Two green-winged macaws fly over the audience in the National Aviary's free-flight theater, then land on separate agility courses. A race ensues between the feathered siblings, Ben and Betsy, to see who can complete the system of ropes and pulleys first. Betsy wins this time, and the crowd goes wild.

This is one of a number of bird intelligence tests featured in "Bird Brains," the current interactive show at the Aviary.
