Did you know that birds -- from hummingbirds to larger species -- have a taste for artificial sweeteners? The artificial taste of the sweeteners is very appealing to them, and the packages are often swiped from outdoor dining restaurants by mischievous birds. However, in the long run, since they have no caloric value, they should be kept away from birds at all costs. Birds that develop a taste for artificial sweeteners can quickly starve to death because they are getting zero nutritional content. Keeping the packets away helps birds maintain their natural diet.
