I forgot to mention, but the Keas are off display in the building behind Wings of the World (not a public building) until the colder months.It appears that the Keas are no more. The Kea Encounter/Free Flight Aviary has reverted back to it's original roots.
From their Facebook post:
Our newly renovated free-flight aviary is now open from 10am-3pm daily. Come in and visit with some amazing feathered friends including the inca tern, magpie goose, nicobar pigeon and more! [There's also Gulls]
