Resource Abstract:
- description: The purpose of the Midwinter Bald Eagle survey is to monitor the status of Bald Eagle wintering populations in
the contiguous United States by estimating national and regional count trends, overall and by age class. Each January, several
hundred individuals count eagles along standard, non-overlapping survey routes. Nationwide counts of eagles were coordinated
by the National Wildlife Federation from 1979 until 1992, when the Raptor Research and Technical Assistance Center (now U.S.
Geological Survey (USGS), Snake River Field Station) assumed responsibility for overseeing the count. Initial objectives of
the survey were to establish an index to the total wintering Bald Eagle population in the lower 48 states, to determine eagle
distribution during a standardized survey period, and to identify previously unrecognized areas of important winter habitat.
Beginning in 1984, National Wildlife Federation officials asked participants in each state to count eagles along standard
routes to provide data on count trends. Standard survey routes were defined as clearly described areas where eagles had been
observed in the past. Federation guidelines stipulated that standard surveys be conducted by the same number of experienced
observers using the same method (e.g., fixed-wing, helicopter, boat, vehicle) at approximately the same time of day each year.
In April 2007, the USGS established a partnership with the U.S. Army Corps of Engineers (USACE) to maintain the long-term,
national coordination of the survey, data analysis, and reporting. USACE will assume responsibility for coordinating the national
survey, organizing the results, maintaining the long-term database, and jointly compiling, analyzing, and reporting survey
data gathered with USGS following previously used methods (Steenhof et al. 2002) in 2010 and 2015. Guidance on when and how
to conduct the survey can be found via the external link provided with this record.; abstract: The purpose of the Midwinter
