Identifying this majestic bird requires attention to detail and knowledge of its distinctive features. Here are some key points to help you determine the Black-necked Stork:

Size and Shape

The Black-necked Stork is a large bird, standing between 3.5 to 4.5 feet tall, with a wingspan of up to 7.5 feet. 

Its body is robust, with long legs adapted for wading through shallow water. The neck is long and slender, leading to a large, thick bill.


As the name suggests, the distinguishing feature of the Black-necked Stork is its black neck and head. 

The rest of the body is predominantly white, with contrasting black flight feathers and tail. During the breeding season, adults develop a pinkish tinge on the lower neck and chest.


The bill of the Black-necked Stork is long, straight, and dagger-shaped. It is yellowish-orange, with a slight downward curve at the tip.

The head of the Black-necked Stork is large and angular, with a distinctive black cap extending down the back of the neck. 

The eyes are small in proportion to the head and are positioned towards the front, giving the bird excellent binocular vision for hunting.

Legs and Feet

The legs of the Black-necked Stork are long and slender, adapted for wading in shallow water. 

The feet are large and partially webbed, aiding stability while walking on mud or soft substrates. The color of the legs varies from dull pink to reddish-orange.


In flight, the Black-necked Stork displays striking black and white coloration, contrasting wingtips and tail. 

Its flight is slow and steady, with deep wingbeats. When flying, the neck is stretched straight, and the legs extend beyond the tail.


Black-necked Storks inhabit wetland habitats such as freshwater marshes, swamps, and billabongs. 

They can also be found in rivers, floodplains, and rice fields. These birds prefer areas with shallow water where they can wade and forage for food.


When foraging, Black-necked Storks are often seen standing motionless in the water, patiently waiting for prey to come within striking distance. 

They use their sharp bill to spear or grasp food items, swallowing them whole or tearing them into smaller pieces.

Identifying the Black-necked Stork requires careful observation of its size, coloration, bill shape, and habitat preferences. 

By paying attention to these critical characteristics, birdwatchers and enthusiasts can easily distinguish this magnificent species in the wild.

Taxonomy of Black-necked Stork

Taxonomy of Black-necked Stork

Here’s an excellent table detailing the taxonomy of the Black-necked Stork:

OrderCiconiiformes (Bonaparte, 1854)
SpeciesE. asiaticus

The Black-necked Stork, scientifically known as Ephippiorhynchus asiaticus, comprises two recognized subspecies: E. a. asiaticus, found in the Oriental region, and E. a. australis, inhabiting South New Guinea and Australia. 

Despite being subspecies of the same species, they exhibit some differences in distribution, habitat preferences, and possibly minor morphological variations.

Ephippiorhynchus asiaticus asiaticus (Oriental Region)

  • It is found in the Oriental region, including India, Bangladesh, Myanmar, Thailand, Cambodia, and Vietnam.
  • Inhabits various wetland habitats such as freshwater marshes, swamps, rivers, and rice fields.
  • This subspecies may exhibit adaptations specific to the conditions of the Oriental region, such as different prey preferences or nesting behaviors.

Ephippiorhynchus asiaticus australis (South New Guinea and Australia)

  • Indigenous to South New Guinea and Australia, including regions like Queensland, the Northern Territory, and northern Western Australia.
  • It prefers similar wetland habitats as its Oriental counterpart but may show preferences for specific types of water bodies or vegetation.
  • It might display subtle morphological differences or behavioral adaptations suited to the environmental conditions of its range.

Despite these differences, both subspecies of the Black-necked Stork share common characteristics, such as their distinctive black and white plumage, tall stature, specialized feeding habits, and significant ecological roles in their respective habitats.

Reproduction of Black-necked Stork

Reproduction of Black-necked Stork

The reproduction process of the Black-necked Stork typically begins with courtship displays, which involve elaborate rituals such as bill-clapping, posturing, and vocalizations. 

Once a pair forms a bond, they construct a large nest of sticks, reeds, and other vegetation, often situated in tall trees or on elevated platforms near water bodies. 

The female usually lays a clutch of 2-5 eggs, which both parents take turns incubating for about 30-40 days. 

After hatching, the chicks are precocial and are cared for by both parents, who feed them regurgitated food. The chicks fledge after around 70-90 days but may remain dependent on their parents for several more weeks. 

Black-necked Storks typically breed once a year, with breeding seasons varying depending on the geographical location.

Black-necked Stork Life History

Black-necked Stork Life History

The Black-necked Stork (Ephippiorhynchus asiaticus), also known as the Jabiru, is a striking wading bird renowned for its distinctive appearance and graceful presence. 

This species plays a vital role in the ecosystems it inhabits, particularly wetlands and water bodies across Asia and Australia. 

Understanding its history provides insight into its behavior, ecology, and conservation needs.


Black-necked Storks are opportunistic feeders, primarily consuming fish, frogs, insects, crustaceans, and occasionally small mammals or reptiles. 

Their long, sharp bill allows them to capture prey in shallow water habitats efficiently. They employ a patient stalking technique, often standing motionless or moving slowly while foraging.


These storks inhabit various wetland habitats, including freshwater marshes, swamps, billabongs, rivers, and rice fields. 

They prefer shallow water, abundant vegetation, and ample prey availability. Human disturbances, habitat loss, and pollution threaten their preferred habitats.
