First Juvenile Cardinal of 2013

One by one the first juveniles of the season are making their presence known.  I have already seen the first young House Finch, suspected a White Breasted Nuthatch, and plausibly a first chickadee.  This weekend saw the arrival of one or two young cardinals.  The bird(s) in question were already finding food for themselves and didn't beg at any time.  And they sure look strange!  I am looking for peers from other species.  Bluebirds? woodpeckers? wrens?  We shall soon see!
