At the first tree where I saw the Gang-gangs and the Sulphur-crested Cockatoo I was sure I could hear a Striated Pardalote, I really wanted to take a photograph of it so I moved closer to the tree. I saw a bird hopping along a branch, positive I had found my subject. I saw it had travelled to the end of the branch but then it disappeared. I could not look further as I was distracted then by the Gang-gang. A little while later I noticed a hole under the branch, which sure enough, a pardalote turned up to. It appeared to be chipping away at it. I could hear noise like chipping and it spent a lot of time at the entrance. The hole may have been larger inside as the bird entered head-first but exited head-first as well. It spent most of its time around the edge of the hole. I saw at least two pardalotes in the tree but only ever one near the hole.
