I was experimenting with color temperature settings. This image was shot at a much lower color temperature than the other photos of Gordie in this album. Hence the much bluer tone to her feathers and the silver stand she's perched on.
It's all parts of photography I'm exploring. Greens tend to shoot yellow, I'm noticing. This is a pretty significant alteration to the color temperature of the camera, yet results in the bird's color in the photo matching more closely what my eye sees when I look at her.
