If birds are fancy dancers, are they smarter, too?

Does a male bird with a long and complex courtship dance have superior cognitive abilities? Simply put, is a talented dancer a smarter bird? To answer the question, researchers at Université de Montréal studied the zebra finch, a small bird known for the dramatic differences between the male and female of the species. The scientists wanted to determine whether females choose males who perform elaborate dances because those displays reflect above-average intelligence.
