Are There Bullfrogs in New York?
Yes, bullfrogs are common and widespread throughout New York State. They are native to New York and thrive in countless freshwater environments, from Long Island's coastal wetlands to the Adirondack region and western lakes.

Where Bullfrogs Are Found in New York
Bullfrogs are found throughout New York in virtually all suitable freshwater habitats. In Long Island, they occupy the numerous marshes, ponds, and brackish wetlands. The Hudson River valley supports abundant bullfrogs in its tributary streams, ponds, and associated wetlands. The Finger Lakes region, with its deep glacial lakes and surrounding marshlands, has useful bullfrog populations. The Adirondacks support bullfrogs up to moderate elevation where permanent water exists. Lake Champlain and its shoreline wetlands harbor significant bullfrog populations. Cayuga Lake, Seneca Lake, and other major Finger Lakes have established bullfrogs. The Genesee River and its flood plain wetlands in western New York contain bullfrogs. In central New York, Onondaga Lake and Oneida Lake support bullfrog populations. The Mohawk River valley has bullfrogs in suitable sections. Nearly every permanent pond, marsh, and slow river section in the state contains bullfrogs. TheNew York wildlife guideprovides detailed information about habitats throughout the state. Bullfrogs are absent only from cold mountain streams and rapidly flowing rivers without slack water or vegetation. Seethe Bullfrog guide for New Yorkfor more.
Season and Timing in New York
Bullfrogs in New York follow a distinct seasonal cycle tied to temperature and daylight changes. They emerge from winter dormancy in April and May as water temperatures rise above 50 degrees Fahrenheit. Initial activity is modest, with scattered calling in late May. Peak breeding season extends from June through August, when male bullfrogs vocalize nightly from sunset through dawn. July and August are the loudest months, with choruses of hundreds of males calling from many water bodies. Tadpole metamorphosis occurs from July through September, with young froglets leaving water during late summer. By October, calling activity decreases substantially as water temperatures cool. In November and December, bullfrogs retreat to deeper water and hibernacula, entering dormancy. They remain inactive throughout winter, hidden in mud, under rocks, or in deeper water where temperatures stay above freezing. This winter dormancy is essential for surviving New York's cold winters. Spring emergence timing varies by latitude and elevation, occurring earlier in southern New York than in the mountains. The entire active season spans approximately seven months, with three months representing peak reproductive activity.
How to Identify a Bullfrog
Bullfrogs are the largest frogs in New York, typically reaching four to eight inches in body length, with exceptional individuals exceeding eight inches. Their skin is smooth and glossy, usually green or olive green with variable darker mottling across the back and sides. The underside is pale yellow or white, often with darker bars or blotches, particularly visible on the belly and legs. The most distinctive feature is the large, prominent tympanum or ear, a circular area of membrane visible just behind the eye on each side of the head. Males have tympana considerably larger than their eye diameter, while females have tympana roughly equal to eye size. A prominent fold of skin runs along each side of the head from behind the tympanum. The hind legs are large and muscular, and the feet are fully webbed. During breeding season, males develop darkened coloration and thickened arms. Tadpoles are large and greenish, growing to several inches in length. No other frog in New York is as large as the bullfrog. Learn aboutNew York's amphibiansto understand how bullfrogs fit into the state's ecosystem.
Where Sightings Concentrate in New York
Bullfrogs concentrate in specific habitat types throughout New York where conditions are most favorable. Cattail marshes bordered by shallow water one to three feet deep are prime bullfrog habitat. The Montezuma National Wildlife Refuge in central New York is one of the state's richest bullfrog areas, with thousands of calling males during breeding season. Iroquois National Wildlife Refuge near Buffalo supports abundant bullfrogs. The Tonawanda Swamp and other large wetland complexes in western New York have high bullfrog densities. Freshwater marshes along Long Island's north shore, such as those in the Great Neck area, harbor bullfrogs. Beaver pond systems in the Adirondacks and throughout forested regions support bullfrogs when permanent water is present. Shallow coves and marshy shorelines of large lakes like Oneida, Onondaga, and the Finger Lakes concentrate bullfrogs. Oxbow lakes and abandoned quarries that have filled with water often become excellent bullfrog habitat. Vernal pools that retain permanent water support bullfrogs. The most productive areas combine shallow water, emergent vegetation, and nearby upland cover. Visit thewildlife guideto find other wetland species that share bullfrog habitat throughout New York.
Typical Bullfrog Behavior
Bullfrogs are solitary and territorial animals, especially males during breeding season. They are primarily nocturnal, hiding under vegetation or submerged objects during daylight hours. At dusk, males move to calling sites in shallow water or along shorelines. They inflate their vocal sacs to produce the loud, resonant jug-o-rum call that is the defining sound of New York summer wetlands. This call attracts females and warns rival males. Males defend small territories vigorously, sometimes engaging in wrestling matches with intruding males. Bullfrogs are ambush predators, remaining nearly motionless until prey approaches. They eat insects, spiders, crayfish, other frogs, small snakes, and occasionally young birds or small rodents. Adults readily consume smaller frog species and their own tadpoles. Females remain silent and are attracted to calling males. Mating occurs at night in shallow water, with females laying gelatinous egg masses containing up to 20,000 eggs. Tadpoles are aquatic omnivores, eating algae, detritus, and small organisms. Metamorphosis takes two to three years in New York, making bullfrog tadpoles long-lived residents of water bodies. Bullfrogs are strong swimmers and skilled at escaping predators.
Coexistence and Legal Status in New York
Bullfrogs are native to New York and fully protected under state wildlife laws. There are no legal restrictions on protecting or observing wild bullfrogs. Some areas have regulated harvest seasons for bullfrog legs, considered a delicacy in certain communities. Check current New York Department of Environmental Conservation regulations before attempting to harvest any wildlife. Bullfrogs pose no danger to humans. They are not venomous and their calls, while loud, cause no harm. Bullfrogs are sometimes viewed with mixed feelings because they are voracious predators that consume native frogs and their tadpoles. In some conservation contexts, bullfrogs are considered problematic in certain water bodies. However, they are widely tolerated as established members of New York's wildlife group. In the Adirondacks and other sensitive areas, bullfrogs are simply part of the ecosystem. No widespread management programs target bullfrogs in New York. If you encounter a bullfrog, approach slowly and quietly. The animal will typically retreat into water if threatened. Bullfrogs generally ignore humans unless directly captured or confined.
Species Often Confused with Bullfrogs
New York has several frog species, and some can be confused with bullfrogs by untrained observers. The Green Frog is the species most commonly mistaken for a juvenile bullfrog. Green Frogs are smaller, typically two to four inches long, with a prominent ridge running along each side of the back. The American Toad is common throughout New York but is clearly different, with warty, bumpy skin and a stubby build. Leopard Frogs occur in some areas and have rounded spots rather than mottling. Peeper frogs and other tree frogs are much smaller and different in appearance. The Pickerel Frog has a pattern of rectangular spots arranged in rows, distinct from the bullfrog's pattern. Eastern Gray Tree Frogs are small and tree-dwelling with adhesive toe pads. The Spring Peeper is tiny compared to bullfrogs. Most confusion occurs between bullfrogs and large Green Frogs, but the bullfrog's substantially larger size, larger tympanum, and more useful build make distinction possible with careful observation.
Frequently Asked Questions About Bullfrogs in New York
