Downloaded from Its population appears to be stable despite some degree of hunting and habitat degradation. 2014. 2012). Its small population and tiny range make it susceptible to natural disasters and disease, but the species population does not appear to have been affected by the 2004 tsunami.

The plan was finally cancelled by the Ministry of Environment and Forests in 2012. Trend justificationIts population appears to be stable despite some degree of hunting and habitat degradation. The iris of the male is orange red while the female has an olive brown with a pale yellow ring. The population has been estimated a number of times in the last few decades and appears to be roughly stable. Lynx Edicions BirdLife International, Barcelona, Spain and Cambridge, UK.

The male has a rufous head and neck, black body and upper parts glossed with green. Males have rufous head, neck and upper breast, blackish remainder of underparts and reddish base to bill. The reasons for the initial rejection of the plan still stand, and the construction phase is likely to cause disturbance to the species (K. Sivakumar in litt. The entire population (estimate of about 200 birds in 1905 and 1984) is restricted to the single island of Narcondam in the Andaman Island chain. Juveniles resemble males, but are duller-billed. Population justificationThe population is estimated to number 320-340 individuals, based on an area of habitat of 6 km2.

In 1992, the Salim Ali Centre for Ornithology and Natural History (SACON) began preliminary surveys of the avifauna on the Andaman Islands, with an emphasis on several target species, including Narcondam Hornbill. ; The hornbills are role ­model parents and also have unique nesting habits. A sizeable population of feral cats occurs which may pose a threat to the species. However most Narcondam Hornbill nests are found below 200m. Take your favorite fandoms with you and never miss a beat. The Narcondam hornbill (Rhyticeros narcondami) is a species of hornbill in the Bucerotidae family. The sexes differ in plumage. The likelihood of this increases as greater numbers of people access the island, likely to occur during the construction phase of the new radar station.

The Narcondam Hornbill is placed in the genus Rhyticeroswhich is found only in Asia. Volume 1: Non-passerines. Females are all black. The Narcondam hornbill is a small hornbill at 66 cm (26 in) long.

The species nests in holes on the trunk or broken branches of large trees and the female is sealed into a nest-cavity for the duration of egg-laying and chick-rearing (the breeding period spanning at least from February until April). The favored nesting trees are Sideroxylon and Sterculia species. The Narcondom hornbill has the smallest home range out of all the species of Asian hornbills.

While high densities for a hornbill, considering the tiny range they indicate that the number of mature individuals is consistently fewer than 250 (Kinnaird and O'Brien 2007).

About the Hornbill. Goats were introduced several times on the island in the past, and a visit in 1991 revealed that feral goats had proliferated around an old police outpost.

Approximately 20 hectares of forest have been lost since then to the creation of the post and plantations of coconut, areca, banana and vegetable plots (Raman et al. This is interpreted by Kinnaird and O'Brien (2007) to equate to fewer than 250 mature individuals, and so the population is placed in the band 50-249 mature individuals. The island is often hit by cyclonic storms in the Bay of Bengal. Nine species of fruits have been recorded in the diet (Yahya and Zarri 2002) as well as invertebrates and occasionally small reptiles (Vijayan 2009).

Strict instructions not to hunt the species have been issued to the personnel on the island. HBW and BirdLife International Illustrated Checklist of the Birds of the World.
