Photo of the Week: Early Spring Frogs Thaw Out and Start Singing

 

This Chorus Frog in mid-cheep is thawed and singing, but spent the winter frozen.

Early spring frogs have resurrected and their music fills the air! When the first ice of last winter formed on these little amphibians, they reacted by producing a glucose anti-freeze. According to Bernd Heinrich’s book, Winter World, “In about fifteen hours, the frog is frozen solid except for the insides of its cells.  Its heart stops. No more blood flows. It no longer breathes. By most definitions, it is dead.” But as the weather warms, chorus frogs, wood frogs, and spring peepers thaw out and begin to serenade their mates in your local vernal pool or wetland. Spring Peepers (Pseudacris crucifer) are nocturnal, but you can hear Chorus Frogs (genus Pseudacris) and Wood Frogs (Rana sylvatica) singing all day. Enjoy nature’s spring miracle!
