Christopher Hadin journal entry -- "August 22, 2005
This evening at dusk there was a steady migration of what appeared to be Swamp Darners heading due west. Most were flying too high to catch. I went to the corner of Cottage and Osborne (in East Norwalk Connecticut) where I had a clear and unobstructed view of the sky to the east. A few came in low and I was able to catch and photograph one. The little bastard bit me with a surprisingly firm and painful pinch. I did see a few that were not moving from E to W and appeared to be feeding, but the vast majority were going in that direction. There was about one every 10 seconds and sometimes two or three came flying through together. I also noted that Green Darners were present, though not in large numbers." … Christopher Hadin, 12 September, 2005
