We used processed eBird relative abundance data from 2020 provided by the Lab of Ornithology, Cornell University (Fink et al, 2021) to develop bald and golden eagle relative abundance maps. eBird relative abundance values are a modeled data product that represent the average number of eagles of each species expected to be seen by an expert eBirder who observes for 1 hour at the optimal time of day for detecting the species, and who travels no more than 1 kilometer during the observation session (see eBird FAQs at ebird.org/spain/science/status-and-trends/faq#mean-relative-abundance). The strength of the relative abundance models is the standardization of approach across the entire contiguous U.S. and the ability...
This map shows where wind projects in the coterminous U.S. are eligible to apply for a wind energy general permit or a wind energy specific permit under the USFWS Eagle Incidental Take Rule (Permits for Incidental Take of Eagles and Eagle Nests; 89 FR 9920;) and final Environmental Assessment. Wind facilities are eligible for a general permit or a specific permit based, in part, on eagle abundance information. Existing projects that are only eligible for specific permits may be determined to qualify for a general permit upon Service review of their permit application. See the Federal Register Notice and USFWS Eagle Management website for additional information about the Rule. Visit the ArcGIS Online site for a...
