Beautiful picture. I was actually really surprised to see a Nene deviation in my messages, since they're not very common. I love the details you can see in this shot, too bad the yellow-orange on the cheeks/neck isn't very bright. The colors can be really pretty.
Wow, that's cool. As far as I know, the only place you can really go to see wild Nenes on the islands is Volcanoes National Park on the Big Island. (I live in Hawaii, only on the main island (Oahu) though.) A friend of mine who goes to see relatives on Hawaii said that the Nene hang around the parking lots up there sometimes.
