Buceros bicornis
The largest of the nine horn bill species found on the Indian subcontinent, the Great
Pied horn bill also has one of the widest ranges, living everywhere from sea level to heights of nearly 5,000 feet. Doing justice to its name, the Great Pied hornbill can have wingspans of nearly five feet, with tails that can measure three feet. It is an
incredibly beautiful bird as well, covered in black plumage, with a yellow bill that curves downward. Most distinctively, the horn bill's head is topped with an ivory formation, also known as a casque.
This particular species of horn bill is chiefly fruit-eaters. Great Indian Horn bills like to eat various types of berries. Horn bills swallow
most of their food whole instead of breaking it down first. After they consume the food, they'll regurgitate what they cannot digest such as bones, and pits.
The males and females are mated for life. The usual clutch size is about 2-4 white round eggs. Th incubation period is about 28 to 40 days. It
takes for another 4-8 week for the youngsters to mature. The mothers, during this maturation period, remain with their offspring. The males take care of the females when they are incubating, and the offspring when they are young. The males would eat the food,
regurgitate it and give it to the young horn bills.
The female Great Pied horn bill's inability to leave her young is a story unto itself. She seals herself inside the hollow of a tree using her
own feces (males help with the process from the outside), and stays there until her young are born.
Nearing Extinction?
Now these wonderful and beautiful horn bills
are becoming rare. They are near the verge of extinction. The main causes of their endangerment are people hunting them for their meat and destroying their natural habitat. Large-scale killing of Horn bills occur in Pakhui Wildlife sanctuary ( A.P) for their
out-sized beaks, which the Nyshi tribals wear on top of their headgear in line with an old tradition. Wearing the beak, the tribe believes, is a sign of valour and masculinity, and the fact that the Nyshi form 50% of Arunachal's population is a measure of
the threat to the species.
Wildlife Trust of India has made the saving of these endangered species a special project. As part of the project, a large hoarding carrying
a warning that Horn bills are protected by the Village Forest Development Council, which would impose a fine of Rs 5,000 on anyone found killing the birds, was erected at the Seijosa check-gate of the sanctuary. WTI's Rapid Action Programme quickly had a
consignment of fiberglass beaks fabricated in Delhi and sent to Seijosa to wean the tribals away from killing Horn bills.
To muster maximum support and participation in this conservation effort, a host of key officials and other individuals were roped in to participate
in the inaugural function at Seijosa-- the District Commissioners of East Kameng and Pashighat, Chairmen of the various VFDCs, the Honorary Wildlife Warden, State Forest Department officials, village elders, local villagers, State Wildlife Advisory Board
members, and representatives of the ANWF.
Van Rakshak Project.
WTI's campign against hunting horn bills continues in Arunachal Pradesh.
