It feeds on leaves, young shoots, buds, flowers, fruit, and seeds of primarily native and some exotic plants. Macaque monkeys and black rats are nest predators. On the ground, introduced mongooses and feral cats are predators. Breeding occurs chiefly from December to June with a peak in May, though activity may be postponed in bad weather or lengthened in the event of repeated nest failures. The variation in onset and length of the breeding season is also affected by food availability, with birds starting to breed the month after the start of the summer rains.
Clutch size is one or two.
The pink pigeon is found only on the island of Mauritius in the Indian Ocean. It is restricted to the native montane evergreen forest and scrub that occurs in the southwestern part of the island. Nests are built 13 to 59 feet up in trees. The wild population now numbers about 25 birds. In addition, there is a released population of 21 captive-bred birds.
