The seed passes unharmed through birds, and this is in fact a mechanism for spreading the seed. Birds have no receptors for the capsaicin. Sort of a symbiotic relationship. I personally am glad to belong to the class of creatures in whom seeds can be digested :) Also, I have seen, in Walmart, bags of pepper being sold for the especial purpose of mixing with birdseed to discourage those bad old squirrels. They apparently don't appreciate the heat. ~~~~~~~~~~~~~~~~~~~~~~~~~ Rick Lindstrom <rlind@nettally.com> Tallahassee, FL ~~~~~~~~~~~~~~~~~~~~~~~~~
