Two recent daytime expeditions to photograph the spring peepers (Pseudacris crucifer) inhabiting a wetland-like area not too far from my house produced several sound recordings of their incessant calls, but no photos. I failed to see a single frog, although the snails co-inhabiting the place didn't escape my attention. So last night I followed Fred Schueler's advice, donned my headlamp and rubber boots and went out at dusk.
The frogs were calling all around me as I squatted at the edge of the swampy area with camera in hand. For many minutes I looked and looked at the spots brightened by my headlamp, but just couldn't see a frog. I was puzzled about how they could be so noisy and invisible at the same time. Just as frustration was setting in, I finally noticed the inflated vocal sac of one, my 1st spring peeper sitting by a skunk cabbage.
Once I knew what they looked like and how small they were, I started spotting them left and right. Eventually, I even caught one and held it in my hand long enough for a few shots. The picture below will give you an idea of an adult frog's size.
And here is one of the recordings I made with my iPhone. Against the background cacophony of countless frogs, you will hear the peeping of one Pseudacris crucifer.
