Temperate-breeding, or resident, Canada geese were once extirpated in Kansas, USA, but currently provide abundant viewing and hunting opportunities. Kansas Department of Wildlife, Parks, and Tourism (KDWPT) began reintroducing geese in 1980 with a goal of re-establishing a breeding population. Successful reintroductions led to translocating flocks to regions with no previous records of nesting geese; however, KDWPT continues to translocate individuals from nuisance flocks in urban areas to rural reservoirs to reduce human conflicts with urban geese. Our goal was to determine the effects of such translocations on survival and recovery of adult, sub-adult, and juvenile temperate-breeding Canada geese. We used Brownie dead-recovery models in Program MARK to compare survival and recovery probabilities between translocated and nontranslocated (normal wild) Kansas-banded Canada geese for 2012–2017. Model-estimated annual survival differed between status (normal wild = 0.761, 95% CI 0.734–0.785; translocated = 0.598, 95% CI 0.528–0.665). Recovery probability differed between normal and translocated adults (normal wild = 0.074, 95% CI = 0.069–0.078; translocated = 0.138, 95% CI = 0.120–0.158) and juveniles (normal wild = 0.067, 95% CI = 0.059–0.075; translocated = 0.250, 95% CI = 0.199–0.310). Recovery probability did not differ between status in the sub-adult age class (normal wild = 0.126, 95% CI = 0.115–0.137; translocated = 0.090, 95% CI = 0.055–0.144). Translocation is a viable management option to successfully reduce survival and increase recovery probability of urban nuisance geese in Kansas.

堪萨斯条纹加拿大鹅的易位、存活和恢复
温带繁殖或居民加拿大鹅曾经在美国堪萨斯州灭绝，但目前提供了丰富的观赏和狩猎机会。堪萨斯州野生动物、公园和旅游部 (KDWPT) 于 1980 年开始重新引入鹅，目标是重新建立繁殖种群。成功的重新引入导致鹅群转移到以前没有筑巢鹅记录的地区；然而，KDWPT 继续将个体从城市地区的滋扰群转移到农村水库，以减少人类与城市鹅的冲突。我们的目标是确定这种易位对成年、亚成年和幼年温带繁殖加拿大鹅的生存和恢复的影响。我们在 Program MARK 中使用布朗尼死亡恢复模型来比较 2012-2017 年易位和非易位（正常野生）堪萨斯带状加拿大鹅的存活和恢复概率。模型估计的年生存率因状态（正常野生 = 0.761，95% CI 0.734–0.785；易位 = 0.598, 95% CI 0.528–0.665)。正常和易位成虫的恢复概率不同（正常野生 = 0.074，95% CI = 0.069–0.078；易位 = 0.138, 95% CI = 0.120–0.158) 和幼鱼（正常野生 = 0.067，95% CI = 0.059–0.075；易位 = 0.250，95% CI = 0.199–0.310）。恢复概率在亚成人年龄组（正常野生 = 0.126，95% CI = 0.115–0.137；易位 = 0.090，95% CI = 0.055–0.144）。易地是一种可行的管理选择，可以成功降低堪萨斯州城市滋扰鹅的存活率并增加其恢复概率。
