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.

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:

  1. Excellent video! I always love it hear in Michigan, when I hear a large distant chorus of toads. I can see why Henry David Thoreau called it “The Dream of the Toad.” I love the part in the video when the males are fighting, and that huge moth lands in front of one of the calling males. On many occasions, I have had a male toad mount my finger when I pick one up, and make release calls.

  2. Love your website and all you are doing. These are precious sounds.
    I am so confused trying to figure out what I am hearing. I have loved this sound for years and always thought it was tree frogs. Finally I try to figure out what it is and the closest I can come to is American Toad, which I know are here because I run into them on the back patio from time to time. But the trill is shorter then the toad in the recordings and they are chorusing now, in October, do they do that? Thank you for any clues!

    • Trendle: Where do you live? And what are you calling a “chorus”? Also, are you hearing the trills at night or during the day? American Toads and most other frogs do not sound off in October, so it must be something else. Fill me in on the details and maybe I can help.

  3. Beautiful. I’d love a 1/2 hour loop of this on a cd. The childhood memories of our pond just pour over me. It makes this crazy world go away for a while. Love it!

  4. I live in nj but own land with a pond in ny state.I was there this weekend 5/1 and the toads were singing all night my wife son and dog sat outside and listend to them very calming and so cool.
