|wood frog ( NYS Dept. Environmental Conservation)
A layer of leaves sounds cozy - but it's not nearly warm enough to keep the frogs from freezing. So it's a good thing these frogs have "antifreeze" in their system.
Meanwhile, during these last nights of summer, the woods around my house is noisy. Every evening there is a symphony of cricket and frog song that echoes through the trees.
What sort of night sounds do you have around your home? Open the windows and listen. See if you can tell who's singing/chirping/wailing/trilling. If there are too many human sounds, take a nighttime field trip to a park where you can hear the insects and last-of-summer amphibians. You can listen to the sounds of frogs here and here.
