Birders in the Great Plains know Hitchcock Nature Center for its excellent fall raptor flights. To the west, Iowa’s Loess Hills tower hundreds of feet above the nearly flat valley floor, reaching a height of 1,400 feet above sea level. A nearly unique land formation in North America, the hills are composed of soils deposited long ago on the eastern side of the Missouri River Valley by prevailing westerly winds. The topography and winds create conditions perfect for migrating raptors.
We hawk watchers count about 11,000 individuals of 18-20 species annually. North or northwest winds are generally best, but during the prime period, between September 20 and October 20, good flights can occur during a broad spectrum of conditions. Many other species, including Red-headed Woodpecker, Blue Jay, American White Pelican, and Snow Goose, can be seen migrating (at times in huge numbers) along with the raptors. While the fall flights are Hitchcock’s main attraction, the property and surrounding areas have much else to offer. Spring brings migrant songbirds, and in summer, approximately 100 species, including Lark Sparrow, Black-billed Cuckoo, and Blue Grosbeak, breed around the nature center. — Mark Orsag

It is much colder atop the tower than most people think it will be. Dress warm and in layers! Park trails can be surprisingly steep and demanding. If you hike the trails in spring or fall, bring bug spray.
