I read this fact, about elephants hating chili, from @cryotosensei and started to wonder if there is any animal that do not hate chili other than humans? I mean, don't they all hate chili? At least, that was my original thought...
I turned to the almighty internet and found the following:
THE ONLY OTHER animal known to seek out the heat of capsaicin – the active component of chilis – is the treeshrew, a tiny mammal found in the tropical forests of Southeast Asia.
Oh, and they also don't get drunk.
Birds don't hate chili. Indeed, chili fruits have evolved to be attractive to birds so as to have their seeds widely dispersed by them after passage (unchewed, as birds don't have teeth) through the bird's gut. At the same time, chili fruits have evolved to be unattractive to most mammals by incorporating capsaicin which 'burns' (irritates) mammals but has no effect on birds.
