(Pseudacris triseriata)
The Chorus Frog can be found calling within the Archaeology Pond and Archaeology Marsh in the early spring, around the end of April and the begining of May. This is one of the first species to begin calling in the spring. Along with the Spring Peeper, the Chorus Frog calls following the Wood Frog. However these species often overlap, and all three species could begin their calls at the same time, depending on the temperatures in the spring.
It is very difficult to find a male or female of this species. They are very small, ranging in size from 1.9-3.9 cm. If you do think you have found one, it can be identified by the brown-green colour covering its body. Three dark broken stripes flow down the back of the animal, with blotches around each leg.
This species’ call is described as being similar to the sound one would make if they ran their finger along a plastic comb. The males can often be heard calling at the same time as the Spring Peepers. When frogging in the spring of 2001, I found that there were not as many Chorus Frogs in the Marsh or Pond, as there were Spring Peepers. This makes it difficult to find a Chorus Frog. In addition to their small size and less numbers, this species is difficult to find because they are very cautious about calling when humans are ‘making waves’ around their area by walking. Too find one you must listen for where the call is located, and then slowly approach the site by making frequent stops to deter the frog from jumping away.
