At the close of a summer day, the songbirds go silent. As if on cue, the birds of the night make their voices known. In an Eastern woodland, the eerie trills and whinnies of an Eastern Screech-Owl are among the first sounds of the night. Meanwhile, as night falls west of the Rockies, a Western Screech-Owl (like this one) calls out. But there’s another bird whose voice will drown out the loudest of screech-owls: the Barred Owl! Pairs may break into a rollicking duet, sometimes called their “monkey call.”
