Grey Treefrogs (Hyla versicolor) are my favorite frog species at the moment. They are cute little colour changing, antifreeze laden, Lichen-Spirits who really belt it out when trying to find a date. I have been hearing them pretty much nightly lately, screaming their short trill all over nearly every wetland I encounter as long as it is fairly adjacent to trees. Because of their powerful calls permeating my late night waking life, I have been wanting to take a deeper dive. Hope you enjoy!
