This week, Bob Danley of the Lee Metcalf Wildlife Refuge, near Stevensville, has seen some butterflies.

In our weekly Metcalf Wildlife Journal audio report, he describes what you can see and how these late season butterflies prepare for winter. They produce their own anti-freeze!

This is just one of the many topics we've covered in the reports, which are heard Thursday mornings at 8:05 a.m.
