大鸥 meaning in Chinese

The big gulls are early migrants , and some should be moving north now
这些大鸥是较早迁徙的候鸟,其中一些现在应该正在北返
In the mid - winter period , a pale - mantled gull with an entirely white head really has to be mongolian
在冬季中期，我们可以判断一只背羽淡色而头部全白的大鸥一定是蒙古银鸥。
I would expect , though , that mongolian gull would be a big number migrant through that area and that your big gulls would be that species
我会认为,蒙古银鸥会大量的迁徙经过该区域,而你的大鸥会是那个鸟种
