鸥科

一般在网路上鸥科辨识似乎都是讨论一大群聚在一起的鸥鸟间的形态差异。

Identifications ( on the web ) often seem to be made on their respective structural differences when large numbers of gulls are gathered together .

再次提起，我建议有兴趣的鸟友参考那本“鸥书”和前此提到的“日本鸥科网站”，可先不管其他的图鉴，大部分通用性的图鉴对鸥科的辨识都不太重视。

Again , I suggest people consult the " gulls book " and " Japanese Gull Site " rather than anywhere else , most " general " field guides pay very little attention to gulls .
