白翅浮鷗OR鬚浮鷗

A photo for your comparison, the bottom one is White-winged Tern (Juv) and the top one is Whiskered Tern (Juv).
下面的是白翅浮鷗 (幼鳥), 上面的是鬚浮鷗 (幼鳥)

剛才相上方的鬚浮鷗(幼鳥)的近照


I think you can pay attention on their size and the feather on their head to seperate those Juv. Tern.
你可留意白翅浮鷗 及 鬚浮鷗 頭上的羽毛及牠們的體型來辨別牠們的幼鳥.
