Taxonomy of Black-necked Stork
Here’s an excellent table detailing the taxonomy of the Black-necked Stork:
| Domain | Eukaryota |
| Kingdom | Animalia |
| Phylum | Chordata |
| Class | Aves |
| Clade | Aequornithes |
| Order | Ciconiiformes (Bonaparte, 1854) |
| Family | Ciconiidae |
| Genus | Ephippiorhynchus |
| Species | E. 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
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.
