Yesterday afternoon, at about 5:45 pm, David and I were walking to the SRT, across the small empty field beside McCowan Station. A falcon swooped down and landed about 15 feet from us (and landed with quite a thud!), poked around the tall grass for a few seconds and produced a small black critter (a mouse, I think), swallowing it in a couple of gulps. It was such an amazing thing to witness - this bird was definitely on a mission and obviously spotted the prey from the air, and it did not show any concern that there were people so close by. I love seeing these huge, beautiful creatures in the city!
