These warm spring evenings bring out familiar sounds. The most distinctive one is the call of the male spring peeper, which reminds some of crickets chirping. At less than an inch and a half long, spring peepers are the tiniest frogs in North America. They can be tan, gray or dark brown, but all have a dark “X” on their backs. These amphibians also have toe pads that grip like suction cups for climbing.
Abundant in our swamps and other wet wooded areas, these critters are rarely seen. Many of you have steamrolled them with your vehicles on rainy evenings, but other than that you might not have noticed them. They’re nocturnal and pretty well camouflaged. They eat mostly insects and spiders, which I’m sure is fine with most people. It’s a shame so many wind up under our tires.
The American toad is another amphibian that rings in spring. The call of these rough-skinned creatures is a high pitched trill. Each blast sometimes lasts a half minute. Toads can occasionally weigh over a pound and have been known to live for thirty years. Females are usually much larger than males.
They are insect eating machines, feasting on mosquito larvae and other insects. They also eat earthworms, snails, slugs, fish and just about anything else that fits into their mouths. Since toads are slower than most of their jumping relatives, one might expect them to be easy prey for other animals. Generally they are not. Toads have special structures called paratoid glands, which produce a foul-smelling, toxic chemical. For this reason it’s wise not to pick them up, but don’t worry. Toads don’t give you warts.
Many consider toads welcome guests to their gardens. This is generally true, but I once had a swimming pool and they would breed and fill the water with ropes of eggs that hatched into tadpoles. If their breeding season were later in the year the warty devils likely would have chosen a different spot, but an unopened pool doesn’t have the deterrent of strong chlorine. For a month or two out of the year they were not my friends, but that doesn’t mean I avoided all amphibians.
The bullfrog is the largest frog in North America. Bullfrogs are solitary and very territorial. They rarely meet, except to fight over territory or mate. Their distinctive croaking is music to my ears.
Bullfrogs have voracious appetites. They eat insects, crayfish, earthworms, fish, other frogs (especially leopard frogs, but even other bullfrogs), small turtles, snakes, baby birds, mice and voles. They are most active at night. Their skin contains glands which secrete substances that render them unpalatable to predators, so most mammals leave them alone.
Remove the skin and their legs are a delicacy. The pale pink flesh is similar to chicken tenderloins, but clean them up thoroughly or they have a bitter fishy flavor. Whether you like yours fried with breading and Cajun spices or grilled with a little lemon, butter and garlic they are truly a spring treat which lasts through summer.

Heard the first Peepers in February this year…highly unusual!
Thanks for a great post – we love all our froggies and their relatives.
i used to catch these when i was younger,but now when i look at them i regret touching one. they can be annoying after a while to
i also used to touch these wen i was little, but now looking at how i am now its unbelievable that i even went near them. theyre interesting to learn about but i never wanna touch them.
my little sister has a bullfrog that she caught when last summer hes gotten huge but he only likes to eat the worms she gives him. they are very neat to learn about but I hate when they are around me simply cause I don’t like slimy things.
