The Kutenai, Flathead and Rappahannock are reported to have consumed frogs [1, 2].
The Rappahannock caught frogs by hand; hunters lured them at night to a stream or marsh bank with a small flame or hot coal.
Although frogs were not eaten by Yukon Athapaskan First Nations, a story describes a group of children who were thought to have offended a frog which they believed caused the subsequent year of starvation [3].

Frogs, like toads, are members of a large group of amphibians referred to as the anurans, which means ‘tailless’. As all amphibians, frogs begin their lives in water as legless, gill-breathing, vegetarian tadpoles with a long paddle-like tail before growing into tailless, long-legged, lung-breathing, carnivorous adults that can remain on land most of the time. In North America, frogs are represented by many families, including the true frog family with many species that are familiar in and around ponds and lakes, like the American bullfrog (Lithobates catesbeianus), the green frog (L. clamitans), the northern leopard frog (L. pipiens), and the wood frog (L. sylvaticus).
