Tree Frogs Sounds

Have you heard a frog calling from your back yard? Did you hear a call coming from the grass along the riverbank while on a walk?

There are 32 tree frog species in the United States. Continue reading to help you identify which tree frog sound you are hearing or heard.

How Do Tree Frogs Make Noise

Tree frogs are able to make sound by allowing airflow to go via the lungs, past the larynx, and into the mouth, causing the vocal cords to osculate. The vocal muscles can make up fifteen percent of a frog's body mass.

The sound is made from air sacs, which are located just below the mouth. You can see these sacs inflating and deflating as the frog makes a sound.

The air from the lungs is channeled into their air sacs, making the sound louder.

These frogs produce two types of cells that scientists focus on they are used when making mating and releasing calls.

When the male and female are mating, the male produced what is known as a release call. Their body walls contract, causing the inter pulmonary pressure to increase. The glottis opens to allow airflow to pass via the larynx and then the vocal cords oppose each other, as a result, the airflow causes the vocal cords to vibrate.

Why Do Tree Frogs Make Noise

Frogs can make sound for a number of reasons, they are not only used for attracting a mate. They are known to make warning, release and distress sound, along with territorial sound.

Territorial Sounds

Male frogs are known to make territorial calls to inform other frogs that there is their territory, encouraging any intruders to move away.

These often sound more like a groan and differ from the mating call.

The aim is to ensure other frogs know their presence.

Distress Sounds

Distress calls are awful and dramatic sounds that are made by a tree frog when it is attacked by predators.

They are almost like a high-pitched scream, startling the predator, which can result in the predator releasing the frog, giving it a chance to escape. These sounds are distressing to hear and a sign of panic.

Warning Sounds

Warning sounds are used when the tree frog is disturbed or startled. It sounds like a short squawk or grunt, made as the frog jumps away. This often alerts other frogs in the area that there could be a danger.

The sounds are similar to what humans make when you get a surprise, an exclamation noise.

Release Sounds

Release sounds are the noise a tree frog makes if it is grabbed by another frog while searching for a mate.

When frogs are unsuccessful at finding a mate, they often grab and hold onto any frogs that move past them. Release calls are used by male frogs, females that have already mated, and different species frogs to let the frog known that he is wasting his time.

This sound is similar to a chicken clucking, which is also made by tree frogs if you hold them too tight.

Only male frogs make territorial and mating calls, while males and females can make distress, warning and release calls.
