Hi, Well! I was excited to see a Common Nighthawk pass by tonight at about 7:35. Little did I know that it was leading 553 other birds!!! Starting at ~7:35 tonight, a steady stream of Common Nighthawks migrated south along the Olentangy River. It was mostly a steady influx of birds in single file, but there were a few groups of 70-100 birds. There were Chimney Swifts in the area, so I made sure to not confuse the two species. These two species are superficially similarly shaped, but fly quite differently. The swifts were zipping around and flapping their wings as if they were vibrating, and the nighthawks had slower, deeper wingbeats, and glided much more frequently. In addition, the nighthawks had longer tails than the swifts. For the closer individuals, the white wing patches on the nighthawks were easy to see.
