Spring Peepers
Fri Jun 06, 2003
Listen in RealAudio 
There are trees budding and the flowers blooming, but for me, there is only one true sign that
Spring has finally arrived.
Hi, I'm Bryan Yeaton, and this is The Weather Notebook. Those are Spring Peepers. Or, to be
more scientific, Pseudacris crucifer. The peeper is actually a tiny brownish frog, usually
about an inch long, from the Hyla family. It has a distinctive "X" mark on it's back, but what
makes it distinctive is that it's hardly ever a perfect "X."
When you hear this frog chorus, you are actually hearing the males inflating their throat sacs
in an effort to attract females for mating. Peepers live throughout the Eastern United States,
occupying ponds, marshes, pine barrens, and vernal pools. On the Internet, you can find
reports from Maine to Arkansas, Ohio to Georgia. You can even hear them on Staten
Island.
Poet Robert Frost wrote about how they called from a tiny rivulet behind his farm, Hyla Brook,
where he says they:
Shouted in the mists a month ago
Like ghost of sleigh bells in a ghost of snow
We call them Spring Peepers, but they can peep from March all the way through August, and even
into November. In the winter, they tunnel into shallow soil, where they actually can freeze
their body fluids, but not their organs. They are able to thaw in the Spring, ready to attract
mates with their song.
So some night soon, hide the remote, turn off the radio (for a while at least), and wander out
into the Spring Chorale. You might even get lucky and hear a whip-poor-will.
The Weather Notebook is produced by the Mount Washington Observatory, with support from
Subaru, and The National Science Foundation. Thanks to Emberly Hudak for her frog expertise.
