Pheasant Pigeon

Otidiphaps nobilis

The Pheasant Pigeon looks like a small pheasant with its long, chicken legs but is actually a large pigeon -- like pigeons the adults feed crop milk to chicks and both parents incubate/raise young. It comes from New Guinea and adjacent islands where there are no pheasants/partridges so the Pheasant Pigeon, and the larger Crowned Pigeons, have evolved to fill the niche.
There are four sub-species. Shown is the nominate and more common: the Green-naped (although in most lights the nape looks more blue). Others are the White-, Grey- and Black-naped.
The scientific name "Otidiphaps" is made up of phaps: like the Bronzewinged ground pigeons and otidi from a perceived relationship to Bustards. Oditi would perhaps have been more appropriate.
