While I was working around 2 pm this afternoon, my eye was caught by commotion and motion: A Merlin zoomed by heading west, at eye/6th story level, scaring the birds. Then a couple of minutes later a migrating (I presume) small accipiter put up the birds again as it headed south.... Not even 10 minutes later there was a _huge_ commotion......and after a short time a large peregrine came rocketing from the east, over the large low building in front of me, turned toward my window, then flew off to the south and east. About a minute or so later it returned from the south, but this time from over the 11th story level roof of my office building. It quickly dropped in altitude, to about 6th story level, as it passed to the north. It dropped down a little more and continued to head north, then east around some buildings before it was completely lost from sight zooming west. Confused? Dizzy? Just know this: it came within 60 to 75 feet of my office window, flying fast! And then, while I was talking to a coworker and we were still looking out....a ball of starlings brought my attention to a distant Merlin (this time I actually had my binoculars out). This little baby was circling higher and I soon lost it while trying to point it out to my coworker. I don't know if this was the same as the bird I had seen earlier. By now it was close to 2:30. And around 3 pm or later....what should appear but a hunting Merlin, initially heading east to west. My coworkers were able to note the smaller size of the Merlin compared to the larger falcon they had recently seen at the same distance (literally). This Merlin was in view off and on for two or three minutes (or so before it disappeared and we had to return to work. It put on quite a show, chasing pigeons around. It almost landed on a high window-ledge of a building, but then flew off. Simply: two hunting falcons of different species, within a few minutes of each other. I don't think I've had them so close in time out my sixth story office window. Rob Hilton Bethesda, MD Rob Hilton robert@csa.com
