The bird doesn't really look like a toucan, maybe a Red-billed Curassow? Or are there toucans in here too?
This exhibit is called Toucan Terrace, but that also encompasses the nearby Golden-Headed Lion Tamarin exhibit and the adjacent Hawk-Headed Parrot enclosure and the whole area is "Toucan Terrace". However, most of the toucans are free-flying in the vast upper level of the aquarium and DWA is renowned for its world-class bird collection.
