Can you find the bird in the photo below?
The camouflage function of feathers is fascinating. I think the Hermit Thrush has a combination of several kinds of camouflage: cryptic coloration, disruptive coloration, and countershading. In the first, the coloration of the feathers is similar to the environment in which the bird forages or nests causing her to blend with her surroundings. That would be the soil, sticks, rocks and decaying matter covering the ground--all that gray and brownish neutral you see around the bird that she matches so well.
