Pseudacris crucifer

The calls of spring peepers –known as pinkletinks on Martha’s Vineyard – are familiar to most residents of Massachusetts. Yet many people who know it by its high, clear, upward slurring whistle, have never seen this tiny ¾ to 1¼ inch treefrog. Listen for peepers calling from vernal pools, wet meadows and the margins of lakes and ponds throughout early and mid-spring.
