No Crossbill there from 4:10 to 5:40 PM,  Of course the fact that they guy next door was having new gutters and down spouts installed about that time and shortly thereafter, an immature Cooper's Hawk came in and sat about 25 feet above the feeder for 15 minutes didn't help any I'm sure.  I thought patience and persistence would pay off, but not for me.  This was my 6th try.  Maybe next time.  

On a side issue, while waiting for the Crossbill, I noticed a jet black squirrel among the several Gray Squirrels in the area.  I believe I've seen black Gray Squirrels in DC.  Is this just a local aberration or are they a subspecies?  Since this is not a bird topic, please reply off line.  Thanks.
