Sandhill Crane Migration: Identifying Those High-Flying Flocks

Mystery Birds in the Sky: Sandhill Cranes on the Move

In early January, a large flock of birds—over 50—was observed flying in two synchronized, rotating circles, with a pair flying alongside as if guiding them. They resembled geese but produced a high-pitched, rolling call quite unlike the deep honk of geese. Ornithologist Georgann Schmalz identifies them as Sandhill Cranes.

Migration Patterns and Habitat

Sandhill Cranes migrate through Georgia for about a month each winter, spending the season in southern Georgia (such as the Okefenokee Swamp) and Florida. They return north in late February and March to breeding grounds in the northern Midwest, Canada, and Alaska. Their distinctive circling flight behavior is often seen during migration as they ride thermal updrafts, and their unique vocalizations carry for miles.

If you spot large, gray birds with long necks and legs flying in loose formations and hear a loud, rattling "kar-r-r-o-o" call, you're witnessing one of North America's most ancient and spectacular bird migrations.
