Tree Frogs in Hawaii: identification guide and best places to start

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.

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.

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.

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.

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.
