Radio tracking via satellite was initiated to study the year-round movements
of Golden Eagles(Aquila chrysaetosc anadensis) breeding on the east coast of Hudson Bay,
Quebec. In June and August 1992, six Golden Eagles(five adults and one juvenile) were
marked, three of which completed their year-round movements. The eagles left their breeding
area in mid- to late October and migrated to known wintering areas in the eastern United
States. They used different routes but each followed the same general path during fall and
spring migrations which lasted between 26 and 40 days,and 25 and 51 days, respectively.
Eagles wintered from 93 to 135 days in areas located 1,650 to 3,000 km south of their
breeding territory. In spring 1993, satellite telemetry located the eagles in their former
breeding territory in late March, mid-April and early May. This study confirms previous
suggestion that some breeding Golden Eagles wintering in eastern United States come from
northern Quebec and describes the first successful tracking of the complete yearly migration
cycle of a bird of prey.
