Bald Eagle Research

Satellite Telemetry Studies

Grainger Hunt, Ron Jackman, Janet Linthicum and Brian Walton are involved in studying the international movements and local ecology of bald eagles originating in or visiting California in cooperation with the US Forest Service, the California Department of Parks and Recreation, and the California Department of Water and Power.

This amazing technology allows us a remote glimpse into the long-term movements of bald eagles across the North American Continent, information that could never be garnered in any other way.  We appreciate the cooperation of the California Department of Water Resources, the California Department of State Parks and Recreation, and the US Forest Service for their part in these studies.

The goal of this research is to use this powerful technology to shed a vastly brighter light on the origin of both wintering and native bald eagles in California, their patterns of movement, and the factors influencing habitat use and life history.

Bald Eagle Mid-Winter Survey:

In recent years, SCPBRG has been coordinating the long-term California Midwinter Bald Eagle Survey.  Survey results for 2004 and 2005 are now available.
