小杜鹃

我在多年以前的A区有记录过一笔鸣唱的小杜鹃。

I have one record of singing Lesser Cuckoo from Area A in late May many years ago .

这个月到现在个人已有好几次小杜鹃的记录了。

I have recorded Lesser Cuckoo in Chi Gu several times between now and the end of the month .

过去几年的五月中旬，个人常在七股记录到小杜鹃，有几次还在鸣唱。

In previous years , I have seen Lesser Cuckoos in Chi Gu in mid May .

在小杜鹃的赤色型雌鸟，腰部和背部的界线很明显，并且形成强烈对比。

On hepatic female , the border between the rump and mantle is obvious , forming a strongly demarcated contrast ( there is a line ) .

我以前看过赤色型的小杜鹃雌鸟，这种色型的很好辨识，它有很明亮的橙色和没有纹路的头顶及腰部。

I have seen hepatic female Lesser Cuckoo before , and Lesser is obvious in this plumage , having a bright orange and unmarked crown and rump .

假设非赤色型的小杜鹃也会出现这样的对比：暗色的腰部（与尾羽不形成对比）和比较淡色的上背部。

Presumed non-hepatic morph adult Lesser Cuckoos have shown this same contrast , between a very dark rump ( which does not contrast with the tail ) and a paler upper back .
