Sparrows

 A couple of sparrows.  Sparrows are tough for Gloria and I to ID.  There are so many different ones and so many variations in plumage.  But I think both of these are song sparrows, one a yearling still developing the adult plumage.  

Images were made at the Whitewater Draw Wildlife Area in Cochise County AZ.
