Baby Finch?

The sun is getting real low...but not so low that I can't see something in front of the sidewalk.  It's a baby bird.  It's not taking off nor taking evasive action.  The camera shows more light than I in actuality.  I don't touch it.  Where is mama bird?

It's a mutant or diseased?  Did mama bird kick baby bird out if the nest or abandon it?
