The proximity of Wind Cave National Park in South Dakota is within the geographic center of the continent. This blend of prairie and forest ecosystems provide homes to over 100 bird species found within the park, and you might find birds from both the east and west side of the country, like the red-headed woodpecker or the black-billed magpie. You might also see birds in this national park with combined eastern and western markings, like the northern Flicker, which will usually have the black mustache stripe of a flickr from the eastern part of the country, and also the orange or red feathers of a flickr found in the western portion of the country.
