Took a video of this bird nesting. Photo are screenshots from vid. Sorry for pour quality
unfortunately the only photo of this one
Photos show a tern. We did see it a little closer and are confident of an Australian tern. Big white tern. Not a marsh tern. Most likely candidate. You can just make out the black on the face.
either little or long-billed corellas; looking at the outline of the beaks, I'm thinking maybe long-billed?
Picture sucks, birds are too small for my phone Cam. Tiny little finch like birds. Brown/grey in colour on top, with off white underside. Tail comes to kind of a black point. Looks to have a black banding around face. Tiny in size like 1/2 to 1/4 the size of a Willi way tail
