The Waterfall Aviary now houses an incoherent mix of Asian, African and Neotropical species, including a large number of the park's surplus Nicobar and Pied Imperial Pigeons (the park has over 100 Nicobars and 80 Pieds...). More South American species have been added recently, including Scarlet Macaws, Blue-throated Piping Guan, White Ibis and Roseatte Spoonbills.
