Caption

Lesser Nighthawks (Chordeiles acutipennis) sit on the ground of the chaparral hilltops and trill this toad-like trill on the summer nights around central Arizona. This one was at Peck's Lake [Arizona] May 20th, 1999. The sound is very hard to localize, since it is so low, quiet and "generic" (high-pitched sounds are much easier to find), and they are generally closer to you than they seem to be.
