Orange-chinned parakeet

Good question!! I think mine is a good example to show why it is called orange-chinned. Most of the smaller parrots in Central- and South America are mostly green, so you need some color markings for the name. If you look carefully you may notice the orange chin, that's why it is called orange-chinned parrot. Or you have the yellow-fronted parrot or the blue-headed parrot which is in German the black-eared parrot. For Jugularis the brown part of the wings is also characteristic.

such a lovely spotting ,really nice!!
