Are there tree frogs in Alaska rivers?
Yes, but only one species calls Alaska home: the Pacific tree frog (*Pseudacris regilla*). It thrives in the coastal rainforests of Southeast Alaska, where rivers, streams, and wetlands provide ideal breeding habitat. While not abundant statewide, they are most likely heard than seen along river corridors from Ketchikan to Juneau.

What rivers in Alaska have the best chance of spotting tree frogs?
Your best odds are along slow-moving rivers with adjacent ponds and marshy banks. Top picks include the **Stikine River** near Wrangell, the **Taku River** near Juneau, and the **Chilkat River** near Haines. These rivers have extensive floodplains and backwaters where Pacific tree frogs breed in spring. The rivers of the Tongass National Forest offer the most consistent sightings.
When is the best time to hear tree frogs along Alaska rivers?
The breeding season from **late April to early July** is your window. Males call day and night to attract mates, with peak activity after warm spring rains. Early morning and dusk are prime listening times. Once summer heats up, frog activity quiets as they move back into forests.
How can I identify a tree frog in an Alaska river habitat?
Pacific tree frogs are small (1-2 inches) with smooth skin, a dark stripe through the eye, and large toe pads for climbing. Their call is a sharp two-note *kreck-ek* or a trill, often described as a duck-like quack. Look for them clinging to vegetation along riverbanks or floating on pond edges near rivers.
