I saw the Peregrine Falcon, while up watching the two Snow Geese on the Reservoir.  The falcon was in one of its favorite trees for at least an hour.  It got harassed by six American Crows.  I left to go look for a Wood Duck on The Pool before returning to look for the Peregrine Falcon on the El Dorado.  I stayed late to see if it would roost on the south face of the south tower, but it took off after sunset going south southwest and was quickly out of view.  This falcon is going to be hard to figure out!
