Its a good question. In flight the wings are most of what is visible from the ground. The body is relatively small, so camouflaged wings are often sufficient to hide them if they're flying high enough (if they're flying low, with their size no amount of camouflage will hide them). A lighter underbelly can also break up the body's silhouette.
With the darker blue of his wings, night flying is better for him.
