Tree Swallows, Tachycineta bicolor
One of the sign that summer is ending is when the swallow join in flocks, ready to migrate. Tree Swallows, Tachycineta bicolor, often find a bug rich area to stoke up for the journey and often remain there for a few weeks. Here in Ontario, sewage lagoons are a favored spot as is true for sandpipers and plovers. It is not unusual to see thousands along hydro lines, trees and fences.

Nice shot. It looks like they are all taking a good nap before embarking on the journey. They certainly look well-fed.

Thanks Hilke,
They must take care of a serious amount of insects.
