BIRD TASTE-BUDS
& NOSES
bill of a male mallardIt's not really known for sure how well the sense of taste is developed in birds, but a good guess is that it isn't as sharp in them as in us.

You can see a nose-hole, or nostril, on the beak of the male Mallard duck at the right.

Some birds have shown amazing smelling abilities. Turkey Vultures, common sights in summer skies above open country in nearly all of the US, can smell rotting flesh from great distances. When a long pipeline sprang a leak that couldn't be located, engineers pumped a chemical through it smelling like rotting flesh, then noted where the vultures gathered!
