We analyzed banding and recovery data for Canada geese (Branta canadensis) banded in Nebraska during 1990–2000. Survival rates were lower during 1996–2000 (adult: 0.688, SE = 0.016; juvenile: 0.611, SE = 0.029), than 1990–1995 (adult: 0.727, SE = 0.011; juvenile: 0.639, SE = 0.024). Average juvenile-to-adult ratio from banding data was 0.834 (SD = 0.485), resulting in an annual population growth rate (λ) estimate for 1990–1995 of 0.995 (95% CI = 0.021), and 0.922 (0.018) for 1996–2000. Our recovery analysis suggests that 67% of geese banded in Nebraska are shot in Nebraska. Over 30% of both juvenile and adult recoveries …

Urban Canada Geese In Georgia: Assessing A Golf Course Survey And A Nuisance Relocation Program, Larkin A. Powell, Michael J. Conroy, Kipling S. Balkcom, Joe Caudell

Nuisance complaints about Canada geese (Branta canadensis), have risen in recent years. In Georgia, managers have responded by relocating some nuisance geese to rural areas. During 1993–1996, we used band recoveries of relocated geese to determine the efficacy of relocation as a management strategy. We also used data from a post-card survey of golf courses to monitor the urban subpopulation of Canada geese in Georgia during 1998–2001. Flocks considered by golf course superintendents to be a nuisance were larger (1998: 48.8 geese, 1999: 71.5, 2000: 73.2, 2001: 67.2) than nonnuisance flocks (1998: 13.1 geese, 1999: 16.7, 2000: 25.8, 2001: 18.1). …
