Birds are not sensitive to capsaicin, the chemical that makes chillies
hot. Bird consumption of fruit and subsequent dispersal of seeds is
importnat to wild chillies. All mammals tested have been found to
be sensitive to capsaicin (anyone noticed marsupials grazing on their
chillis?). This deters their consumption of the chilli's fruit which may
be beneficial to the chilli if mammals would be ineffective dispersers of
the seed. This could be the case if mammals travelled shorter distances
before excreting the seeds, excreted the seed in unsuitable places or
if the mammalian digestive system damaged the chilli's seeds.
