The American Bullfrog (Rana catesbeiana -CP)  is the largest of all North American frogs. They can be  found in freshwater ponds, lakes and marshes  with lots of vegetation, especially water lilies. Photograph by D. Greenwood

Bullfrogs are typically green or gray-brown with brown spots and have easily identifiable circular eardrums, or tympanum, on either side of their heads.

Females are slightly larger than the males, but only the male Bullfrog emits the trademark
baritone bellow Click for sounds of american bullfrog calls and their choruses can be heard during the day or night.

Nocturnal predators, Bullfrogs will ambush and eat just about anything they can fit in their  mouths, including insects, mice, fish, birds, and snakes.  Search “Dixie Greenwood” on the top of any page on our site to view more of Dixie’s nature photographs.
