More than 18 orders and 37 families make up the avian collection at The Dallas World Aquarium. The majority are on exhibit, but some are housed in off-exhibit breeding aviaries. Ranging in size from tiny manakins to large swans and curassows, they can be seen at various levels and in many different habitats (those with a single species, many with multi-species and numerous species) enjoying the free flight, seven-story tall rainforest exhibit.
 
Waterfowl such as Black-necked swans, Orinoco geese, White-faced whistling ducks and Rosy-billed pochards are often seen swimming in the 200,000-gallon River exhibit at the lower level. Finding safety in exhibits are smaller birds such as manakins, tanagers and chlorophonias. With more than 23 species, the facility has one of the largest collections of Ramphastids in North America. Smaller Ramphastids (toucanets and aracaris) can be seen in various habitats but the larger black toucans can often be seen at the top of the 40-foot waterfall that cascades into the River exhibit below. Motmots, grosbeaks, troupials, sunbitterns, capuchin birds and jays provide action and sound within the vegetation. Oropendolas go in or out of their pendulous nests hanging from tree limbs or vines. The bright reddish-orange cocks-of-the rocks can be seen foraging for food for themselves or their young.
 
From small tillandsias, to autograph, mahogany, coffee, black olive, Monkey don’t climb and tall majestic palm trees, the plants provide homes and sources of food and water for many animals, as well as beautiful blooms and smells for the guests.
