Trying to get back his youthful look?

Here is a picture as a baby of two months or so of age -



We used to say he had a "dirty" face, given how uneven the grey/black was. But it was all natural.

Lately, Piper has been hiding under the newspaper that lines the bottom of his cage quite a bit, which means that he's adorable peach/white face has taken a grey-ish tinge..



I wonder if he's trying to recapture his youthful looks?

On a side note, while I think I took a large number of pictures of Piper as a baby, I can't seem to find most of them, which makes me a little sad. Guess I'll have to see if I can't find my old hard rive which might store some of them.
