And whenever we were doing seet call playbacks to the yellow warblers, the red-winged blackbirds kept showing up.

只要我们给黄莺播放seet叫声，红翅黑鹂就会出现。

And they respond to the seet calls the same way they do to the sounds of cowbirds themselves.

听到seet叫声后，它们的反应与听到棕头牛鹂叫声时一样。

Yellow warblers, for example, produce a certain type of call to warn other warblers about nearby cowbirds. Researchers call it a " seet" call.

比如，黄莺会发出某种叫声，提醒同类周围有棕头牛鹂。研究人员称之为“see”叫声。
