In-situ captive rearing of endangered passerines for reintroduction has rarely been used as a conservation tool. Nests of Mauritius fodies threatened with predation by introduced mammalian predators were harvested from the wild, and chicks were reared to independence for release onto an offshore, predator-free island. The daily probability of the survival was higher in captivity than in the wild, and 69 chicks were reared to fledging of which 47 would have been expected to fledge in the wild. Harvesting of nests probably had little impact on the wild population. Captive breeding trials on Mauritius fodies showed that large numbers of individuals could be produced for a release program from a small number of pairs if enough space was provided. Artificial incubation of passerine eggs and rearing of chicks can be used to increase the productivity of endangered taxa. Zoos can play an important role in in-situ conservation programs through provision of avicultural expertise and training of local staff. Zoo Biol 27:255-268, 2008. (c) 2008 Wiley-Liss, Inc.
将濒危雀形目鸟类进行圈养繁殖以用于放归，这种方式很少被用作一种保护手段。受到外来哺乳动物捕食者威胁的毛里求斯拟黄鹂的巢穴从野外采集而来，雏鸟被饲养至独立，以便放归到一个离岸的、没有捕食者的岛屿上。圈养中雏鸟每日的存活概率高于野外，69只雏鸟被饲养至羽翼丰满，而预计在野外只有47只雏鸟能够成功出飞。采集巢穴可能对野生种群影响很小。对毛里求斯拟黄鹂的圈养繁殖试验表明，如果提供足够的空间，少量配对的个体就能为放归计划产出大量个体。对雀形目鸟类的卵进行人工孵化和饲养雏鸟可用于提高濒危类群的繁殖力。动物园可以通过提供鸟类饲养专业知识和培训当地工作人员，在原地保护计划中发挥重要作用。《动物园生物学》27:255 - 268, 2008年。(c) 2008威利 - 利斯公司。
