 Wisconsin Nature Note  
To survive a Wisconsin winter, animals either migrate, adapt, or die – or MAD, and they have found ingenious ways to do so. A few migrate, others retreat to their dens, lower their body temperature and slow their heart rate and respiration. Things get exciting for birdwatchers in Wisconsin when food scarcities in Canada send birds like white-winged crossbills, purple finches and pine siskens—which don’t normally winter this far south—into Wisconsin. Listen in and learn what an “irruption” is and why they happen.
