The Frog That Makes Pocket Comb Music


Western Chorus Frog

After my poetry post, my team and I split up to do our own posts about our sit spots. We went out in the woods and picked a spot that we became accustomed to. We spent four sessions in our sit spot observing what nature had to offer. It was on the last sit spot that I unlocked the mystery of the animal that makes the “creeek” sound.

This frog is call the Western Chorus Frog. The frog is the reason that you hear a noise that sounds something like someone is strumming a pocket comb. The frog’s scientific name is pseudacris triseriata triseriata.  Click here to listen to it’s call. Western Tree Frogs usually live to be about 15 years old. Although most die when they are tadpoles or froglings. They can have up to 500 to 1500 eggs. Western Chorus Frogs are preyed upon by many things. Including large birds, small mammals, and snakes. However tadpoles and froglings are the targets for other frogs, crayfish, fish, turtles, and dragonfly larvae.  These types of frogs usually live in woodsy areas, wetlands, and marshes.

They are about 1.6 inches long. 40mm for you metric system fans(I mean you Mr. Long).  The one I saw had greenish-grey skin but they can come is reddish, olive, or brown skin tones. The males are usually smaller than the females. You can tell if it a female because females have yellow vocal sacs.

The tadpoles of Western Chorus Frogs are green or brown. The body is round, has clear tail fins, and has dark flecks. Apparently you can see the intestinal coils though the transparent body if you look close enough. Tadpoles lips are black.

Usually these frogs only come out in the night so it was a little bizarre to see one in broad daylight. But when they come out they usually start their chorus or they feed. Frogs feed on things like small flies, mosquitos, small spiders, and other small insects. Froglets(when they are in the stage between tadpoles and adult frogs) feed on smaller prey. This can include mites, midges, and springtails. And tadpoles will feed on pollen, algae, and other aquatic things.
