HNC Hawkwatch 2019
Every year, from September through December, birds-of-prey enthusiasts gather at Hitchcock Nature Center to observe and count thousands of eagles, hawks, and other raptors as they migrate south. The broad expanse of the adjacent Missouri River Valley, combined with prevailing westerly winds that move through the Loess Hills, creates the perfect conditions for migrating raptors as they soar on thermals and topographic induced upward wind deflections in their journey south.
