What bird is gray with a red head?

It could have been a juvenile cardinal missing head feathers. The siblings sometimes pluck each others feathers out. And the bill or beak wouldn't have turned the bright red color that males get when they mature, the females have a very pale peachy colored beak.

The pigment of their skin is also black to a dark pasty grey, visible when the feathers arent' completely formed or are missing.

I found a link with pictures: check it out because only you know what you saw.
