This autumn seems to be pretty good for Common Tern.  I am quite sure the group of 9 to 10 that we saw in early-August near Tern Island are Common.  Although Common does not breed in HK, it does pass through in good numbers regularly.

普通燕鷗次級飛羽下有深色橫帶

重有粉紅燕鷗的嘴是否全紅

有錯請見諒

有好照片,可檢查尾尖與翼尖的相對位置,粉紅尾很長,尾尖在翼尖之後。
飛起時 Chunfai 的方法可以,但最簡單可能是檢查背部,普通燕鷗有明顯的白腰。
