This week, Bob Danley talks about a little bird on the East Coast that actually changes its body in order to make a long migration flight. We don't see this bird on the Lee Metcalf National Wildlife Refuge, but there are plenty of other birds beginning their flights south.

This is another of our Metcalf Wildlife Journals that air weekly on KLYQ 1240 AM in Hamilton MT at 8:05 a.m. Thursdays.

If you have a nature topic you'd like to know more about, let us know.

Now, sit back, watch and listen.
