Grey/Silver Wood-Pigeon (Columba argentina)
The large, worldwide family of pigeons feeds predominantly on fruits, seeds, and berries, and all have rather compact, plump bodies and short, stout bills. They nest on flimsy twig platform nests, laying white eggs. Calls are repetitive, melodious coos, and in flight pigeons make a characteristic flapping noise. Thirty species occur in the Greater Sundas, comprising three species groups.
- Fruit-doves and green-pigeons - (Terron, Ptilinopus) - smaller, arboreal birds with generally brightly coloured plumage without metallic colours.
- Imperial pigeons - (Ducula, Columba) - large, arboreal birds with metallic sheen in the plumage and generally with grey or whitish underparts.
- Ground doves - (Macropygia, Streptopelia, Geopelia, Chalcophaps and Caloen'as) - birds which regularly visit the ground and have either highly iridescent, greenish upperparts, or drab, reddish brown colours.
