The crowned pigeons (Goura) is a genus of birds in the family Columbidae. It contains four large species of pigeon that are endemic to the island of New Guinea. The species are alike and replace each other geographically. The genus was introduced by the English naturalist James Francis Stephens in 1819.

Systematics and evolution[edit]

The genus Goura was introduced by the English naturalist James Francis Stephens in 1819. The type species is the western crowned pigeon.[1][2] The word Goura comes from the New Guinea aboriginal name for crowned pigeons.[3]

The genus contains four species:[4]

Scheepmaker's crowned pigeon and Sclater's crowned pigeon were previously considered as conspecific with the English name "southern crowned-pigeon".[4]

A molecular phylogenetic study published in 2018 found that the four species in the genus formed two pairs: the western crowned pigeon was sister to Sclater's crowned pigeon while Scheepmaker's crowned pigeon was sister to the Victora crowned pigeon.[5]

Description[edit]

They are natives of New Guinea and a few surrounding islands. They forage on the forest floor eating fallen fruit, seeds and snails. The males and females are almost identical, but during courtship the male will coo and bow for the female. Both parents incubate one egg for 28 to 30 days and the chick takes another 30 days to fledge. The life span can be over 20 years.
