It seems that the Pied Imperial Pigeon (Ducula bicolor) and Torresian
Imperial Pigeon (Ducula spilorrhoa) are separate species in the IOU list.
Torresian Imperial Pigeon is the species in Australia plus se PNG.
Pied Imperial Pigeon is the species from SE Asia , Philippines,
Indonesia and w Papua.
There is an historical record in Feb 1899 of a pigeon in Flying Fish
Cove at Christmas Island. Presumably this would be the Pied Imperial Pigeon.
Does anyone know what the difference is between the two species? I
had thought that the Kimberley form was the same as Indonesia, and
these were resident species rather than migratory as Torresian
Imperial Pigeon. The Kimberley birds have an orange vent. But the
IOU have the Kimberley form as a sub species of Torresian Imperial Pigeon.
