Gray Treefrog_106

Male Gray Treefrog with vocal sac fully inflated while chorusing

Have you ever wondered how loud a frog’s can sing? Well the loudest frog call in the world is that of the Coqui Frog of Puerto Rico, which has been measured at a booming 108 decibels, and that is almost as loud as some jackhammers! The Gray Treefrog of North America has been measured at a range of 88 to 95 decibels. Whenever I have been fortunate enough to be sitting in a wetland at peak chorus with numerous individuals calling all at the same time, the sound can be deafening. In fact the sound level and subsequent ringing in my ears afterwards reminds me of my younger days when I would attend RAMONES concerts 🙂

In these two photos do note the variation in coloration. The frog in the first image is in a shallow pond with a sandy / clay-like bottom and minimal new growth of cattails, hence the drab colors. While in the photo below the pond is much deeper with a dark, mucky bottom and there was significant new growth of cattails, which is why this fella has a brilliant green coloration.
