摘要
四川长尾鹅有长尾和短尾两种体态.其雄鸟还有白色和棕色两种类型.两类雄鸟无年龄上的先后之别,应为遗传多态.
This Paper checked 64 specimens of paradise flycatcher collected from the province of Sichuan. These specimens indicate that two outward forms, long-tailed and short-tailed, in both sexes and there are two color phase, white and rufous, in males. A series of intermediate individuals occur between long-tailed and short-tailed males without respect to any color phase. So we think of this phenomenon as polymorphism. From our observation, the age transformation of the Sichuan paradise flycatcher, as it were, can be shown in brief as follows.Female: rufous short-tailed form-Hong-tailed form.Male: rufous short-tailed form that is more purple than femaleswhite short-tailed form-long-tailed form.(The crest is long-drawn distinctly, whole head and neck are metallic-blue black) rufous short-tailed form-long-tailed form.
