TAURUS (April 20-May 20): Why do birds fly? First, that's how they look for and procure food. Second, when seasons change and the weather grows cooler, they may migrate to warmer areas where there's more to eat. Third, zipping around in midair is how birds locate the materials they need to build nests. Fourth, it's quite helpful in avoiding predators. But ornithologists believe there is yet another reason: Birds fly because it's fun. In fact, up to 30 percent of the time, that's their main motivation. In accordance with the astrological omens, I invite you to match the birds' standard in the coming weeks. See if you can play and enjoy yourself and have a good time at least 30 percent of the time.
