American Toad | The Music of Nature

ThunderToads

During our discussion of what makes a recording relaxing, my friend Dorothy Gracey commented that “distant thunder/rain and a soft frog chorus would be heavenly.” So I’ve decided to give her what she wants.

I made the following recording, which I call ThunderToads, in early April of 2000, at Land Between the Lakes, Kentucky (which you’ve probably gathered is one of my favorite places to record). A thunderstorm was passing by, though mostly in the distance. Several American Toads were sounding off from a wetland next to the road, and Spring Peepers were singing lightly in the background. After many rounds of thunder, it finally began raining:

This soundscape is one of nature’s finest lullabies! The toads are lovely and the distant thunder is soothing. The entire recording lasts a little over and hour. I intend to offer it for sale as a sleep aid. Whatya think? Might this recording help you transition into the land of heavenly slumber? I almost fell asleep while editing the recording for this post!

NOTE: Please don’t listen to this recording using tiny little speakers. If you do, you won’t hear the lovely low frequency rumble of the thunder. I advise using a speaker setup that is accompanied by a subwoofer, or else listen using headphones.

Treefrog Mates With Toad?

Thunderstorms dropped heavy rain on western Kentucky on April 24, so I wasn’t surprised that frogs and toads burst into action that evening:

Frog and Toad Chorus with Lang talking – recorded 24 April 2010 by Lang Elliott at Land Between the Lakes, Kentucky.

The major species singing were the Cope’s Gray Treefrog (Hyla chrysoscelis), whose song is a brief rattling trill, and the American Toad (Bufo americaus), whose song is a long musical trill. Below I feature recordings of both. I also heard Spring Peepers and a few calls from Northern Cricket Frogs. I may have even heard an Upland Chorus Frog.

My real “catch of the night,” however, was finding a male Cope’s Gray Treefrog mounted on top of a male American Toad, in the mating position known as “amplexus”. Do these two species hybridize? Heavens no, and anyway, these are both males! Nonetheless, I presume the treefrog is happy with his catch, unaware that the liaison will not lead to procreation. Is the toad “happy” with the arrangement? I bet not—perhaps “annoyed” is a better word for his state of mind. One wonders why he doesn’t just “shake it off” and get on with his life:

Parallels with human behavior are obvious—misguided “attachment” contributing to a relationship that obviously isn’t going anywhere. Sound familiar?

First off, here is a closeup of two male Cope’s Gray Treefrogs, with an American Toad periodically sounding off in the background:

Here is a clean recording of the melodic trills of an American Toad, the same toad that calls in the background in the above recording:

Here’s something special. In this chorus of Cope’s Gray Treefrogs, listen for occasional “chirping squeaks.” These are the aggression calls of the males, given by a an upset male when another male gets too close (I’ve marked the locations of the chirps with “x”):

One last recording. If you were listening carefully when you watched the featured video, you will have noticed a Whip-poor-will singing in the background. Well, I chased him down and got a fair recording. It was a little breezy and there was a whooshy stream nearby, but this is special: my first whip-ppor-will recording of the season. I’ve been hearing them at Land Between the Lakes for two days now. Enjoy!:

American Toad Dreams

Henry David Thoreau referred to the mating call of the American Toad as “the dream of the toad.” In his diary entry of October 26, 1853, he remembers back to spring and the day he first heard those magical sounds:

“I was going home to dinner, past a shallow pool, which was green with spring grass, and where a new house was about being erected, when it occurred to me that I heard the dream of the toad. It rang through and filled the air, though I had not heard it once. And I turned my companion’s attention to it, but he did not appear to perceive it as a new sound in the air. Loud and prevailing as it is, most men do not notice it at all. That afternoon the dream of the toads rang through the elms by Little River and affected the thoughts of men, though they were not conscious they heard it. How watchful we must be to keep the crystal well that we are made, clear!”

The song of the male is a long, melodic trill sometimes lasting thirty seconds or more. It is especially beautiful when heard at a distance. Each male in a chorus sings at a slightly different pitch. Songs in a chorus come and go and overlap one another to produce a dreamy, musical effect that is quite pleasing to the ear. As Thoreau so elegantly points out, one must listen carefully in order to hear the distant and often subtle dreams of the toads when they fill the air.

American Toads are found throughout much of the East (see range map) and breeding occurs after warm spring rains. When breeding is at its peak, excited males will grab almost anything that moves, in hopes of snagging a female. Wiggle your finger in front of one, and he will immediately clasp it with his forelegs. If a male grabs another male, the unfortunate victim will struggle to get to free, making squeaking “release calls” and vibrating his midsection, as if to say “let go of me, you idiot!” (see below for a recording of release calls).

Finally, when a receptive female approaches, the male will climb on top of her and clasp her tightly, his forelegs just behind hers—the classic frog and toad mating position called “amplexus.” The female, who is gravid (full of eggs), is usually much larger than the male. She then swims to an area in shallow water where she lays long strings of eggs, the male fertilizing them as they emerge from her cloaca. When egg-laying is done, the male releases his hold and returns to the chorus where he will continue singing in hopes of attracting another female.

The American Toad is an “explosive breeder,” meaning that breeding erupts quickly when the weather conditions are right—after warm spring rains—and may be over within a few days. This depends on the weather, of course, and breeding may be extended if conditions remain marginal over long periods.

What follows is a recording of a single trill followed by the squeaky release calls of a male that has been mounted by another male:
