I saw the original Snowy Owl last week and reported it as "all white" after a naked-eye, semi-distant look. Of course, closeup photography showed that it infact had some light barring.  This other bird recently reported definitely looks like a different individual to me, with much more extensive barring and color. I think there may be two owls. 

Otherwise, I've still got lots of Pine Siskins visiting my yard in Silver Spring.
