Molt Migration by Giant Canada Geese in Eastern South Dakota
We captured giant Canada geese (Branta canadensis maxima) in 7 counties in eastern South Dakota during the summer molting period, 2000–2003. We attached very high frequency (VHF) transmitters to 150 adult female geese with brood patches, and leg bands to 3,839 geese. We documented molt migrations us...
