Wood Frogs return to the Vernal Pool at High Point Preserve
What brings the feeling that Spring has finally arrived? Geese formations flying North? Robins on the lawn?
Wondering if you will consider the Wood Frog?
For an amphibian that freezes over the winter, the Wood Frog is usually among the first amphibians to find the vernal pools and celebrate the arrival of Spring with their ‘cluck-like’ calls.
This video shows perspectives and audio from above the water surface and from below. The smaller male Wood Frogs compete to grasp onto the back (this is called “amplexus”) of the female filled with eggs. Sometimes multiple males are struggling to stay with the same female frog. Fertilization is external and the timing and proximity are important, since the egg must be fertilized before the gel-like mass surrounding the egg swells by absorbing water. After the eggs are laid, the adult Wood Frogs return to the forest, leaving the eggs, and later tadpoles, to survive on their own. Youtube link to the Wood Frog video: https://youtu.be/bxY7sGCfLP0
