Tree Frogs in Hawaii: Identification Guide and Best Places to Start
Yes, tree frogs live in Hawaii, but they're not native. The coqui frog (Eleutherodactylus coqui) is the most common species, introduced from Puerto Rico. You'll hear their two-note call at night in moist forests. Start your search on the Big Island or Maui in rainy areas.

1. Where are you most likely to see tree frogs in Hawaii?
Tree frogs, especially the coqui, are most common on the Big Island and Maui. Look for them in damp, shaded areas like gardens, forests, and near streams. They hide under leaves, in banana plants, and around building foundations. On the Big Island, try the Hilo side or Volcano Village. On Maui, the eastern slopes near Hana are prime territory. Check outtree frog habitatsfor more specific spotting tips.
2. What time of year or weather conditions help with spotting?
Coqui frogs are active year-round in Hawaii, but they are easiest to hear and see after rain or during humid nights. The wet season (November to March) increases calling activity. Evening and early morning hours, especially after a shower, offer the best odds. During dry spells, they stay hidden in moist microhabitats.

3. How can you identify a coqui frog from other small frogs?
The coqui frog is small, about 1-2 inches long, with a brown or gray body that may have a faint stripe. Its most distinctive feature is its call: a loud two-note "ko-KEE" that gives it its name. Native Hawaiian frogs are absent, so any calling frog at night is likely a coqui. Unlike the green tree frogs found on the mainland, coquis are usually brown.

4. What does the coqui frog sound like?
The male coqui frog sings a two-part call: a short "ko" followed by a rising "KEE". It is one of the loudest frogs for its size, often reaching 80-90 decibels. Chorus can be overwhelming in infested areas. Listen for it at dusk and throughout the night. If you hear it, you are likely near a population. For reference, check recordings online or use a frog call app.
5. Are tree frogs invasive in Hawaii?
Yes, coqui frogs are an invasive species. They arrived in the late 1980s via plant shipments from Puerto Rico. They have no natural predators here and reach high densities, which disrupts the ecosystem and creates noise pollution. The state and local groups work to control their spread. If you see one, report it to the Hawaii Department of Agriculture. Learn more aboutHawaii's invasive species.
6. What gear or apparel can help you enjoy tree frog spotting?
For nighttime frog spotting, a red flashlight minimizes disturbance. Wear closed-toe shoes and long pants to protect against mosquitoes and sharp plants. A light rain jacket is handy for wet nights. If you want to show your appreciation for these vocal amphibians, consider these options:
