It's baby peregrine falcon season. We know because we've heard mom and dad's screeches from their nest in St. Michael's Church here in Old Town. If you put your feet in the shoes of a little church mouse for even just one moment, it's a terrifying sound.
Evanston Public Library also knows the joy of peregrines as they have a FalconCam set up. Take a peek at their new baby falcon here. It was born May 17.
Listen to the peregrine falcon's call here, but it's not quite the screech I've been hearing.
