Sandhill Cranes in WildHave you walked outside recently and heard a loud rattling bugle coming from the sky, and thought to yourself “what in the world is making that noise?” More than likely, you were hearing the calls of sandhill cranes. Often times you can hear the calls of sandhill cranes long before you see them, and sometimes you may never even see them. Sandhill cranes can fly at altitudes exceeding 1-mile high and their calls can be heard from more than 2 miles away.

Sandhill crane sightings are a common occurrence in Indiana from October through early-December and from February through March as the cranes migrate between their breeding grounds in Michigan, Minnesota, Ontario, and Wisconsin and their wintering grounds in Florida, Georgia, and Tennessee.

When and where to view sandhill cranes in Indiana

While sandhill cranes can be viewed throughout the state, Jasper-Pulaski Fish and Wildlife Area in Medaryville, IN is one of the top spots in the eastern U.S. to view sandhill cranes. Jasper-Pulaski lies in the heart of the sandhill’s migratory path, and the birds congregate here in the thousands to tens-of-thousand during the fall and spring migration. Jasper-Pulaski serves as an important staging area for eastern sandhill cranes during migration, and the cranes stop here to rest and replenish their fat reserves to complete the migration.

Fall is the best time of year to view sandhill cranes at Jasper-Pulaski, and more specifically crane numbers are the greatest from mid-November to early-December. The Indiana DNR has a website that provides information about the sandhill crane migration at Jasper-Pulaski. Managers at Jasper-Pulaski even track the number of cranes using the area weekly, throughout the fall migration, and post an estimated count to the website. On Nov. 7th, 4,630 sandhill cranes were counted at Jasper-Pulaski. You can view cranes from the observation deck located just to the west of the Jasper-Pulaski main office.

Other hot spots to view sandhill cranes during migration include Pigeon River Fish and Wildlife Area in northeast Indiana, Goose Pond Fish and Wildlife Area in southwest Indiana, and Muscatatuck National Wildlife Refuge in southeast Indiana.

GPS collars on sandhill cranes highlight importance of Jasper-Pulaski

Just how important is Jasper-Pulaski to sandhill cranes? Researchers with The U.S. Fish and Wildlife Service and the University of Minnesota attached Global Positioning System (GPS) collars to sandhill cranes to track their fall and spring migratory routes. A majority of the sandhill cranes, regardless of where spent the summer or winter, stopped at Jasper-Pulaski during the migration. Sandhill cranes spent 34% of the fall and spring migratory period at Jasper-Pulaski, which is almost twice as much time as any other single place on their migratory route. The map below shows the migratory paths taken by GPS-collared sandhill cranes during the fall (gold lines) and spring (blue lines).
