Last evening between 7:30 and 8 pm, from an upstairs window in our home, we could see above the roof tops, there was a gathering of many 100's of Vaux's Swifts, swirling over the large chimney at the rear of Wiegand Hall on the corner of 30th and Campus Way. We were not able to watch long, but it appeared some might be going in and out. Susan Brown
