Tree Frogs In Pa

In Pennsylvania, there are only 7 species of tree frogs out of approximately 800 species worldwide. Technically speaking, a tree frog is not one that lives in trees. The ability to climb trees is provided by a claw-shaped bone and unique toe pads in the toes of real tree frogs. These toe pads have been lost by species that dwell below earth.

There are 16.8 million acres of forest area in Pennsylvania, and several animal species call these regions home. Pennsylvania also boasts more than 4,000 lakes, reservoirs, and ponds in addition to 83,184 miles of streams and rivers.

After all of that, let’s have a look at the tree frogs of Pennsylvania!

Western chorus frogs start singing early in the year, frequently before the ice has melted, and they reproduce close to water sources. One to two seconds pass during the call, which is repeated multiple times. From February through June is the breeding season.

They consume larvae of insects as well as other tiny invertebrates.

Green Frog

The Northern Green Frog is a very aquatic species that is widespread in Pennsylvania. This frog inhabits streams, bogs, rivers, and other bodies of water, preferring to dwell near shallow water. The species is quite active. Most of the time, it will venture out at night, but on occasion, it will forage during the day.

Wood Frog

In Pennsylvania’s vernal pools, a species of wood frog that is extensively dispersed over North America, is found. It is renowned for its great frost resistance and terrestrial nature. Long-distance migrants, this species may also be found in freshwater marshes, ravines, and other habitats on the uplands.

Adults migrate to the wooded areas during the summer to hibernate. One of the first species to appear after the snow melts is the wood frog.

It is a tiny frog that comes in many tones of brown, tan, and rust. It has a distinctive appearance with black markings that surround its eyes and continue to its snout. It has a green, white, or yellow stomach. Its appearance aids in blending with leaf litter, and its quick, lengthy jumps aid in hiding in the vegetation.

The food source for wood frogs is insects, and they hunt often. They will pursue after prey while having their mouths open and sticking out their tongue and jaw. Due to its resilience to freezing, it remains active for longer periods of time.

This species may be found on land or in water, and it has a thriving population. Some populations have been dispersed by urbanization, and this species depends heavily on wetlands for reproduction.
