Still working on getting the great shot of one of these guys (Black-hooded Parakeet). They tend to stick to the safety of the trees, but one of these days... Meanwhile, here is a shot that gives an idea of the rich colors these birds have.
Converted in DPP from RAW, adjusted color and sharpened in CS4.
