A small group of ten members and friends met at Uriarra Homestead at 5.00pm, in advance of our night time foray into the Brindabellas. We stopped near the top of the range at Picadilly Circus, for Jenny to play back all the calls of the birds we were about to hear. We divided into three vehicles, and agreed to meet at the end of Walks Road at about 9.00pm. The night 
was drawing in fast when the atlassing commenced at about 6.00pm. One vehicle atlassed along Two Sticks Road toward Mt Coree and on the road to Brindabella beyond Picadilly Circus, another trundled along the top of the range on Mt Franklin Road and the third vehicle visited Bendora Dam and Walks Road. It was a mostly clear evening, that became quite cold.
We atlassed here. We atlassed there. We atlassed high. We atlassed low. Between the three atlassing crews we heard a single owlet-nightjar call once. Our conclusion is! that in July, the Boobook Owls and similar do not call. Two of the crews spied a Greater Glider each. It was disappointing, but it still resulted in data for the atlas - a number of nil-return data sheets. It is important that if atlassing, that nil returns be passed in, because it is a representation of what is not there, as much as a record of that which is there. We look forward to a more successful night-atlas in November
