摘要

。定量评价和监测增殖力对保护的成功至关重要。我们正式评估了两个西部穴居猫头鹰(Athene culcularia hypugaea)在马尼托巴省和不列颠哥伦比亚省的种群增加计划的成功，通过评估繁殖成虫的存活率，羽化成功率和羽化雏鸟的返回率。曼尼托巴省的提前启动计划在冬天从先前的圈养释放的巢穴中捕获孵化年(HY)猫头鹰。在人类看护下越冬后，HY猫头鹰作为第二年(SY)猫头鹰成对释放。不列颠哥伦比亚省有一个繁殖和释放计划，在那里猫头鹰在设施中繁殖;它们的后代在冬天被饲养，在春天配对并放生。这两个项目都会释放SY对在原地产卵的幼鸟，它们被称为“野生孵化的猫头鹰”。我们调查了与我们的成功度量相关的个体猫头鹰和发布地点特征。在曼尼托巴省，繁殖季节的平均存活率为81%，但没有调查的因素对其有显著影响

Evaluating captive-release strategies for the Western Burrowing Owl ( Athene cunicularia hypugaea )

. Quantitatively evaluating and monitoring augmentation efforts are critical for conservation success. We formally evaluated the success of two Western Burrowing Owl ( Athene cunicularia hypugaea ) population augmentation programs in Manitoba and British Columbia by assessing survival of breeding adults, fledging success, and return rates of fledglings. Manitoba’s head-starting program holds hatching year (HY) owls taken from the nests of previous captive-released pairs over winter. After being overwintered in human care, the HY owls are released in pairs as second year (SY) owls. British Columbia has a breeding and release program where owls are bred in facilities; their offspring are then held over winter, paired and soft-released in the spring. Both programs soft-release SY pairs that lay clutches in situ and young are referred to as “wild-hatched owls.” We investigated both individual owl and release site characteristics in relation to our success metrics. In Manitoba, breeding season survival averaged 81%, but no factors investigated had a significant effect on

期刊介绍： Avian Conservation and Ecology is an open-access, fully electronic scientific journal, sponsored by the Society of Canadian Ornithologists and Birds Canada. We publish papers that are scientifically rigorous and relevant to the bird conservation community in a cost-effective electronic approach that makes them freely available to scientists and the public in real-time. ACE is a fully indexed ISSN journal that welcomes contributions from scientists all over the world. While the name of the journal implies a publication niche of conservation AND ecology, we think the theme of conservation THROUGH ecology provides a better sense of our purpose. As such, we are particularly interested in contributions that use a scientifically sound and rigorous approach to the achievement of avian conservation as revealed through insights into ecological principles and processes. Papers are expected to fall along a continuum of pure conservation and management at one end to more pure ecology at the other but our emphasis will be on those contributions with direct relevance to conservation objectives.
