Every day on the way home from DC I watch the RFK parking lot and  
river (south side) as the Metro comes out of the tunnel toward New  
Carrollton.  Normally, don't see anything out of the ordinary, just a  
bunch of Ring-billed Gulls, but once in a while something unusual is  
there.  A few weeks ago it was a Cooper's Hawk on the ground just off  
the RFP blacktop, standing in the grass with dinner.  Yesterday it  
was 6-10 Black-backed Gulls in with the Ring-billed Gulls on the  
parking lot.  Today it was 4 or 5 Black-backed Gulls in the water and  
a Little Blue Heron standing on the tree stump.  (no mud flats, high  
tide).  Nice surprise.
