I think this zoo was amazing, all except the falcon in the aquarium which leg was chained to a tree branch!!!!!!!!!!!!!! I cant understand how a zoo who prides itself on animal education and for the most part, had very nice living environments for most of the animals, could do this to a bird whose entire existence is on spreading its wings and flying!!!!! A sign read that it was let off for feeding twice a day, HOW IS THAT ENOUGH?????????? I am so saddened by the thought of this birds terrible existence!!!! I hope someone from Wildlife World zoo reads this and takes my opinion into consideration and gives the bird the freedom it deserves! By the way, I am sure this is not the first you have heard of this, a lot of people around me were voicing their similar opinions!!!!!!!
