Wildlife spectacle: 30,000 cranes fill Minnesota skies

Every fall, thousands of sandhill cranes descend on Sherburne National Wildlife Refuge ? a breathtaking stopover on their migration south. Around 30,000 of these elegant birds fill the skies and wetlands, their echoing calls marking one of Minnesota?s most spectacular wildlife events. Naturalist and crane expert Dean Kleinhans explains the timing, the behavior, and the best spots to witness this fall phenomenon ? from sunrise lift-offs to sunset returns.
