Having completed a series of cognitive tests, a European starling is released into the wild. The European starling boasts a remarkable repertoire. Versatile songbirds that learn warbles, whistles, calls, and songs throughout their lives, starlings rank among the most advanced avian vocal learners. Now a new study published in Science finds that starlings, along with other complex vocal learners, are also superior problem solvers. "There is a long-standing hypothesis that only the most intelligent animals are capable of complex vocal learning," says Jean-Nicolas Audet , a research associate in the laboratory of Erich Jarvis at The Rockefeller University.
