spring peeper
Marsh's twilight vocalist
A spring peeper is a small tree frog native to eastern North America, named for its high-pitched peeping call that signals the arrival of spring.
The chorus of males calling from wetlands and woodland pools is one of the earliest signs of warming weather: We knew winter was ending when we heard the spring peepers.
