觀察細節
Two terns flying over the pocket pond and fishing. They were about the size of Forster terns. The bills appeared predominately dark. The black on the head started at the eye and wrapped around the back of the head. Front forehead was white. They were making this subtle chirp while foraging. It appeared to be a contact call of sorts for the birds to communicate while flying around and feeding.
