Bullfrog Habitat
Bullfrogs are one of the most common and prominent amphibians in all of
North America. Originally found only in the eastern part of the North American continent, from Canada all the way
down to Florida, the species now exists – and thrives – in all forty-eight states of the United States and in most
of Canada, as well.
Bullfrogs are among the largest of all frog species and, as is the case for many types of frogs, live in
permanent freshwater habitats. These include a variety of domiciles, everything from ponds, rivers and lakes to
reservoirs, ditches, irrigation canals and more.
Importantly, this species is able to live in both deep and shallow water. American Bullfrogs tend to live a
quiet existence during daytime, when the sun is high in the sky. During these times, Bullfrogs hide under
vegetation, overhanging banks at the water’s edge or they sit and rest in shallow water.
The Bullfrog lives differently after the sun goes down. At night, it hunts all manner of prey and also uses its
“bellowing” call to seek out females. Bullfrogs are good hunters and extremely carnivorous. They will eat virtually
anything they can fit into their mouths.
The American Bullfrog diet consists of insects, small mammals, fish, small birds, bats and more, including other
frogs, eggs and tadpoles. It has amazing leaping ability and a willingness to allow prey to pass before it as it
sits quietly and motionless, two traits that make the American Bullfrog a very successful predator.
Bullfrogs are extremely territorial, as well. An adult male will fight other males that invade its territory
which is generally no more than several yards in total. The fighting consists of a kind of “wrestling.”
Interestingly, during battle, many Bullfrogs will try to gouge one another with their “thumbs.” Some may even
attempt to hold a foe under water (almost like a human being would do), but will eventually release the defeated
foe and allow him to leave the area.
Bullfrogs prefer warm weather and are active primarily in spring and summer. When fall arrives, Bullfrogs
burrow into mud or soft soli to hibernate and remain buried until the arrival of spring. Bullfrogs that live in the
South or warmer Western climates may remain active all year long.
Bullfrogs are universally known for the “croaking” sound they make which they use, of course, to locate other
Bullfrogs, especially females. This bellowing sound is one of the most famous sounds in all of the Animal
Kingdom.
Life is difficult for the Bullfrog, even in its own habitat. It has to fight to survive at every stage. The
struggle begins when it is only an egg, one of 20,000 eggs that have been laid by its mother. The fight moves on to
the next stage when it becomes a tadpole and easy prey for bigger, stronger predators. When the Bullfrog finally
reaches maturity, against all odds, it must fight to protect its territory, fight to capture prey and fight to live
out its lifespan, a period thought to be somewhere between 4 to 5 years, somewhat longer in warmer climates.
