Tonight, August 15, we had a spectacular aerial show with Common Nighthawks, Tree Swallows and gulls. The nighthawks were swarming over our Curve Lake house. I would estimate 50 but it was difficult to count because of the irregularity of their flight. There were also about twenty gulls and 100 tree swallows at the same time. About the same number of nighthawks (45) as August 25th, 2012. In 2012, they all were flying on an easterly course over Kutang Island on Buckhorn Lake which made it easy to count them. I managed to snap a photo of tonight’s show to give you an idea of what one part of the sky looked like at any given time. Not a great photo for seeing details of the birds but it is more for the pattern of flights. The show lasted for about an hour.

The same flock (of 50 nighthawks) were flying and feeding above the straight-stretch between the Quarter Mile Gas Station and the Waste Transfer station in Curve Lake on August 20. They might be doing so every night, I’m not sure because sometimes I forget to look up. It is good to see though. I wonder if Curve Lake is an evening gathering place for the local birds.

Note:  It is most likely that the nighthawks were migrating southward, despite the somewhat early date. A swarm like David describes with swallows and gulls often forms when birds are feeding on mating flights of ants. D.M.

On the morning of May 17 on roads west of Highway 7A, there were abundant Bobolinks, Eastern Meadowlarks, two Brown Thrashers, Savannah Sparrows, Eastern Kingbirds, Tree Swallows, and several Baltimore Orioles together in a shrub.

Today, at noon, there were hundreds of Tree Swallows flying around the pine trees at the entrance to Millenium Park on Water Street. They appeared to be feeding on something – possibly midges?

(Note: I also heard that on April 7, there were “thousands” of Tree Swallows flying over Champlain Heights in the north end of Peterborough. D.M.)
