These are swallows that have evidently just arrived in Griggs Dakota.
There are thousands of them eating mosquitoes and other insects.
I am told that they are Cliff Swallows. There is a shortage of cliffs in GriggsDakota.
So they are clinging to my house.
Clinging to the screens.
or above the windows, and sometimes swarming under the soffits to snap up juicy insects.
It has been going on for a few days now.
They seem to come and go.
I haven't noticed any muddy construction projects.
Cliff Swallows build a mud house with a round opening similar to a bird house made by people.
I have never seen this many swallows swarming and swooping for hours around here.
Which gives me hope that no matter how old I get, I will never see it all in GriggsDakota.
