pink pigeon
The pink pigeon (''Nesoenas mayeri'') is a species of Columbidae (doves and pigeons) endemic to Mauritius, and is now very rare. It is the only Mascarene pigeon that has not gone extinct.〔Hume, J.P. (2011). Systematics, morphology, and ecology of pigeons and doves (Aves: Columbidae) of the Mascarene Islands, with three new species. ''Zootaxa'', 3124:1-62. (Preview ) ISBN 978-1-86977-825-5 (paperback) ISBN 978-1-86977-826-2 (online edition)〕 It was on the brink of extinction in 1991 when only 10 individuals remained, but its numbers have increased due to the efforts of the Durrell Wildlife Conservation Trust since 1977.〔http://www.durrell.org/Animals/Birds/Mauritius-pink-pigeon/〕 The book ''Golden Bats and Pink Pigeons'' by Gerald Durrell refers to the conservation efforts. The IUCN downlisted the species from ''critically endangered'' to ''endangered'' on the IUCN Red List in 2006.〔 Mauritius published a series of postage stamps depicting the endemic pink pigeon.
==Taxonomy and evolution==
Initially classified as a true pigeon, it was reclassified in a monotypic genus by Tommaso Salvadori. Recent DNA analyses suggest its nearest neighbour on the phylogenetic tree is the geographically close Madagascar turtle dove (''Streptopelia picturata''), it has thus been placed in the genus ''Streptopelia'', which mostly contains turtle doves. However, the two species form a distinct group that cannot unequivocally be assigned to either ''Streptopelia'' or ''Columba'', and indeed, placing the ''two'' species in ''Nesoenas'' may best reflect the fact that they seem to belong to a distinct evolutionary lineage (Johnson ''et al.'', 2001).
