Humming Birds Sing With Their Pony Tail or Beard

Humming birds make a different chirping sound, and it sounds exactl like bird tweeting. They tweet but not with their mouths, with their feathers. So there is only one known piece of dna invertebrates with the ability to taste sweetness,. And humming birds don't have it. Even though they're drinking all this nectar stuff, we don't think they can taste sweetness. O reallyits magic i think there's a theory though, that they modified Their mami gland which has evolved to taste sweetness. Which what that might mean is, when they're going around tasting all these flowers 15 hundred times, it actually tastes like a greg steak bake. Ha hah
