将6种不同颜色的人工卵和对照卵引入到灌木林莺、小杜鹃和喜马拉雅杜鹃的巢中。日本的saturatus。接受所有对照（巧克力棕色）和人造红色鸡蛋;拒绝所有灰色和所有白色鸡蛋。灰卵上橙子、粉红色和橙子斑点的排斥率分别为8%、36%和55%。丛林莺更有可能拒绝鸡蛋，因为它们与自己的鸡蛋越不一样。研究结果加强了小杜鹃和喜马拉雅杜鹃的巧克力棕色蛋可能是通过布什莺的辨别能力和对不同蛋的不容忍而进化的。
Artificial eggs of six different colours and control eggs of Bush Warblers Cettia diphone were introduced into nests of Bush Warblers, a host of both Little and Himalayan Cuckoos Cuculus poliocephalus and C. saturatus in Japan. All control (chocolate-brown) and artificial red eggs were accepted; all grey and all white eggs were rejected. The rejection rates of orange, pink and orange spots on grey eggs were 8%, 36% and 55%, respectively. Bush Warblers are more likely to reject eggs the more dissimilar they are from their own. The results strengthen the possibility the chocolate-brown eggs of Little and Himalayan Cuckoos may have evolved through the discriminative ability of Bush Warblers and their intolerance towards dissimilar eggs.
