If you think pretty things can't be poisonous, then I hope for your sake you live somehwere with very harmless flora and fauna. In fact, animals sometimes have strong colors as "warnings" to signal that they don't need to be camflauged, becasue they are poisonous. I dunno if this goes for plants as well, but I do know that aesthetic appeal is not necessarily correlated with safe edibility. Though, given the effect of the night howler it's probably not a poison evolved for defense, its effects in animals are probably just a side-effect of some more sensible purpuse the substance has in the actual plant.
