Behavior

The Southern Chorus Frog is a secretive terrestrial resident of the American Southeast. Unlike many of its tree-dwelling relatives, this species spends the majority of its life on the ground, masterfully camouflaged among fallen leaves and low-growing vegetation. They are often described as 'ghosts of the wetlands' because they are far more frequently heard than seen, especially during the cool winter and early spring months when their breeding season peaks.

These frogs are highly sensitive to vibrations and movement. When approached, they will instantly cease their calling and dive into the water or burrow deep into the leaf litter. Despite their shy nature, they are prolific singers. Their call sounds remarkably like someone running a thumb over the teeth of a plastic comb, and when a large group gathers, the sound can be heard from a significant distance.

Camera Tips

Capturing the Southern Chorus Frog on camera requires a specialized approach because of their small size and ground-dwelling habits. For the best results, position your camera just 3 to 5 inches off the ground. Aim the lens toward a 'calling site'—typically a small clump of grass or a half-submerged log at the edge of a shallow, temporary pool. Since these frogs are so tiny, using a camera with a short focal length or a dedicated macro lens will ensure the image isn't a blurry smudge against the mud.

Standard PIR (Passive Infrared) motion sensors often fail to trigger for cold-blooded amphibians because they don't produce enough heat. To combat this, set your camera to 'Time Lapse' mode. Configure it to take a photo every 30 seconds to 1 minute during the hours immediately following a rainstorm. This increases your chances of 'catching' a frog as it emerges to feed or find a mate. If your camera has a 'Sensitivity' setting, turn it to its highest level to catch the slight movement of a hopping frog.

Timing is everything with this species. In the Southeast, the Southern Chorus Frog is most active when other wildlife is hunkered down for winter. Focus your efforts on damp, humid nights between December and March when temperatures are between 45 and 60 degrees Fahrenheit. If you have a backyard rain garden or a drainage ditch that holds water, place your camera there after a heavy afternoon downpour; the combination of moisture and rising humidity is the perfect trigger for their emergence.

Frequently Asked Questions

Southern Chorus Frogs are primarily nocturnal, meaning they are most active after sunset. They reach their peak activity levels between 7 PM and 3 AM, particularly on rainy or very humid nights.

To attract these frogs, maintain a 'wild' corner in your yard with plenty of leaf litter, fallen logs, and native grasses. Installing a shallow rain garden or a pond that holds water during the winter will provide the essential breeding habitat they look for.

They are insectivores that hunt for tiny prey in the ground cover. Their diet consists of spiders, small beetles, ants, and other invertebrates that live in moist soil and leaf litter.

Yes, they can be quite common in suburbs that have retained some natural drainage. They often utilize roadside ditches, flooded lawn depressions, and backyard ponds for breeding as long as there is cover nearby.

While similar, the Southern Chorus Frog typically has more continuous, well-defined stripes and a slightly more pointed snout. The Upland Chorus Frog often has a dark triangular mark between the eyes and stripes that are frequently broken into small dots.
