WORLD MIGRATORY BIRD DAY is a conservation initiative that brings awareness to conserving migratory birds and their habitats throughout the Western Hemisphere of the world. When birds migrate between nesting and wintering sites, they don’t just stop anywhere; they rely on a handful of resource-rich and strategically located sites where they increase their body weight as they acquire the energy-rich fat stores needed to fly thousands of miles across continents and oceans. These places are known as stopover sites. Alma, Wisconsin is well known as a stopover site, where birds stop while traveling along The Mississippi Flyway.
