2018 New Caledonian independence referendum
New Caledonia was formally annexed by France in 1853, and Europeans and Polynesians, as well as other settlers, have since made the indigenous Kanaks a minority (27%, 11% and 39% respectively in the 2014 census). The territory was used as a penal colony from 1864 to 1897, and the Kanaks were "excluded from the French economy and from mining work, and ultimately confined to reservations". Between 1976 and 1988, conflicts between the French government and the independence movement saw periods of serious violence and disorder (culminating in the Ouvéa cave hostage taking in 1988), with the emerging Kanak independence movement gaining support from many Kanaks frustrated with their lower socio-economic status and lack of involvement in the economy, seen as problems caused by the French "exploitation". Though GDP per capita (nominal) is high at $38,921 and though New Caledonia is a major producer of nickel, there is significant inequality in income distribution, with many claiming that the mining revenue benefits people outside the territory and its (declining) mining communities.
Nicobar pigeon
From subfossil bones found on New Caledonia and Tonga, an extinct species of "Caloenas", the Kanaka pigeon ("C. canacorum") was described. It was about one-quarter larger than the Nicobar pigeon. Considering that it must have been a good source of food, it was most likely hunted to extinction by the first human settlers of its home islands. It probably was extinct by 500 BC. The Spotted green pigeon ("C. maculata") is a more recently extinct species from an unknown Pacific locality; it probably disappeared in the 19th century and most likely succumbed to introduced European rats. It is placed in "Caloenas" as the least awkward possibility; its true affinities are presently indeterminate and it is perhaps more likely to represent a distinct genus of the Indopacific radiation of Columbidae.
