The Eastern Narrow-mouthed Frog is one of the smallest Kentucky frogs. A huge one may reach 1 1/2 inches, but most are smaller. An Eastern Narrowmouth has a round chubby body, very short stubby legs, and a pointy little head set off by a fold of skin across the nape of the neck. These frogs can be gray, brown, or reddish-brown above, darker along the sides, with or without a sizeable dark outline in the center of the back.
These curious little frogs can be found across southern and western Kentucky in a variety of habitats ranging from mature forests to overgrazed pastures, rocky glades, abandoned quarries, gravel pits, and surface mines. They call and breed from late May through early August in wet grassy meadows, roadside ditches, and small ponds. Narrow-mouthed Frogs will often call by day just after a summer rain. Males hide under the grass and are very hard to find when calling; the voice is an angry buzzing bleat and sounds like the call of an undersized Fowler's Toad.
