Today at about 4:30PM I saw two adult peregrines outside our building in 
Silver Spring (@ Colesville Rd x E-W Highway); they were chasing each 
other!  I had a limited brief view (two passes) and only saw them when 
they passed by on my side of the building.  I was near the top of the 
building and they passed at eye level; they were both adults.  I know it's 
early for Atlas safe dates, but am hopeful that this was some sort of 
courtship/pair bonding; I have my fingers crosed!

There have been many sightings of peregrines in this area and Bethesda, 
Rockville, etc., especially during winter; With all the tall buildings it 
seems like it is a natural place for a pair to attempt nesting.  

This was the first time I have ever seen two adults together here.
