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 3 km spatial resolution and weekly temporal resolution to monthly, 27 km resolution.
Usage
