The Mississippi River, which forms Iowa's eastern border, is an important migration corridor, with birds migrating along its course and utilizing its wetlands and floodplains as stopover sites. Another important corridor is the Great Lakes and Upper Mississippi River Valley, which connects the Great Lakes to the Mississippi River channel and provides migratory birds with a large amount of wetlands and forests to rest and refuel. Major stopovers along these routes include Saylorville Reservoir near Des Moines, which attracts large numbers of waterfowl and shorebirds during migrations; Rathbun Lake in south-central Iowa, another important site for migrating birds; and the Neal Smith National Wildlife Refuge Neal Smith National Wildlife Refuge, which has restored grasslands and wetlands that provide important habitat for migratory songbirds and other birds.
Notable Migratory Species and Their Seasonal Patterns
Iowa is home to a variety of migratory species, and seasonal migration patterns reflect their north-south migratory journeys. Waterfowl, shorebirds, songbirds and raptors are the primary birds that migrate through Iowa in the spring and fall. Ducks and geese, including Canada geese, mallards, and snow geese, use Iowa's wetlands and reservoirs as resting places during their journey. Shorebirds, such as sandpipers and plovers, frequent Iowa's wetlands and marshes on their way to northern breeding grounds, especially in spring and fall. Migratory songbirds, such as warblers, orioles, and fieldfares, are most active in Iowa in the spring as they travel north to breed. Raptors, including bald eagles and red-tailed hawks, pass through Iowa along migratory routes, often using rivers and ridgelines for navigation.
Common Bird Species of Iowa
Songbirds
Warblers are small, active birds commonly found in forests, woodlands and scrublands. They are known for their agility and often fly around trees and bushes, displaying vibrant colors and producing complex songs. Common warblers include the vibrant yellow warbler and the striking American red-tailed robin, both of which are popular with birdwatchers for their distinctive appearance and melodious tunes.
Robins are common in gardens, lawns and open woodlands, where they are known for their ground-feeding behavior and mellifluous song. They are easily recognized by their distinctive orange chest and cheerful song. The American Robin is a widely distributed species, common throughout Iowa, and can often be seen hopping through lawns and gardens in search of earthworms and other ground-dwelling insects.
Commonly found in grasslands, prairies, and urban areas, sparrows tend to forage on the ground, often in flocks. Characterized by a generally brown or gray body color with subtle markings, sparrows may not be as striking as other birds, but their behavior and adaptability make them fascinating to observe. Notable species include the Chipping Sparrow, which has a rufous cap on its head, and the White-crowned Sparrow, which has a black-and-white striped head.
Raptors
Eagles are majestic birds of prey often found near large bodies of water and open fields, known for their powerful aura and soaring flight. They usually glide gracefully through the air or perch at the water's edge, watching for fish or other prey. With their large size and distinctive appearance, eagles are hard to miss. The most recognizable species in Iowa is the Bald Eagle, characterized by striking white head and tail feathers. These iconic birds are symbols of strength and freedom and are often associated with grandeur and majesty.
Owls are nocturnal birds that inhabit forests, woodlands, and urban areas and are known for their silent flight and effective hunting skills. They usually hunt at night, relying on their keen senses to locate prey. Their distinguishing features include large eyes and facial disks, which help transmit sound to the ears. Common owl species in Iowa include the Great Horned Owl, which is known for its "horned" earlobes, and the Red Owl, which is known for the dark stripes on its chest and its distinctive hooting sound. These owls often perch in trees and watch for prey in the dark.
Shorebirds
Sandpipers are a coastal bird species that typically inhabit shorelines and wetland edges, and can often be seen probing for food on the ground or in the water with their elongated bills. Their behavior includes wading and pecking, which is characteristic of these birds. Sandpipers are known for their long legs and slender bodies, which help them navigate through shallow water and soft mud. The common sandpipers in Iowa are the least sandpiper and the pectoral-finned sandpiper; the least sandpiper is known for its small size, and the pectoral-finned sandpiper has a distinctive stripe on its chest and a more robust body. These birds are a familiar sight in wetland habitats during the migration season.
Plovers are shorebirds, commonly found along shorelines and sandbars, where they forage on the ground with a characteristic run-and-stop maneuver. They often fly quickly over sandy or muddy areas to peck at food on the ground. Plovers are known for their compact bodies and short bills, making them easily distinguishable from other shorebirds. A common plover in Iowa is the Killdeer, which has a striking double black band on its breast and a loud, piercing call. Plovers are often found in coastal habitats and exhibit unique foraging and movement patterns.
Rare and Endangered Birds in Iowa
Least Tern
The least tern is the smallest of the terns, characterized by a grayish-white body, black cap, and yellow bill. The bird typically nests on sandy or gravelly shores and lays its eggs in shallow scrapes in the ground. In Iowa, the least tern is considered endangered due to habitat loss and human disturbance (e.g., recreational activities and shoreline development). Conservation efforts are focused on protecting their nesting sites and minimizing human impacts to support the recovery of their populations.
