Hmm, well, I can keep myself entertained with very limited supplies (example: I wove my boss a crown out of ticket stubs over several slow days at work), but I'd still want my pencil case/sketchbook. Since other people've taken care of the cutting and tying things, I'd also want a comprehensive illustrated encyclopedia of tropical flora/fauna. Hopefully this would keep the trial and error aspect of figuring out what to eat and/or run away from to a minimum.
There's a rule of thumb for food: if you see a monkey or ape eating something, you can probably
eat it. Birds, however, are not good guides to edibility, because there are substances which will poison mammals which birds can eat safely (forex, like reptiles, birds are immune to capsaicin. Artifical grape flavor, on the other hand . . .)
For running away, my rule is that if it's bigger than me, or has sharper teeth than me, or has its babies with it, I avoid it.
