| 摘 要： | 于2009年4—7月,采用光谱仪量化卵色和建立鸟类视觉模型的方法,在贵州宽阔水自然保护区对中杜鹃(Cuculus saturatus)寄生冠纹柳莺(Phylloscopus reguloides)的卵色模拟进行了研究。中杜鹃产白色卵带极少数而微小的棕色斑,明显大于宿主卵,重2.06g,体积1.91cm3。从人眼看,中杜鹃卵对宿主卵在很大程度上是模拟的,但视觉模型表明,两者的卵色在色调和色度上都完全分离,揭示了人眼探测不到的卵色模拟情况。该文首次对中杜鹃的雏鸟特征进行描述,在4日龄以后雏鸟嘴裂中出现三角形黑斑,并随着日龄的增长而更加明显,这种特征在霍氏中杜鹃(C.optatus)的雏鸟中也存在,但未见于其他种类的杜鹃雏鸟。

| Abstract: | Brood parasitism and egg mimicry of Himalayan Cuckoo(Cuculus saturatus) on its host Blyth's Leaf Warbler(Phylloscopus reguloides) were studied in south-western China from April to July 2009.The cuckoo laid a white egg with fine brown markings on the blunt end.The eggs were conspicuously bigger than the host's own,with 2.06 g in mass and 1.91 cm3 in volume.Visual modeling showed that the cuckoo eggs,which from the human eye appeared to mimic the host eggs to a great extent,were completely different from the ... |
