摘要通过口服吐酒石的强制反流已被频繁地用于检查鸟类饮食，因为它不需要直接杀死鸟类，但通过这种技术的间接（延迟）死亡率没有得到很好的研究。我们研究了吐酒石在非繁殖季节在牙买加的食虫迁徙鸣禽的再目击率的影响。用吐酒石处理的黑喉蓝莺（Dendroica caerulescens）的再目击率显着低于对照鸟。用吐酒石处理的美洲红尾莺（Setophaga ruticilla）、黑白白色莺（Mniotilta varia）和草原莺（Dendroica discolor）的再目击率也低于那些被捆绑并未经处理释放的鸟类。释放前的死亡率较低（<3%），但在释放后22小时内发现两只经处理的黑喉蓝莺死亡。我们的研究结果表明，应用吐酒石是一种有效的，但侵入性的方法，从鸟类的饮食样品收集。研究人员应考虑替代品，未来的吐酒石管理应保守进行，并承认其偶尔致命的结果。
Abstract Forced regurgitation by oral administration of tartar emetic has been used frequently to examine avian diets because it does not require killing birds directly, but indirect (delayed) mortality by this technique is not well studied. We examined the effects of tartar emetic on re-sighting rates of insectivorous migratory songbirds in Jamaica during the non-breeding season. The re-sighting rate of Black-throated Blue Warblers (Dendroica caerulescens) experimentally treated with tartar emetic was significantly lower than for control birds. The re-sighting rates of American Redstarts (Setophaga ruticilla), Black-and-white Warblers (Mniotilta varia), and Prairie Warblers (Dendroica discolor) treated with tartar emetic were also lower than those of birds that were banded and released without treatment. Pre-release mortality rates were low (<3%), but two treated Black-throated Blue Warblers were found dead up to 22 h after release. Our results suggest application of tartar emetic is an effective but invasive method for collecting diet samples from birds. Researchers should consider alternatives, and future administration of tartar emetic should be conducted conservatively and with acknowledgment of its occasionally lethal results.
