Callocephalon fimbriatum

As I walked up the track, I heard gang gangs making a bit of a racket not too far away. Taking a deviation from my quick leg-stretch, I looked up and to my surprise, discovered a new female fledgling (I'll call her Floss for the time being). She's not from any known hollow, and her mother, Stevie, has lost her right eye and is identifiable. In the tree next to Floss's family, chatting with all the others, was the family of two new male fledglings (sighting 4638428). Floss's Dad fed her twice, then mum and dad intensely allopreened her for some time. Dad flew off, and two minutes later mum also left. I wondered - were they looking after another fledgling at their mystery hollow? Or were they feeding (there were a number of gang gang feeding on various street trees at the time)? Meanwhile, Floss stayed put on her twig, playing with biting off leaves, balancing awkwardly, moving up and down a twig or very thin branch. After half an hour or so, dad returned, flew at Floss and squawked, which frightened her to fly a short distance to another twig. Dad stayed a short distance away, and they just fell silent and still. I left, after being there a couple of hours. By this stage dad had been there for about an hour, and was still resting. Two hours later I returned (I really wanted to find that hollow - and the other other fledgling, if there was one!) Dad was there in the same place, resting (unknown if mum had relieved him in the intervening hours). Floss was also resting, chewing her feet, moving a bit more confidently. Tom T arrived, and we looked at potential nest trees that I'd identified earlier - but there were no soft growls, no gang gangs in sight. I stayed another couple of hours, and Tom took over the observing. At 5.30, Tom called - mum and dad were both back with Floss. I was there in a jiffy! Two other pair of gang gangs arrived, talked and squawked, and suddenly Floss looked like she fell out of the tree - but she gathered herself, flying low, and onto a branch across the path, parents following. Now she'd gained her wings she was off again, landing on a thick bough but unable to balance, falling off and then swooping between the trees, to finally land in a thin-branched suckling. There she stayed for the next couple of hours, chewing small nuts, biting off leaves, stretching her wings, hanging upside down, losing her balance and recovering her balance. All in silence. Mum and dad returned around 7.30 and the three flew to a nearby copse of bigger trees, with Floss more confident in her flying and landing skills. She was fed, and the three of them took off for the night. Their nesting site remains a mystery - and so much for my short walk, and my plans for the day . . .!
