Résumé :	Satellite telemetry was used to identify migration routes and stopovers, estimate migration chronology, and describe variation in movements among American Black Duck Anas rubripes marked in Delaware, New Jersey, New York, Ohio and Virginia between 2007-2009. Thirty-one transmitters each provided data for at least one spring migration. The ducks departed their wintering areas during 18 March-7 June ((x) over bar +/- s.e. = 17 April +/- 3.3 days), averaged 3.35 +/- 0.3 stopovers (range = 1-5 stopovers) and spent 6.44 +/- 0.8 days at stopover sites (range = 0.54-12.2 days), migrated 1,126.1 +/- 89.5 km (range = 270-1,396 km), and arrived at inferred nesting areas during 16 April-28 June ((x) over bar = 9 May +/- 3.4 days). Black Duck on the South Atlantic Flyway migrated nearly twice as far (P
