Lost Maples Moonlight Serenade

My adventure began not long after dark, as I hiked a trail that led up a valley next to a stream. I was thrilled to hear Barking Frogs calling from high on limestone bluffs above the trail, but the stream was too loud and the frogs too far away to get a pleasing recording. I tried climbing up to them, but the slope was much too steep and dangerous. So I continued up the valley. The night was magical. It was dead calm. The moon was full (or nearly so) and I was able to walk safely without using my headlamp. The temperature was around 70 degrees Fahrenheit (21C) and the humidity was fairly high—perfect conditions for the Barking Frogs. If only I can get closer . . .

I remember scaring up two small herds of wild pigs, the pitter-patter of their small hooves fading into thick brush. At long last the trail began descending into the next valley, switch-backing down a limestone bluff above another stream course. It was here that I encountered several Barking Frogs and discovered that they were giving their gagging croaks from under large boulders or else from crevices in the limestone. No wonder their calls sounded muffled and resonant. I was pleased to get a nice recording of several males calling back-and-forth, punctuated by the soft chirps and trills of Cliff Chirping Frogs:

After gathering a number of closeup recordings, I made several attempts to get a nice soundscape. My efforts generally failed until I droped down to the stream. At 3 am I captured my favorite portrait, a true “moonlight serenade” featuring a single Barking Frog sounding off from the bluff above the stream, with distant cricket frogs and cliff chirping frogs coming and going against the gurgling backdrop:

These recordings bring back my fond memory of walking the trail alone under soft moonlight, enveloped in a unique and extraordinary soundscape so different from what I’m used to back home. I remember enjoying the beauty and solitude, yet I wanted to share the magic with at least one other person. Returning to the campground just before dawn, I phoned a close friend who I thought would understand, and left a hurried description of my experience on her answering machine. The sun rose and the magic evaporated from view, yet a lasting and poignant impression had been made on my mind.


  1. Excellent recordings! I’ve never to been to Texas or Arizona and hence have never seen or heard a Barking Frog. They do look unusual, and they sound somewhat unusual too.

  2. Just love that second recording with the sound of the stream behind it. Could sit there and listen to that for a long while.

  3. Lang you’ve recently posted soundscapes such as this one that are quite foreign to me, from places I’ve not been and creatures I’ve not met. They inspire great wonderment and a delighted incredulity, and I am glad to have such diverse opportunities to reach into the world beyond the bit of it I know.

  4. Awesome. I love both recordings. The portrait of the Barking frogs gives a feeling of solitude and I can just imagine the filtered moonlight on the trail. The soundscape has a lot of dimension. Certainly one that I haven’t experienced.
