasterStack of the expected probability of occurrence of Field Sparrow from the eBird Status & Trends project. Each of the 12 layers in the stack represent the estimated occurrence for a given month of the year over a regular grid of points covering the full range of the species. To reduce file size, these data have been aggregated from the native 2.96 km spatial resolution and weekly temporal resolution to monthly, 14.8 km resolution.
Usage

Format
An object of class RasterStack of dimension 193 x 225 x 12.
