Last look at fall frogs

Posted

Green frogs are likely to be the most abundant species you will find in a lake or pond. Their call can be heard from late spring well into the summer. This species will hibernate either on the ground or in the water. When hibernating in the water, green frogs absorb dissolved oxygen through their skin; because the frog is mostly inactive, its oxygen needs are very low. Sometimes, green frogs are observed moving around in the water over winter during brief periods of activity...

You won’t hear frog and toad calls—that only happens at various times during the spring and summer, depending on the species.


Snakes are still around, but they are out less often as the days are cooler now.
It’s the same situation with turtles. Milder fall days are the best time to see turtles, especially painted turtles; they bask on logs or rocks near lake shores.


You can see frogs and toads through the end of September and into October on milder days. I’ve seen a few in the last week or so at various locations. Temperatures hit highs in the 60s to 70s, and these amphibians were doing their normal activities, mainly basking and foraging for food.
Being cold-blooded, reptiles and amphibians frequently bask in the daytime sun to regulate their body temperature.


When the temperatures start heading down toward freezing in October, frogs and toads start their hibernation activity. They will either bury themselves a few inches into soil or leaf litter, or in the water of a lake or pond, depending on the species.


These amphibians prepare themselves beforehand for winter hibernation by generating extra glucose from their livers. The extra glucose is a natural antifreeze and prevents the fluid around the cells from freezing.


In the spring, mild days will warm up the soil around the frog, and over the course of a few hours, this seemingly frozen frog-cube will thaw out, show signs of life, and eventually hop away to its springtime haunts.

Except when they breed in vernal ponds during early spring, wood frogs are typically found in forest habitats away from water. They hibernate by burying themselves in the ground under leaf litter. They will seemingly freeze, but in mid-March, they emerge from hibernation to be the first frog species seen and heard with the arrival of spring as they race to reproduce. The young have enough time to grow to adulthood before the vernal ponds they favor dry out in the summer heat.......
