Dense tropical forests on Hawaii Island are often home to invasive Coqui frogs.

It's a noisy wilderness out there.

In Hawaii

The coqui frog was accidentally introduced to Hawai'i from Puerto Rico around 1988. Not only are Coqui Frogs a major noise nuisance, but they also pose a threat to all of Hawaii's ecosystem.


According to the University of Hawaii at Manoa, "Coqui frogs have a voracious appetite that puts Hawai'i’s unique insects and spiders at risk. They can also compete with endemic birds and other native fauna that rely on insects for food. The frogs are quite adaptable to the different ecological zones and elevations in the state and have been found from sea level to 4,000 feet elevation (at sites in Volcano on Hawai'i). Scientists are also concerned that an established coqui frog population may serve as a readily available food source if (or when) brown tree snakes are accidentally introduced in Hawai'i."

The presence of Coqui in Hawaii is growing and Coqui frog eggs can quickly create overpopulation. One adult female can lay "more than 1,400 eggs per female per year" according to the College of Tropical Agriculture and Human Resources, University of Hawai'i at Manoa.
