What tree frog species are found in New Hampshire?
New Hampshire hosts three tree frog species: the **gray tree frog** (_Hyla versicolor_), the **spring peeper** (_Pseudacris crucifer_), and the **boreal chorus frog** (_Pseudacris maculata_). The gray tree frog is the most frequently encountered and can appear gray, green, or brown. Spring peepers are tiny (1 inch) with a distinctive dark X on their back. Boreal chorus frogs are slightly larger with three dark stripes down their back. All three are true tree frogs with toe pads for climbing.

How can you identify a tree frog in New Hampshire?
Start with size and toe pads. Gray tree frogs (1.5-2 inches) have large toe pads and rough skin. They can change color gradually. Spring peepers are smaller (0.75-1.25 inches) with smooth skin and a dark X on the back. Boreal chorus frogs have three dark stripes and a white upper lip. The most useful ID marker is the call: gray tree frogs produce a short, musical trill; spring peepers give a high-pitched 'peep'; chorus frogs make a sound like running a finger over a comb.

Where in New Hampshire do people most often spot tree frogs?
Tree frogs are most common in southern and central New Hampshire. Good bets include the **Merrimack River Valley**, **Lake Winnipesaukee** shoreline, and **White Mountain National Forest** edges near wetlands. They cling to branches and leaves overhanging ponds, swamps, and slow streams. Listen for calls after dusk from May to July. Suburban backyards with small ponds also attract them, especially gray tree frogs.
Start with local ponds or visit theNew Hampshire wildlife pagefor specific hotspots.

When is the best time of year to see tree frogs?
The peak season is **mid-May through late June**, when breeding calls fill the air. Warm, humid nights are best. Spring peepers begin calling as early as March, but tree frogs are most active when night temperatures stay above 50°F. Daytime sightings are rare; look for them resting on leaves or sides of houses after rain. The best odds occur within two hours after sunset during a light rain.

What are common lookalikes to tree frogs in New Hampshire?
The **northern leopard frog** and **wood frog** are often mistaken for tree frogs. Leopard frogs have spots and live on the ground. Wood frogs have a dark mask and prefer forest floors. Neither has large toe pads for climbing. Gray tree frogs can also look like lichen or bark when resting. The best separation: tree frogs always have toe pads, and their skin is slightly rougher than other New Hampshire frogs.

How do tree frog calls help with identification?
Calls are the most reliable way to identify tree frogs without seeing them. Gray tree frogs make a **clear, musical trill** lasting 1-2 seconds, often repeated every few seconds. Spring peepers produce a single high-pitched 'peep' that sounds like sleigh bells. Boreal chorus frogs make a **stiff, ascending 'creeeeek'** that rises in pitch. Use a field recording app to compare calls. Hearing the call immediately tells you which species is present.
