Name That Bird Call in Duke Gardens?

The birds in the Blomquist Garden of Native Plants were singing en masse on a recent winter morning. See what attracts them to the Piedmont Prairie in this brief video, courtesy of Blomquist Gardens' curator Annabel Renwick.

During the pandemic, the avian cacophony is as loud as ever. Can you hear the blue jay mimicking the hawk's "fier" call? The "peter, peter" of the titmouse or the "fee bee bee" of the chickadee? You're welcome to challenge yourself to name the bird calls.
