Tonight we heard the peepers** for the first time this year. Winter is coming to an end at last.
Spring peepers are small coppery brown frogs, Pseudacris crucifer, and their high-pitched peeps are actually the males calling to attract a mate. They hibernate in cold Maine winters, and in mid-spring, awaken when warm rain falls, and the ice is out on a nearby pond where they will breed. Check out the link to Wikipedia to hear a recording.
**Thanks Lou for pointing that typo out!
