South America: Chilean Flamingo, Roseate Spoonbill, Scarlet Ibis, Brazilian Teal, Southern Lapwing, Wood Storks Boat-Billed Heron (possibly Orinoco Goose)
North America: Blue Grosbeak, Indigo Bunting, Painted Bunting, Rose-Breasted Grosbeak, Northern Bobwhite Quail, House Finch, Gray Catbird (possibly Yellow-Billed Cuckoo)
Africa: Cape Vulture, Hooded Vulture, Rüppell's Vulture, Gray Crowned Crane, Great Blue Turaco, Hammerkop, Vulturine Guineafowl, Radiated Tortoise, (possibly Malagasy Sacred Ibis)
These are not confirmed!!! This was the information circa last summer, and there will probably be more birds than this as well. The South America exhibits will be fully walkthrough, the Africa exhibit is not a walkthrough, and the North America Exhibit will have a small inside viewing area.
For the South America Aviary, the Chilean Flamingos, Roseate Spoonbills, Brazilian Teal, Wood Storks, and Southern Lapwings are alread at the zoo. The Wood Storks are in the savannah aviary, the Brazilian Teals and Roseate Spoonbills are in the wading bird aviary, the flamingos are in the primates section, and there are some lapwings both behind the scenes, and in the savannah aviary, so I don't know which will be on the scenes.
In the North America aviary, I know almost nothing. Sorry!
The Africa aviary is really exciting! I'm assuming the radiated tortoises are going to be the pickle parents (Mr. and Mrs. Pickles). The reason I believe this is because the picklettes are still really little. Highly reccomend seeing them in the reptile house I'm in love with them. The vultures are the ones currently in the carnivore section. We have Mazghoul and Ziggy the cape vultures, Dizzy and Buzzy the hooded vultures, and my sweet sweet baby, Bruce the Rüppell's vulture. I've heard mixed messages about the Malagasy Sacred Ibis being on exhibit, so don't hold your breath.
If you have any other questions please let me know!
