摘　　要：2015年4-8月,在贵州宽阔水国家级自然保护区,记录到1巢白腹短翅鸲（Hodgsonius phaenicuroides）被鹰鹃（Cuculus sparverioides）寄生,寄生率为1/16（n=16）。发现时白腹短翅鸲巢内有1枚白色的寄生卵和2枚蓝色的寄主卵,且卵已凉,疑为亲鸟弃巢。鹰鹃卵重6.09 g,卵大小20.20 mm×27.73 mm;两枚白腹短翅鸲的卵重分别为2.34 g和2.40 g,大小分别为20.05 mm×14.94 mm和19.95 mm×15.09 mm。鹰鹃的卵重量（6.09 g）和大小（27.73 mm×20.20 mm）均明显大于白腹短翅鸲的卵。卵色光谱测量结果表明,鹰鹃和白腹短翅鸲卵色的反射光谱图差别明显,鹰鹃卵在色度和色调上明显低于白腹短翅鸲,但卵色亮度却明显比白腹短翅鸲卵高,为典型的非模拟寄生卵。During the breeding season from April to August in 2015, one case of White-bellied Redstart （Hodgsonius phaenicuroides） parasitized by Large Hawk-cuckoo （Cuculus sparverioides） was observed in Kuankuoshui National Nature Reserve, Guizhou, southwestern of China, and the cuckoo parasitism rate was 1/16 （n = 16）. The parasitized nest, with one white Cuckoo′s egg and two Redstart′s eggs （Fig. 1）, was found to be deserted by the redstart host. The Large Hawk-cuckoo egg was 6.09 g in weight and 27.73 mm × 20.20 mm in size, and two host eggs were 2.34 g and 2.40 g in weight and 20.05 mm × 14.94 mm and 19.95 mm × 15.09 mm in size, they were much different in egg mass and egg size （Table 1）. Egg measurements by spectrophotometer showed that they were much difference in spectrogram. The Large Hawk-cuckoo egg was a typical non-mimetic parasitic egg because of its egg chroma and hude were much lower than those of White-bellied Redstart, however, higher in brilliance （Fig. 2）.
