Popular Birds with “U”
1. Upland Sandpiper
The Upland Sandpiper is a slender, long-legged shorebird that reaches about 12 inches in length. It has a small head, long neck, and yellowish legs, with mottled brown and buff plumage that helps it blend into grassy environments. Unlike many other sandpipers, it prefers open grasslands over wetlands.
- Region of Habitat: Found primarily in North America, especially the central U.S. grasslands and prairie regions; also migrates to South America during the winter.
- Scientific Name:Bartramia longicauda
- Feeding Habits: Eats insects, spiders, and other invertebrates by walking slowly through grass and picking food from the ground or low vegetation.
- What Sound They Make: Emits a long, bubbling whistle that rises and falls, used during flight displays and territorial calls.
Fun Facts:
Despite its name, the Upland Sandpiper rarely lives near water; it’s more at home in tallgrass prairies and pastures. It was once heavily hunted for food in the 19th century, which led to a significant population decline, though conservation efforts have helped it rebound in some areas.
2. Ural Owl
