Jun 09, 2005 — Yesterday, we profiled Nina Schoch, head of the Adirondack Cooperative Loon Program. Schoch has been studying loons for six years, measuring their exposure to acid rain and mercury and trying to get an accurate measure of the birds' population. This morning, Brian Mann talks with Schoch about a program developed two years ago that tracks loons using satellites and radio transmitters. The goal was to discover exactly where Adirondack loons spend their winters.
