According to a 1998 paper (Brigham, R.M., M.B. Fenton and H.D.J.N. Aldridge.
1998. Flight speed of foraging common nighthawks (Chordeiles minor): Does
the measurement technique matter? American Midland Naturalist 139:325-330),
timing nighthawks over a set distance indicates a foraging flight speed of 5
m/s (11 mph). However, using Doppler radar, flight speed is indicated at 6.5
m/s (14.5 mph).
