Hidden Ptarmigan Airbrush Painting

When I was in Alaska, I almost stepped on a willow ptarmigan sitting on her nest. Two people ahead of me stepped right over her without seeing the bird. But my foot was coming down too close, so she fluttered up and away only a few yards, then trusted to her cryptic coloration to keep her hidden.

Using the photos I took then, I did this painting using the airbrush. It's 5 by 7 inches.
