About
Dataset summary
The American Woodcock Singing-ground Survey (SGS) is a long-term road-side survey that began in 1968. The SGS is administered by the US Fish and Wildlife Service (USFWS) in cooperation with the Canadian Wildlife Service (CWS), 19 state agencies, 6 provincial agencies, and volunteers. Data from the SGS provide natural resource managers with an index of American Woodcock (Scolopax minor) population abundance by taking advantage of the conspicuous breeding call of the male woodcock. When obtaining data via the website, you will have access to count data (total heard peenting) at the stop level for individual states and provinces from 2024-present. Eventually historical count data from 1968-2023 will be uploaded into NatureCounts for public use. Until that time, please contact Rebecca Rau, Rebecca_rau@fws.gov with any historical data requests
Season(s) and frequency
A subset of routes are surveyed one time each spring on an annual basis.
Geographic area covered
Coverage includes states and provinces that fall within the central and northern portions of the woodcock's breeding range. A visual image of this can be found in Figure 1 within the annual population status report (https://www.fws.gov/library/collections/american-woodcock-population-status-reports).
Primary species covered
American Woodcock (Scolopax minor)
Goals
SGS data have been used to develop population and habitat goals for the American Woodcock Conservation Plan (https://www.fws.gov/media/american-woodcock-conservation-plan) and provide the primary population metrics used for the US Harvest Strategy (https://www.fws.gov/media/interim-american-woodcock-harvest-strategy).
