Telemetry Maps for Juvenile Bald Eagles
Using satellite telemetry transmitters, we have studied the natal (first summer) migrations and movements of bald eagles that fledge from nests in California. Three of the four youngsters traveled to British Columbia in their first and subsequent summers after returning to California in fall and winter. A fourth made yearly migrations to Canada's Great Slave Lake, much like the wintering eagles we have studied.

Shasta Juvenile Male #1
Fall 1997: Northward dispersal, toward salmon runs, from natal site of a fledgling male bald eagle tagged at Shasta Lake in summer of 1997, and his eventual "destination".
Spring 1998: Fall/winter return trip to California of a fledgling male bald eagle tagged at Shasta Lake in summer of 1997. This bird was filmed by an associate during his return trip, above a sandbar covered with spawned out salmon, in the company of 100+ other bald eagles. He is currently (April 24, 1999) back near his natal area at Shasta Lake.
Shasta Juvenile Male #2
1998-1999: Northward dispersal, toward salmon runs, from natal site of a fledgling male bald eagle tagged at Shasta Lake in summer of 1998. Transmitter was functioning daily during his northward journey, giving a detailed look at distances traveled.
Shasta Juvenile Female #1
1998-2000: Northward dispersal, toward salmon runs, from natal site of a fledgling female bald eagle tagged at Shasta Lake in summer of 1998, and her most recent 1999 locations. The transmitter was functioning daily during her northward journey, giving a detailed look at distances traveled.
"Baby Huey" - Shasta Juvenile Female #2
1998-1999: Last year’s Shasta Lake fledgling begins her second trip southward from the Great Slave Lake in Canada’s Northwest Territories to her natal state of California.
1999-2000: Last year's Shasta Lake fledgling begins her second trip southward from the Great Slave Lake in Canada's Northwest Territories to her natal state of California.
