I think its because they have no permeability on their tongues. Meaning moisture cannot penetrate it, so the calcium cannot penetrate and hurt their nerve endings. Or maybe its the lack of moisture overall, since they have no saliva, so they have no medium to carry the capsaicin to the inside of the flesh on their tongues. Fun fact: that's why the expression "it's glued on with bird saliva" means the thing is not glued/nailed/screwed on properly and could fall appart at any moment.
