Abstract
SUMMARYThe bowing display and other postures commonly seen in sexual display, of Australian and some New Guinea pigeons are described. These behavioural data are examined to determine how they support phylogenetic groupings based on the birds' morphology.The inclusion of Leucotreron and Megaloprepia in Ptilinopus is supported. Among the bronzewing pigeons Phaps, Ocyphaps, Geophaps and Petrophassa are very similar behaviourally, as well as morphologically; Petrophassa is the most divergent. The display postures do not assist the classification of Lopholaimus, Chalcophaps or Leucosarcia but, rather, emphasize the separation of these from other groups of pigeon species. The bowing displays of Geopelia and Streptopelia do not support the suggestion that G. humeralis should be moved from the former genus to the latter.
