Neil Gilbert of OC Birding found a parrot that he does not know the identity to in Irvine Regional Park, Orange County, California. Does anyone want to help him figure it out? He’s got good pictures here.
Corey is a New Yorker who lived most of his life in upstate New York but has lived in Queens since 2008. He's only been birding since 2005 but has garnered a respectable life list by birding whenever he wasn't working as a union representative or spending time with his family. He lives in Forest Hills with Daisy, their son, Desmond Shearwater, and their indoor cat, B.B. His bird photographs have appeared on the Today Show, in Birding, Living Bird Magazine, Bird Watcher's Digest, and many other fine publications. He is also the author of the American Birding Association Field Guide to the Birds of New York.
It is a hybrid. Most probably:
Yellow-crowned Amazon (Amazona ochrocephala) X Blue-fronted Amazon (Amazona aestiva)
In stead of the yellow-crowned it could also be a yellow-headed (Amazona oratrix) those are closely related.
It is probably also listed here: http://amazornia.us/gallery_BF_YH.html
Some kind of Amazon hybrid.
