[EBB Sightings] Large falcon at Calaveras Rd

Yesterday, while biking south on Calaveras Rd. near the reservoir, a large 
gray falcon "dive-bombed" a field rodent directly over me (this was about a 
mile south of the Bald Eagle nest).  It was either a Peregrine or Praire 
Falcon, hard to tell without binoculars, but quite spectacular!
