I have a fascinating recording of Common Nighthawk at dawn. The Nighthawk =
has a peculiar "peent" nasal sound , and then about once a minute a sound l=
ike a roaring lion. Very disconcerting the first time you hear it. The in=
teresting thing is that on this recording, the frogs are clearly synchroniz=
ed with this roaring sound. I don't know how this might have evolved, sinc=
e Nighthawks are insectivores, but on this recording at least I was able to=
convince myself this was not a coincidence.
