Horses have poor digestive tracts. They don't digest food terribly well. Additionally, back in the day, horses ate oats regularly, which are known for their tough husks. As such, many of the oats would pass directly through the horse's digestive tract and come out softened, but not digested at the other end. In the days before cars, horses regularly did their business on the roads. After they made their deposit, birds would come and dig the oats out of the manure. Since these oats weren't eaten by anyone else, the saying developed that it was for the birds. In other words, when you say something is "for the birds," you are really calling it horseshit.
