棕背伯劳两种色型繁殖特征的比较

Comparison of Breeding Ecology Between Two Color Morphs of Lanius schach

  • 摘要: 棕背伯劳(Lanius schach)具羽色多态现象,其中黑色型是否为独立种曾存在着争议。为此,于2008年2—6月在广东海丰地区对两色型(棕色型和黑色型)的繁殖生态进行对比研究,以探讨黑色型的分类地位。结果表明:1) 两色型伯劳窝卵数、卵的度量值及发育上皆无显著差异(P>0.05);2) 两色型雏鸟在15日龄前的体长、翼长及体重等生长曲线均符合Logistic方程,除尾长渐进值参数呈显著差异(P<0.05)外,其他均无显著性差异(P>0.05);3) 据14日龄的雏鸟测量值表明,两色型在身体外部器官各项生长量度均无显著性差异(P>0.05) 

    Abstract: Lanius schach is typical of species with color polymorphism. The black morph has been regarded as an independent species by some authors. We compared the breeding ecology of the black morph and brown morph of L. schach to explore the classification position of the black morph. From February to June in 2008, observations were made on the breeding ecology of the two morphs. Trials, including of interchanging their eggs and nestlings, were carried out in Haifeng Natural Reserve, Guangdong Province, China. Logistic equations were used to describe growth of the body morphological characters of the nestlings. The results showed: 1) There were no significant differences of egg figures between two types (P>0.05). 2) The growth of the body mass, wing length and other morphological characters of >15-day-old nestlings could be described accurately by the Logistic equation. 3) There were no significant difference between the body morphological characters of the 14-day-old nestlings,but there was significant difference on the asymptotic value of the ninth primary. 4) The experiments of interchanging eggs and nestlings showed that during the process of sitting and fostering, eggs and nestlings of the same period from the two color morphs were accepted, but eggs of different periods were rejected. 5) Nestling behaviors did not differ between the nestlings from different patterns. We concluded that black morph is not an independent species but a color morph of L. schach.
