Alabama is home to a diverse array of frog species, each with unique characteristics and ecological roles. Whether you’re a nature enthusiast, a student, or just curious about the amphibians in your area, this list offers a detailed look at the most common and notable frogs found across the state. Discover the variety of frogs that call Alabama home and learn what makes each one special.
American Green Tree Frog (Hyla cinerea)
The American Green Tree Frog is easily recognizable by its vibrant lime-green color and small size, typically around 1.5 to 2 inches long. It prefers moist, arboreal habitats like trees, shrubs, and wetlands, often seen perched during the evening. Its distinctive call—a series of short, musical notes—can be heard during warm, humid nights, making it a favorite among frog watchers.
Southern Chorus Frog (Pseudacris nigrita)
The Southern Chorus Frog is a small, brown or gray frog with dark markings that help it blend into leaf litter and grassy areas. It’s known for its loud, repetitive call that sounds like a high-pitched trill, especially during the breeding season in spring. Found in open woodlands, marshes, and roadside ditches, it plays a vital role in controlling insect populations.
Greenhouse Frog (Eleutherodactylus planirostris)
Originally from the Caribbean, the Greenhouse Frog has established populations in southern Alabama. It’s a tiny frog, about 0.75 inches long, with a brown or tan coloration and a distinctive dark marking on its back. This species is often found in moist, sheltered areas like gardens, basements, and greenhouses, and it’s notable for its direct development—skipping the tadpole stage entirely.
Pickerel Frog (Lithobates palustris)
The Pickerel Frog is a medium-sized frog, typically 3 to 4 inches long, with a distinctive pattern of rectangular, dark brown or black spots on a yellow or greenish background. It prefers cool, clear streams, ponds, and wetlands, where it feeds on insects and small invertebrates. Its skin secretes toxins that deter predators, making it a fascinating species to observe.
Wood Frog (Lithobates sylvaticus)
The Wood Frog is famous for its remarkable adaptation to cold climates, often seen in deciduous forests across Alabama. It has a brown or reddish coloration with a distinctive dark mask across its eyes. During winter, it hibernates under leaf litter or within soil, and it’s known for its early spring breeding calls that resemble a snore or cluck.
Southern Leopard Frog (Lithobates sphenocephalus)
This large, robust frog measures about 3-4 inches and features a green or brown body with irregular, dark spots that resemble a leopard’s pattern. It inhabits a variety of wetland habitats, including ponds, marshes, and ditches, and is often active during the day as well as at night. Its cheerful, musical call is a common sound in Alabama’s wetlands during the summer months.
Pig Frog (Lithobates grylio)
The Pig Frog is a sizable species, reaching up to 5 inches in length, distinguished by its loud, pig-like grunts. It has a green or brown coloration with a robust body and prominent tympanum (ear drum). Found in large ponds, lakes, and slow-moving rivers, it is often heard during the warm months, especially at dusk and night.
Barking Tree Frog (Eleutherodactylus augusti)
This species, slightly smaller than the American Green Tree Frog, is known for its distinctive barking call that can echo through wooded areas. It has a smooth, green or brown body with subtle markings, and it often hides in tree bark or dense foliage. Its presence indicates healthy, moist forest ecosystems in Alabama.
Pickerel Frog (Lithobates palustris)
The Pickerel Frog is a medium-sized amphibian, about 3-4 inches long, easily identified by its bold, rectangular black spots on a yellow-green background. It favors cool, clear streams, ponds, and wetlands, where it feeds on insects and small invertebrates. Its skin secretes toxins that serve as a defense mechanism against predators, making it a fascinating species to observe in the wild.
How to Choose
When selecting a frog to observe or study, consider factors like habitat preference, size, coloration, and call. Think about the environment you have access to—are there wetlands, forests, or ponds nearby? Listening for calls during breeding season can also help identify specific species. Additionally, understanding each frog’s activity patterns—day or night—can enhance your chances of spotting them.
Frequently Asked Questions
Are all frogs in Alabama poisonous?

How can I attract frogs to my backyard?
Creating a pond with native plants, avoiding chemicals, and maintaining moist, shady areas can encourage frogs to settle in your yard. Providing logs or rocks for shelter also helps.
Are frog calls a good way to identify species?
Absolutely. Many species have distinctive calls that are useful for identification, especially at night or in dense vegetation where visual spotting is difficult.
Can I keep frogs as pets?
While some frogs are kept as pets, many native Alabama species are best appreciated in their natural habitats. Always research local laws and ensure proper care if keeping frogs as pets.
