About the Open Billed Stork

The Open-billed Stork (Anastomus oscitans) is a large wading bird found in parts of Asia and Africa.


Open-billed Storks inhabit a variety of wetland habitats, including marshes, swamps, floodplains, and rice fields. They are often found in areas with shallow water, muddy or sandy substrates, and abundant aquatic vegetation, which provide suitable feeding grounds for these storks. These birds are commonly seen in both natural and human-modified landscapes, including agricultural areas, urban parks, and reservoirs.


Open-billed Storks are large birds, measuring approximately 75 to 85 centimeters (30 to 33 inches) in length, with a wingspan of about 145 to 165 centimeters (57 to 65 inches). They have a long neck, a stout body, long legs, and a large, slightly decurved bill with a distinctive gap or "open" at the base. Their plumage is predominantly white, with black flight feathers on the wings and a black tail. Best Viewing The best places to view Open-billed Storks are in wetland habitats with suitable feeding areas, such as marshes, swamps, and rice fields. Look for them wading in shallow water or foraging for food along the water's edge. These storks are often seen in small to large flocks, especially during the breeding season when they gather in large colonies to nest and raise their young.
