What Time is it in Nature?
Early summer is a time of tremendous activity here at Prairie Ridge.
The warm summer evenings have brought a chorus of sounds. Among
the many insects, birds, and frogs that call during the night, one
is distinctly loud. The Cope's Gray Treefrog Hyla chrysoscelis,
one of two species of gray treefrog found in our region, is
actively seeking mates. The male treefrog's raucous chirping can
be heard near Prairie Ridge's ponds as they attempt to serenade
nearby females. If successful, the pair will mate, resulting in
a mass of jelly-like eggs. These eggs are laid in the water and
will hatch into tadpoles that will mature into adult frogs and take
up residence in the pond's surrounding vegetation.
These small treefrogs are normally nocturnal, only becoming active
at night, but individuals can sometimes be heard calling during
the early mornings and on overcast afternoons. The adults can be
very difficult to find due to their cryptic camouflage that allows
them to blend in with their surroundings; however, the tadpoles
can be seen in the ponds and vernal pools of Prairie Ridge.
To learn more about frogs and how you can participate in researching
them, sign up for Frogwatch.
