Several studies using harness attachment or implants have reached divergent conclusions about potential negative effects of radio transmitters on waterfowl behavior and condition. Our objective was to determine whether radio neck collars affect pair bond,breeding success and behavior of greater snow geese (Chen caerulescens atlantica). A total of 230 females were fitted with radio neck collars during the 1995-1998 molting period on Bylot Island, Nunavut, and data were subsequently obtained for 159 birds. Radios were fixed on plastic neck collars with a 15-cm downward antenna for a total mass. Over the years (1995 to 1998), 36% (95% CI = 27-45) of the females were separated from their original male after 10 months resulting in an estimated divorce rate of 25% (95% CI = 12-37) when accounting for male mortality rate.
