The species prefers to colonize coastal and mangrove forests as well as garden areas from the plain to altitudes of 1150 meters.

Way of life

The birds feed on fruits, primarily various figs ( Ficus ) as well as Uapaca , Abrus and mulberry species ( Morus ). They can usually be found in pairs, but occasionally in groups of up to 70 individuals. The breeding season falls from September to December. The nest is made from twigs and moss by both sexes and has a flat, loose structure. It is placed at a great height in the fork of a tree and equipped with up to three eggs. Details on the breeding behavior are not available.

Danger

Madagascar green pigeons are widespread in Madagascar and are common in certain areas. They are also well represented on Nosy Hara and other islands of the Nosy Hara archipelago in northern Madagascar. It is therefore classified by the World Conservation Organization IUCN as LC IUCN 3 1st svgleast concern = not endangered”. Since the meat of the birds is considered a delicacy, they are hunted by the local population, but so far this has only led to temporary declines in populations.
