The journey of three bird families – the Sandhill Crane, the Yellow Warbler and the Mallard Duck – is chronicled via footage of their fascinating behaviors. As the glaciers retreated at the end of the last ice age, they left connected rivers, lakes and wetlands across the heartland of North America. Today, these largely unknown water highways remain an oasis for sustaining wildlife. From the herds of bison that still roam the Great Plains to the vital honeybees that pollinate our crops and especially for the millions of magnificent birds that migrate along these “flyways.” (2023) — Sgt.
