Unfortunately, these little stowaways were not warmly received by the Alaska Department of Fish and Game. They are considered invasive species as they might carry fungi and viruses that could harm native frog species.

According to Lang Elliott in The Frogs and Toads of North America, its familiar two-part call, rib-bit, is the one most associated with frogs because they have provided the background “music” for so many Hollywood movies and TV shows.

Here’s the call of the Pacific Chorus frog in its native habitat—far from Juneau.
