摘　　要：在鸟类巢寄生行为中,寄主和宿主之间的共进化主要体现在鸟卵的颜色和斑纹上.宿主通过增强对寄生卵的识别能力,来降低和抵抗被寄生的代价.模型卵常被广泛用于验证和测试宿主对外来寄生卵的识别能力.文章介绍了模型卵在鸟类巢寄生行为研究中的应用,以实例详述了模型卵的制备方法,并通过光纤光谱仪对模型卵的模拟程度进行测量和调整.本方法制作的模型卵,制作材料简单且容易获得,硬度合适,不容易变形但又可以被宿主鸟啄破和叼走;本方法可针对不同研究的需要,根据宿主卵的大小和重量来制作,并涂以不同的颜色和斑纹来制作.Avian brood parasitism sets a unique stage for investigating co-evolution, as egg coloration is the main trait under selection in both parasites and hosts. Model egg was used to test egg recognition in various hosts. However, some hosts could not peck and reject the non-mimetic model egg due to some conditions and constraints, even they might recognize it. These influencing factors were analyzed and then research advices were put forward to improve and standardize the model egg and its application. In particular, fiber spectrophotometer was used to quantitatively analyze the egg reflectance spectra of the used model egg.
