Stephen, 
Not sure about a nest, but I work in Silver Spring and have periodically seen the peregrine for the 3+ years I've worked there.  He/she frequently hangs out near the metro station (I work at NOAA direcly next to the station).  Adds a little spice to a meeting to see it fly by the window!  Jeff Shenot might be able to give a better indication of how long its been in the area.

Hi Rob and all

A month or so ago, a friend who is knowledgable about birds reported seeing a Peregrine flying between the buildings near the Silver Spring metro station, in downtown Silver Spring. Is there a nest site nearby?

Cheers

On Wednesday morning we were surprised to see an adult Peregrine Falcon flying north paralleling Georgia Avenue in downtown Silver Spring, carrying prey.  It passed 150-200 from our car in somewhat labored flight.  

Yesterday afternoon while near the Capitol on a non-birding outing we saw an adult Bald Eagle fly a hundred yards or so over us on the National Mall, heading toward the Capitol.  A few minutes later, a Peregrine Falcon swooped and landed on top of the statue which tops the Capitol dome; it was quickly joined by a second.  In the medium distance we could still see the Bald Eagle, then saw a second and more distant eagle.
