This information allowed me to conclude that they would be found by water-sources; rivers, streams and pools of water but as an arboreal species they would be slightly higher in the foliage during the day - absorbing sunlight in branches above, storing energy and digesting their previous nights meal rather than waiting to ambush prey lower to the ground.
Although it took several hours of meticulously scouring the bushes and trees besides a selected stream, we did eventually discover one poised just above head-height below a clearing in the canopy above.
It was one of my happiest moments in wildlife photography - shooting a species that I'd read about and seen pictures of ever since I was a young boy. A dream come true.
If I hadn't spent the time researching my subject, learning it's behaviour and understanding the animal more intimately then chances are I wouldn't have seen one. Although there are always the 'coincidental' moments in photography where you just happen to be in the right place at the right time - this isn't something that can be relied on, and even less so if you are setting out with a particular species in mind or have been commission to photograph a particular animal.
Dedicate a little time to research before your next wildlife photography trip and I promise you, it will almost certainly pay-off.
