Nice photo and I appreciate you posting this series of photos from the Gembira Loka Zoo! This parrot might have been labeled as a Turquoise-fronted (Blue-fronted) Amazon, but I think it's actually an Orange-winged Amazon (Amazona amazonica). Orange-winged Amazons also have a blue forehead, but they also have a yellow crown like this parrot has (which is usually lacking in the Turquoise-fronted Amazon) and the yellow cheeks that this parrot has, but which are greatly reduced in the Turquoise-fronted Amazon. I'm also more than a little surprised to see a Dieffenbachia (Dumb Cane) plant in the exhibit. I thought this plant was poisonous to a lot of animals but maybe they aren't as bad as I was led to believe or the parrots learned quickly not to chew on it?
