This period features the peak movement of Northern Saw-whet Owls. The best conditions for observing this are during a dark night with cold temperatures and a light north wind. Halloween night was such a night. While trick-or-treaters were roaming neighborhoods, so were the owls; a total of 74 Saw-whets were caught and banded between sites in Lincoln and Northbridge. The Drumlin Farm site had a record season with a total of 371 Saw-whets, 300 of which were banded during October. The previous high was 296 in 2010 and 2012. There was a good flight of Common Nighthawks in early September, especially in Northampton with counts of 368 on September 1 and 269 on September 8; late reports included October reports from Wayland and Princeton. The last Whip-poor-will heard on Plum Island was on September 12, the same date as in 2015.
