During interactions Whip-poor-wills make a Swainson's Thrush-like whip. Here a bird is singing, then a second bird flies by calling and then begins to rapidly sing (Apr, NJ).





Chuck-will's-widow at dusk, Dividing Creek, NJ (May).













Chuck-will's-widows have a number of calls (before sunrise, May, DE):
Heron-like quok calls by bird that was at least initially in flight.













Growls and clucking calls

Wing claps (May, DE).




Common Nighthawk peent and "boom" where the bird dives and creates a sound with its primary wing feathers (dusk, May, NJ).

This bird, which appeared to be stationary, made grating noises in between peents (4.56am, July, ME).





The American Woodcock call is similar to that of the nighthawk (dawn,Feb, NJ).
