Pigeons can learn abstract numerical rules, a skill that scientists had believed only primates possessed. Although the birds may not be able to do higher math, their ability to reason numerically is likely something that a wide variety of species can do, too, researchers say. Many species, from honeybees to elephants, can discriminate between quantities of items, sounds, or smells, and represent numbers mentally.
