Let's see the comments from the more experienced birders. Logged kwan pelican BBS Member BBS Junior Member I love bird watching!     Gender: Posts: 15 Re: 請問這是甚麼鷗?

I agree with what KWAN said!Since Common Tern seens to have a longer and deeper folk tail. Besides, Common Tern mostly found in Hongkong, its bill and legs are black in color.   And I think that it was possibly a juenvile bird as you can find some dot on its back or even on its wings .Dots are rare and more separate in Whiskered Tern rather than White-winged Black Tern. Therefore, Whiskered Tern will be the answer!   That's only my option!! If there is any things wrong, pls let us know!!! « Last Edit: Nov 5th, 2002, 8:46am by Forrest FONG » Logged 648 BBS Member BBS God     Posts: 439 Re: 請問這是甚麼鷗?
