Fluffy brown/white body, black wings with perfect white circles, and stripped tail-feathers?

Today at work, a bird flew straight into a glass window. He appeared to have broken his wing, and so I brought him home to try and figure out what to do. Shortly after, he flew out of my box and disappeared. I have never seen a bird like this before, and it's got me so curious! He was a little smaller than my hand, had a fluffy torso that looked like a blend of black and white, his wings were black with perfect white dots, and his tail was very long, with white and black stripes. His beak was kind of short and black, and his head was blotchy with white and black, also. I have no idea what kind of bird this could be, and I can't find another picture of it anywhere online!
