Flock of red-winged blackbirds


  • During this time of year, many fish are moving about in Wisconsin's waters. They are exciting to watch as they dance, wiggle, and sail through the shallow waters of our rivers and lakes to find their breeding places. Watch for the walleye and learn where to watch for smelt.
  • Tree sap begins to flow as the days get warmer. Learn more about the sugar maple and where maple syrup comes from.
  • The male red-wing blackbirds return to Wisconsin from their warm southern winter vacation in late February and early March. You'll see them returning in large mixed flocks, sweeping across the sky and landing in chattering groups in trees and wetlands.
  • The woodcock, or timberdoodle, breed in March and April throughout most of the eastern United States and Canada. Learn more about this small long-billed bird.
  • Tundra swans breed and nest in the tundra and in sheltered marshes on the Alaskan and Canadian coast near the Arctic Circle. They pass through Wisconsin on their way north in early March through late May.
  • Listen in wooded brushy areas for the "drumming" of the male ruffed grouse from now until late May.
  • Listen near wet areas for the high-pitched "peep" of the spring peeper frog, the hoarse quacking of the wood frog, or a long "crreek" sound, like a fingernail pulled across the teeth of a comb, made by the Western chorus frog.
  • Spring is a time when many baby animals are born and you might discover young animals in your yard or in the wild. They are often cute, helpless, and seem friendly. Learn what to do and what not to do when you find them.
  • When the leaf of the bloodroot, an early spring wildflower, first appears it is wrapped around the flower bud.
