YOUNG BIRDER'S NOTES: Birding in the Canberra Botanic Gardens

I have just returned from a trip to the Australian capital city, Canberra. While this was mostly a sightseeing trip, I managed to fit in a bit of birding with my father into the trip. So, at about 9.33 am, my dad, my mum, my sister and I travelled to the Australian National Botanic Gardens, to try and spot the gang-gang cockatoo, a bird that was apparently common there.
First we walked up to the Visitor Center and from there we headed to the Cafe. The air was thick with swarms of European Wasps. Among the wasps, on some rocks near a water feature, were 4 Gippsland Water Dragon lizards.

It looked rather like an adult wattlebird, but we could tell by its face that it was different. Though at first we thought it was a yellow-faced honeyeater, we realised it was just an immature wattlebird. We kept on walking and we decided to split up. Me and my mother went down the Main Track, while my father and sister would go along the Children's Discovery Walk, meeting back at the Cafe. We walked along the thick path, stopping to look for birds. We managed to spot a white-throated treecreeper, a magpie, two grey currawongs, an eastern spinebill, one pied currawong and lots of New Holland honeyeaters, as well as 2 kangaroos.

Though these were nice birds, we hadn't got the bird we were after- the gang-gang. Just then, we heard some sort of cockatoo call from a tree. It sounded different to the call of any cockatoo I had heard. We looked up into a nearby eucalyptus and . . .
