Water Bird Species Found in Illinois 

American White Pelican

FeatureMeasurement
Scientific NamePelecanus erythrorhynchos
Length50–70 in
Wingspan95–120 in
Weight3.5 and 13.6 kg

The American White Pelican (Pelecanus erythrorhynchos) is one of North America’s largest birds, distinguished by its brilliant white plumage, elongated orange bill, and massive wingspan, which can extend up to 3 meters. This bird has a unique appearance with its distinctive pouch used for feeding and a “horn” on the upper part of the bill during the breeding season. Though a large bird, it is very graceful in flight, often seen soaring in flocks in a V formation.

American White Pelicans inhabit lakes, marshes, and salt bays, and despite their size, they are excellent swimmers. They feed primarily on fish, using a cooperative hunting strategy where they encircle schools of fish in shallow water and then scoop them up in their bill pouches. Unlike their brown pelican relatives, they do not dive for their food. During the breeding season, these pelicans will nest in colonies on islands in freshwater lakes.

Double-crested cormorant

FeatureMeasurement
Scientific NameNannopterum auritum
Length28–35 in
Wingspan45–48 in
Weight1.2–2.5 kg

The Double-Crested Cormorant (Phalacrocorax auritus) is a large waterbird known for its long neck, hooked bill, and almost entirely black body. The species gets its name from the two small patches of tufted feathers or “crests” found on the heads of breeding adults, one on each side. These birds are strong swimmers that propel themselves underwater with their webbed feet, their bodies submerged and necks above the water surface, giving them a characteristic snake-like appearance when swimming.

Double-Crested Cormorants are widely distributed across North America and can be found in a variety of aquatic environments including freshwater lakes, coastal areas, and rivers. Their diet primarily consists of fish, which they catch by diving from the water’s surface. Often seen perched with wings outstretched to dry after fishing, these cormorants nest in trees, on the ground, or on cliff edges, usually in colonies. While they have rebounded from decreases in the mid-20th century due to DDT-related reproductive failures, they face ongoing threats from habitat loss, entanglement in fishing gear, and conflicts with fisheries over their consumption of fish. Protection and careful management of their habitats are key to their ongoing conservation.

Great Blue Heron

Its distinctive flight pattern, forming a tight “S” shape with its neck, sets it apart from similar large birds, like cranes.

Inhabiting various wetland habitats, including marshes, lakes, rivers, and coastal regions throughout much of North and Central America, the Great Blue Heron is a wading bird. Often seen poised statue-like at the water’s edge, these birds are expert hunters, spearing fish and capturing small animals with their sharp bills.

The Osprey, a fascinating bird of prey, is universally known for its exceptional hunting prowess and striking physical characteristics. Osprey are dark brown hawks on the upperparts, contrasting beautifully with the predominantly white underparts, and a distinctive dark band that stretches across the eyes towards the sides of its head.

Equipped with specialized talons and a reversible outer toe, the Osprey’s hunting strategy involves a spectacular plunge-dive into bodies of water, often emerging with a fish securely gripped in its claws.

Found on every continent except Antarctica, the Osprey is a cosmopolitan species favoring habitats near water bodies such as lakes, rivers, and coastal areas, reflecting its piscivorous diet. This bird has a diet almost exclusively of fish, making it a unique member of the raptor family and often referred to as the sea hawk or fish hawk. They locate their prey from the air, often hovering before plunging feet-first to capture a fish. When it comes to breeding, Ospreys are monogamous, often mating for life.

They construct large, bulky nests made of sticks, lined with softer materials, and prefer elevated or isolated areas such as treetops or artificial structures like utility poles. Both parents share the responsibility of incubating the eggs and rearing the chicks.
