The Angry Birds - Ross rejoices is a coloring page that features a very angry looking bird. Its eyes are wide open, its mouth open in a sort of shriek, and its neck is extended. It stands upright, its wings spread out, and its talons visible. A colorful backdrop of trees and sky provides the perfect setting for this grumpy avian. To make Ross look even more angry, try coloring the bird in shades of red, orange, and black. Then, shade the beak and wings with a strong yellow hue. For an even more menacing look, use a deep shade of purple for the eyes and beak, and orange for the feathers. Finally, add a few splashes of green and blue to the background, to create a vivid and vibrant scene.
