Late summer nights are very noisy in my back yard. First, I hear three species of cicadas singing in the trees. Then I hear more and more kinds of crickets, as afternoon becomes deep night. Then katydids. Then what sound like tree frogs—probably, actually, Eastern American Toads and tree crickets, going by the sounds in the links below.
All this nature is lovely, of course, and when one is in the right frame of mind, one can imagine they are singing their little ones to sleep.
Nope. They are either, uh, carrying on, or seeking to carry on, with female individuals of their species.
The frogs in my trees are Eastern American toads (Bufo americanus americanus)

The crickets turn out to be even more complicated, as tree crickets tend to sound like frogs, while ground crickets more often sound like crickets. (Nature is indeed a mother. And a father.) So far I know we have these crickets:
carolina ground cricket
spring and fall field cricket
black-horned tree cricket
broad-winged tree cricket
Davis’s tree cricket
four-spotted tree cricket
narrow-winged tree cricket
two-spotted tree cricket
This snowy tree cricket sounds just like our tree frog. Toad. Whatever.
And—bonanza!—here’s a site where enterprising soul John Himmelman has made a mix of dozens of crickets and katydids, with entymology notes! This is far more variety than I hear at night in my back yard, but it’s entertaining to hear the amazing range of these concupiscent creatures.
What do you hear outside your window at night?
