American Woodcock (Scolopax minor)
Peenting: A nasal, buzzing peent, given from the ground at dawn and dusk, before and after the flight display. Similar to and sometimes mistaken for the flight call of the Common Nighthawk. Peents are given mainly by males, but females occasionally give the call as well (Stokes 1989).
