Common Name: Oak Toad
Scientific Name: Anaxyrus quercicus
Family: Bufonidae – True Toad Family
Locations: United States – Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, and Virginia
Size: 1.25 inches max

The Oak Toad is the smallest toad in North America, not even reaching 2 inches when it is fully grown. They are also interesting in the fact that they are mostly diurnal, active during the day, while most true toads in North America are nocturnal, active during the night.

Breeding takes place from April to September, depending on the arrival of the heavy, warm rains. The mating call of the males sound like baby chickens. While the Oak Toad is small, the female can lay up to 700 eggs. Tadpoles hatch from their eggs in a day and fully undergo metamorphosis in a month or two.

least concern
Common Name: Green Toad, North American Green Toad
Scientific Name: Anaxyrus debilis
Family: Bufonidae – True Toad family
Locations: Mexico and the United States
US Locations: Arizona, Colorado, Kansas, New Mexico, Oklahoma, and Texas
Size: 1.4 inches

The North American Green Toad is found in the south-central United States and down to Mexico. It is often called just the Green Toad but that often leads to confusion with the European Green Toad (Bufo viridis). There are two subspecies of North American Green Toad that are recognized today, the Western Green Toad (Anaxyrus debilis insidior) and the Eastern Green Toad (Anaxyrus debilis debilis). 

Breeding takes place during or after the summer rains come. When these rains arrive from Match to June, depend on location. As explosive breeders, the Green Toad generally only takes a few days to breed in temporary ponds filled by the summer rains. These ponds are free of some of the common predators of the toad’s eggs and tadpoles such as fish. They make amazing breeding sites besides the fact that they will eventually dry up.
