Its distribution is fairly continuous in the East but patchy in the West. Isolated breeding populations occur in northern Utah and Nevada, central Washington, and eastern Arizona. Bobolinks do not breed in most of Utah. They occur in low abundance and in isolated patches primarily in the northern half of the state.  Bobolinks have one of the longest annual migrations of any North American songbird. These Neotropical migrants travel about 12,500 miles from their North American breeding grounds to their "wintering" grounds in southern South America. Bobolinks in the West nest and forage in wet meadow (grasses and sedges), wet grassland, and irrigated agricultural (primarily pasture and hay fields) areas. These habitats, particularly wet meadows, tend to be associated with riparian or wetland areas.
