The Indianapolis Zoo's new entrance way is almost completed. It should be finished within the next month.
There have been rumors of the White River Gardens being refurbished and changed into a Rain Forest exhibit with actual animals. This won't happen for a couple of years down the road.
Flights of Fancy's construction is progressing quite well.
Here is a list of the bird species they now of. More should be added to the list down the road:
Caribbean flamingos, rainbow lorikeets, black-capped and red lories, crested wood partridge, Cabot's tragopan, Taveta golden weavers, superb starlings, budgies, cockatiels, southern ground hornbills, helmeted Guinea fowl, turacos, yellow headed Amazonion parrots, and a cockatoo.
