本项目以我国北热带地区典型的石灰岩森林鸟类为研究对象，探讨它们对岩溶生态系统的特有繁殖策略。由于北热带地区丰富的水热条件和较高的巢捕食压力，鸟类在繁殖期间可能至少采取3种不同于其它生态系统的生活史对策。项目主要研究在岩石上筑巢鸟类的繁殖行为、巢址选择、窝卵数、孵卵节律、幼鸟发育和巢捕食等，利用野外观察和人工模拟实验的方法，结合当地气象数据和食物丰富度变化资料进行分析，揭示北热带地区石灰岩森林鸟类的特有繁殖规律，阐明它们的独特繁殖适应机制。通过了解鸟类对岩溶生态系统的繁殖适应策略，可以帮助探讨鸟类对这一特殊生态系统的适应和演化过程，同时也可为我国北热带石灰岩森林的鸟类和生物多样性保护提供科学依据。

The purpose of this project is to discuss the peculiar breeding strategy of bird in limestone forest, north tropic area of southern China. Because of abundant rainfall and sunshine, high nest predation in tropical limestone forest, we predict the bird maybe use 3 different breeding strategy from the other ecosystem of China. We would study the breeding behavior, nest site selection, clutch size, incubation rhythm, nestling development and nest predation of birds nested on the rock. Field observation and artificial nest are used to study the breeding strategy of birds. However, meteorological data and food availability is helped to confirm the hypothesis of life history in north tropical limestone forest. It will help realize the adaption and evolution of birds in limestone by means of breeding strategy study. Meanwhile, it will also supply the initial data for the conservation of bird and other animals in limestone forest, north tropic of southern China.
