Narcondam hornbill  (Aceros narcondami)

Threats

Narcondam Island covers an area of only seven square kilometres (6), and thus the population of Narcondam hornbills is intrinsically small (2). Small populations restricted to tiny areas are always incredibly vulnerable to the impacts of any threats that may befall them. The most immediate threat the Narcondam hornbill faces is habitat deterioration (2). In 1969, a small police outpost was established on the island, leading to the loss of forest to create the post, a plantation of fruit trees, and vegetable plots (2) (7), and further trees are cut each year for firewood and intermittent maintenance purposes (7). Goats were also introduced to the island and their grazing has now eliminated most of the undergrowth and seedlings (2), significantly reducing natural forest regeneration (7). Feral cats, also introduced, are now abundant, but their impact on the Narcondam hornbill is not yet known (2), and around 25 to 40 Narcondam hornbills are thought to be hunted each year, although this is not believed to be a serious threat given the rate of breeding (2) (7). Nature brings its own problems for the Narcondam hornbill; the small, restricted population is susceptible to both disease and natural disasters, such as cyclones, which can fell large and important nesting trees (7).

Conservation

Narcondam Island has been declared a wildlife sanctuary and the police personnel on the island have been given strict instructions not to hunt the threatened hornbill (7). However, to ensure the long-term survival of the Narcondam hornbill, stricter conservation measures are required. As a priority, all introduced species, especially goats, should be removed from the island (2), and cooking fuel should be provided to the island's inhabitants to eliminate their need for fuelwood (7). To lessen the threat of natural disasters, it has been recommended that the possibility of establishing a second population on a nearby island should be investigated (7).
