Abstract:

Female Barrow's Goldeneye (Bucephala islandica) return to the same breeding area every year and often use the same nesting sites. Males accompany their mates from wintering areas, defend territories on the breeding ground, and then leave for unknown molting areas when the female is incubating. They are not seen again on the breeding ponds until the following spring. I present evidence here indicating that some Barrow's Goldeneye pairs remain intact from year to year in spite of a long separation and that pair reunion occurs on the wintering areas.
