Barn Swallow babies have fledged, making the number of chattering swallows under bridges, inside of barns, and under eaves greater than usual. This acrobatic aerial insectivore (as in, they fly fast and well, and they eat insects while in flight) is a common bird species in southern Wisconsin. You can find them near any built structure, and they create nests of mud and grass under overhangs.
