ENVIRONMENT REPORT -May 31, 2002: Coqui Frogs Invade Hawaii


This is the VOA Special English ENVIRONMENT REPORT.


Experts say the American state of Hawaii has been invaded by a small frog called the coqui (ko-KEE). There may
be millions of the small frogs in Hawaii. However, they do not belong there. They are normally found in the
Caribbean island of Puerto Rico and in the southeastern United States. The coqui frogs are harming Hawaii’s


environment. And the extremely loud noise they make is causing problems for Hawaiian citizens and visitors.



The coqui invaders 1 arrived in Hawaii about ten years ago. They were believed to have been
brought in accidentally in shipments of plants from Puerto Rico or Florida. Their numbers have
sharply increased. They have quickly spread around the Hawaiian Islands hidden in plants.


The coqui is a brown frog about five centimeters long. During the day, the frogs hide in wet
protected areas, such as under plant leaves. At night, the frogs move onto trees to feed, call to


females and mate.


In their native Puerto Rico, local people celebrate coqui frogs. But in Hawaii, the foreign frog has been
condemned 2 as a harmful animal.


The coqui frogs are a major threat to Hawaii’s environmental system. The frogs eat thousands of insects every
night. These insects are important for the reproduction of plants. The insects also are important food for
Hawaii ’s native, rare birds.


The frogs also are affecting the tourism industry in Hawaii. Increasing numbers of hotels, visitors and local
people have protested about the loud calls made by male coqui frogs to female frogs. At night, the noise often
makes it difficult for people to sleep. The mating call of the male coqui sounds like: “Ko-Kee! Ko-Kee!

That
is how they got their name.


The frogs do not have any natural enemies in Hawaii to reduce their population size. The warm weather permits
them to lay eggs all year long.There are many efforts in Hawaii designed to stop the spread of the coqui. It is a
crime to transport, sell or release the frogs there.


The Hawaiian Department of Agriculture is trying to find an effective chemical that can be safely used to kill the
frogs. For now, the frogs may only be captured by hand. The Hawaiian Department of Agriculture says the
greatest threat to the economy and environment of the state is from harmful invasive species, like the coqui.
