Midwinter Bald Eagle Survey


In 2012, TINS took over coordination of the annual Mid-Winter Bald Eagle Survey for the Tahoe basin, which usually takes place in mid-January. The count is part of the National Midwinter Bald Eagle Survey that was initiated by the National Wildlife Federation in 1979. Over the years, the coordination of the national effort has changed hands a few times, and is currently managed by the United States Army Corps of Engineers. Most recently the survey at Lake Tahoe was coordinated by the USFS Lake Tahoe Basin Management Unit.

From 9-12 a.m. on the appointed date, volunteers are paired up and stationed at 26 vantage points throughout the Tahoe basin, mostly around the lakeshore. A map of the stations can be found by clicking HERE. The eagle-counters tally and age any eagles they happen to see, and in recent years we usually get around 15; in 2014 and 2015 we have had over 20 different eagles during the count.  This year's count is scheduled for Friday, January 8th, 2015.
