The Northern Flicker is divided into two distinct forms: Yellow-shafted Flickers are more common in the eastern and far northern parts of their range, while Red-shafted Flickers are common in the West. Both forms can be easily seen at Wind Cave National Park. The easiest way to differentiate between forms is to look for the under-wing color when the bird flies. Both forms have a white rump which is conspicuous in flight. Flickers—unlike most other woodpecker species—can be seen on the ground looking for worms and insects in the soil. They can be easily seen near lawns in the visitor center area looking for worms and insects in the soil. They can also be seen and heard often in the park’s forested areas. Flickers can be seen at Wind Cave National Park throughout the year.
