Thank you Geoffrey, that is clear now.  A beautiful bird that I saw in the George Brown Botanic Gardens in Darwin on 3/7/13.

Lia   -   It depends on whether the Australian bird is regarded as a subspecies of the ‘imperial pigeon’ that is found more widely, in Indonesia for example.  That was the view taken as recently as  Christidis and Boles 2008, and gave you ‘D bicolor Pied Imperial-Pigeon’. The global lists (haven’t checked all of them) now regard the New Guinea/Australia species as separate,  D spilorrorhoa.

 

So the species on the Australian list is now (and I snip) –

 

 

There are also differences in the English spelling.  You will find the variations: ‘Imperial-Pigeon’, ‘Imperial-pigeon’, and ‘Imperial Pigeon’.

Is that 2 names in the same reference?  Looking at Avibase the taxonomy looks a mess but D, bicolor is the Pied Imperial Pigeon and D.  spilorrhoa  the Torresian Imperial Pigeon.  Checking the "related taxa" panel it looks like a mess with various 'authorities' engaged in trench warfare to preserve their own view of things.

For those who have expertise in taxonomy,  the above bird appears to have two scientific names:

 

  • Ducula spilorrhoa and
  • Ducula bicolor

 

Can you please explain this for me?

 

Many thanks

Lia
