Mr. Bird, negation, and *ivorousness



I think the reason for my intuition that statements of the form "Mr. Bird
is *ivorous" are false is that "is *ivorous" has a negation in it.
If "X is carnivorous" means "X does not [contradictory negation] eat plants",
then "Mr. Bird is carnivorous" is false, since there he is, over there,
eating birdseed.  And mutatis mutandis, "Mr. Bird is herbivorous" is also
false.  These follow from the (I hope) uncontroversial view that if a
statement is true (false), its contradictory negation is false (true).
