Last night, I got to see Chimney Swifts for the first time. I was in the Fredericton area and met up with Don Gibson. After reading this post from Nature NB http://www.surfbirds.com/birdingmail/Mail/NatureNB/1420748?year=2013, I asked Don if he could show me where they were. He didn't think they were still there so we were both pleasantly surprised to get to watch more than 80 of them for about twenty minutes. I posted a short clip below where you can hear them and if you look closely, see them flying about (it was past 9:30 and the sun was already down).
