Great green macaw - I had to look it up as well as the zoo and zoo map.
sadly they did not have an animal list but thankfully typing "green macaw" on google coughed it right up. lol
all hail Melanie leader of the flock
edited - it could also be a somewhat smaller Military macaw , nearly identical except it's smaller in size then the Great green macaw
27 inches in length compared to 35 inches of the Great green macaw
