圣诞岛皇鸠

The Christmas Island imperial pigeon (Ducula whartoni) is a large frugivorous pigeon in the family Columbidae, endemic to Christmas Island, an Australian territory in the Indian Ocean. It is one of several vertebrate species unique to Christmas Island, reflecting the island's isolation and the evolutionary divergence of its fauna over millions of years. Like other members of the genus Ducula, the imperial pigeons, it is a substantial bird and an important seed disperser within the island's rainforest ecosystem. The species feeds primarily on forest fruits and plays a keystone ecological role in moving seeds of large-fruited trees across the island. Imperial pigeons in this group are often characterized by pale gray and iridescent plumage. The Christmas Island imperial pigeon inhabits the dense tropical rainforest that covers much of the island's interior plateau. Conservation threats include habitat loss from past phosphate mining operations and the ongoing impacts of invasive species, particularly the yellow crazy ant, which has dramatically altered forest ecology through the farming of scale insects, leading to canopy dieback over large areas. The species' restricted range and dependence on intact forest make it susceptible to further habitat deterioration. Active conservation management on Christmas Island includes invasive species control programs.
