The Tahoe Institute for Natural Science held its annual midwinter bald eagle survey Friday.
The survey gives researchers a snapshot of the number of bald eagles in the Lake Tahoe area during peak season, said Co-Executive Director Will Richardson. Teams of volunteers at 24 locations around the Lake Tahoe shoreline and two stations at Fallen Leaf Lake conducted the survey from 9 a.m. to noon Friday.
By noting the exact time, general age of the bird (juvenile or adult) and direction of travel, researchers can get a reasonably accurate assessment of the number of eagles present, Richardson said. The data are given to the U.S. Army Corps of Engineers, which coordinates the bald eagle survey nationally.
