The 2020 season for the Stone Bridge Nighthawk Watch concluded last night with 
three nighthawks seen. As has been the case in past years, the last couple of 
days of the Watch saw little in the way of nighthawk movement. What 
distinguishes this year from the past three were the high number of birds that 
passed through in August, "frontloading" the count. 

Thanks to all who participated. It was wonderful to see and meet so many people 
interested in observing, and learning about, Common Nighthawks!

We'll see you again next year.
