On my way off The Spit tonight around 5 I looked up to the nest area from the entrance gate, with my binoculars, and could easily see two 'black shapes'. Perhaps they were two of the four chicks. They stayed pretty much in one place and no adult flew in or out. I watched from Unwin for about 5 minutes but other than small changes in shape and a little bit of motion, that was all I could see from so far away. Wonderful to know they are up there!
