高巢捕食经常在热带鸟类中发现，但缺乏热带石灰岩地区的数据。在中国南方的石灰岩喀斯特雨林中，有两种穗鹛在不同的季节在岩石洞穴中繁殖：濒危的弄岗穗鹛（Stachyris nonggangensis）在5月繁殖，像大多数鸟类一样，常见的条纹鹪鹩穗鹛（Napothera brevicaudata）在3月繁殖。我们测试的假设，巢捕食不同的筑巢期使用人工巢实验。我们使用的天然岩石洞穴，其距离不同的森林边缘，检查巢在不同的时间间隔和测量的特点腔的位置。我们发现巢捕食要高得多，5月（65的99巢）比3月（14的83）;捕食往往是较高的巢时，只访问一次，但没有其他因素显着影响的结果。在温暖的天气下，捕食率较高，而且蛋大多立即消失，但红外线巢摄像机没有发现捕食者，这表明蛇可能是重要的捕食者;需要进一步的研究来证实这一假设。我们的结论是，异常的筑巢期的条纹？画眉可能是一种策略，以逃避巢捕食。
High nest predation is often found in tropical birds, though data from tropical limestone regions are lacking. In a limestone karst rainforest of south China, two species of babblers breed in rock cavities in different seasonal periods: the endangered Nonggang Babbler (Stachyris nonggangensis) breeds in May, like most birds, and the common Streaked Wren Babbler (Napothera brevicaudata) breeds in March. We tested the hypothesis that nest predation varied by nesting period using an artificial nest experiment. We used natural rock cavities that varied in their distance to the forest edge, checked nests at different intervals and measured characteristics of cavity location. We found nest predation to be much higher in May (65 of 99 nests) than March (14 of 83); predation tended to be higher when nests were visited only once, but no other factor significantly influenced the result. The higher predation rate during warmer weather, and the fact that eggs disappeared mostly at once, yet predators were not detected on infrared nest cameras, suggests that snakes could be important predators; further research is needed to confirm this hypothesis. We conclude that the aberrant nesting period of the Streaked Wren Babbler may be a strategy to escape nest predation.
