Meet The Pink-Necked Green Pigeon – The Most Beautiful Pigeon In The World (15 Pics & Video)
Pigeons in the genus Treron are unusual in the family for not having cooing calls, instead making whistling and quacking noises, but some cooing notes have been recorded for the pink-necked green pigeon, as the male makes a tri-syballic whistling call ending in a coo. It is also reported to make a rasping krrak krrak... call, but the species is generally held to not be particularly vocal, usually only calling in communal roosts and when it finds food.
