Tis a Bird of prey you seek to locate but not at this location. You are going to have to solve the puzzle to get the coordinates that will allow you to visit this cache which is located in an interesting section of bushland. However if other activities are underway, walk away and come back at another time.
I might move silently across the night sky and search for prey by using my extra strong eye sight and hearing to show me a suitable target. Once located, I have to move swiftly into attack and capture . Most marsupials and some reptiles are suitable prey but Possums are my favourite.
Every day I wake the humans from their sleep with my extra strong amazing song. Sung at dawn it is very distintive. I am very family orientated and all older sibling help with feeding and protecting younger hatchlings until it's time move away to begin their own family in another district. I love to find dangerous reptiles and show humans how to treat them.
I might fly across Port Hacking in search of a feed of fish and spy on some numbers that identify man built structures along the waterfront. While I am not seeking smaller birds as prey, my size and dominance makes me a target out of fear and if I choose to take a rest on one of the many metal limbs that humans make available to me to look for the next elusive meal, I am attacked by them. Don't drop your catch, it will swim away quickly and unless you can dive, it will be lost forever.
