了解和描述影响鸟类繁殖扩散的因素对于建立种群动态模型和设计保护策略至关重要。本文利用1998-2003年在南加州筑巢的穴鸮(Athene culcularia, Molina, 1782)的波段观测数据,研究了穴鸮的扩散概率和扩散距离受筑巢成功和配偶忠诚度的影响。大多数猫头鹰(253只中的167只,占66%)仍停留在初始巢附近(分布距离为100 m(472±65 m)(平均±1 SE; n = 86)。无论是雌猫头鹰还是雄猫头鹰,巢巢失败的猫头鹰都比巢巢成功的猫头鹰更容易分散,而且分散的距离更远。失败的筑巢尝试也与离婚的可能性增加有关,离婚与分散概率和距离的增加有关。此外,雌性和雄性猫头鹰更有可能在配偶死亡后分散,并且比那些仍然活着的猫头鹰分散得更远。
Understanding and describing the factors that affect avian breeding dispersal are critical for modeling population dynamics and designing conservation strategies. We investigated the hypothesis that dispersal probability and dispersal distance are affected by nesting success and mate fidelity with band–resight data (1998–2003) from burrowing owls (Athene cunicularia (Molina, 1782)) nesting in southern California. Most owls (167 of 253, 66%) remained near their initial nest ( 100 m dispersed 472 ± 65 m (mean ± 1 SE; n = 86). Both female and male owls whose nests failed were more likely to disperse and dispersed longer distances than owls with successful nests. Failed nesting attempts were also associated with an increased probability of divorce, and divorce was related to increased dispersal probabilities and distances. Moreover, female and male owls tended to be more likely to disperse and to disperse greater distances following the death of a mate than those that remained pa...
