Nocturnal Atlasing Week

Ready to hear some owls?

Atlasers throughout Wisconsin will be donning their headlamps and heading out for some night birding during Nocturnal Atlasing Week, April 21–29. This time window coincides with an early peak in owl calling, and is a good time to try to hear Barred Owls, Great Horned Owls, Eastern Screech-Owls, and Northern Saw-whet Owls, plus other crepuscular birds like American Woodcock.
