1. Hilo, Big Island

The Hilo area on the Big Island is one of the most prominent locations for coqui frogs. Their loud 'ko-kee' call is a constant nighttime sound in many residential areas and forests. While they are difficult to see due to their small size and camouflage, you can easily hear them throughout the evening. It is a major area for coqui frog activity.

2. Lawai, Kauai

On the island of Kauai, the Lawai area has become a known location for coqui frogs. They are often found in lush, tropical vegetation where they find plenty of insects to eat. Local conservation efforts are active in this area to monitor and manage the population. It is a place where you can experience their distinctive calls firsthand.

3. Haiku, Maui

The Haiku region on Maui is another area where coqui frogs have established themselves. The wet, tropical climate is ideal for these small tree frogs. They are most active at night, especially after a rain. While they are considered an invasive species, they have become a part of the nocturnal soundscape in this part of the island.

4. Manoa Valley, Oahu

Manoa Valley on Oahu, with its frequent rainfall and lush gardens, is a place where greenhouse frogs (another introduced species) are common. While not as loud as the coqui, their chirping calls can be heard in the evenings. They are often found in residential gardens and along forest edges throughout the valley.

5. Foster Botanical Garden

The Foster Botanical Garden in Honolulu is a great place to see a variety of introduced frogs and other wildlife in a managed setting. The garden's diverse plant collections provide habitats for species like the greenhouse frog. It is an accessible location for families to learn about Hawaii's introduced amphibians and their role in the environment.

How to plan a realistic Hawaii frog trip

A good Hawaii frog plan involves listening for their calls at night, especially in wet and tropical areas. Most tree frogs in Hawaii are nocturnal and very small, making them difficult to spot during the day. Focus on areas with lush vegetation and plenty of moisture. Use theHawaii wildlife hubfor more location ideas.

When is the best time to hear frogs in Hawaii?

Frogs in Hawaii are active year-round due to the warm climate. However, they are most vocal and active on warm, humid nights, especially after a recent rain. The peak of their calling activity typically occurs during the early evening hours and continues throughout the night in areas with high populations.

Are frogs in Hawaii a problem?

Yes, introduced frogs like the coqui are considered a major invasive species problem in Hawaii. Their extremely loud calls can be a nuisance to residents, and they compete with native birds and insects for food. They also have no natural predators in Hawaii, allowing their populations to grow rapidly in some areas.

What should I do if I find a coqui frog in Hawaii?

If you find a coqui frog on an island where they are not yet established, or in a new area, you should report it to the Hawaii Department of Agriculture or the local invasive species committee. They work to monitor and manage these populations to protect Hawaii's unique native ecosystems and the quality of life for residents.
