IT ALL STARTED the night I stood under a balsa tree in central Panama, struggling to get a good look at the animals running around in the branches above me. If it wasn't for them, I would never have become a tropical biologist. Occasionally I glimpsed the mysterious arboreal acrobats through gaps in the leaves, but I was having trouble co-ordinating my spotlight and binoculars on such agile targets. Finally, one of the critters stayed still long enough for me to catch it both in my beam and in focus.
