Black Noddy (Anous minutus) ヒメクロアジサシ
Black Noddies are very similar to Brown Noddies. The Black Noddies are supposed to be darker black with more distinct white caps. The Black Noddies from the main Hawaiian Islands (Anous minutus melanogenys) are supposed to have lighter heads and tails and yellow feet. I think that there may be a mix of Hawaiian Black Noddies and Black Noddies in these pictures. There could be some Brown Noddies too. Kauai 2014
