Southern Boobook Ninox boobook and Morepork Ninox novaeseelandiae are separated at the species level (formerly known as Southern Boobook Ninox boobook). Southern Boobook is widespread in Australia, New Guinea, Timor, and Indonesia, while Morepork is restricted to Tasmania, New Zealand, and Norfolk Island (a Lord Howe Island subspecies is extinct). We expect more splits in Southern Boobook in the future, since the subspecies groups Southern Boobook (Alor) Ninox boobook plesseni, Southern Boobook (Rote) Ninox boobook rotiensis, and Southern Boobook (Timor) Ninox boobook fuscaeach probably deserve species status. Stay tuned!

The two can both occur in southern Victoria, Australia, where it seems that some Tasmanian Moreporks (sometimes separated as a species in their own right) seem to move to the mainland in winter. For this reason, we retain a slash option to promote conservative reporting.

Rufous Fieldwren Calamanthus campestris is split into a widespread Rufous Fieldwren Calamanthus campestris found across much of Australia and a range-restricted Western Fieldwren Calamanthus montanellus restricted to just the southwestern corner of Western Australia.

In perhaps the most surprising taxonomic revision for this update, subspecies melanorhyncha, previously classified as a subspecies of Little Shrikethrush Colluricincla megarhyncha (in the group Little Shrikethrush (Arafura) Colluricincla megarhyncha [megarhyncha Group]), in fact is a whistler (Pachycephala)So the genus was not even right! Correcting this taxonomic issue, we now recognize melanorhyncha as a species, Biak Whistler Pachycephala melanorhyncha.

Pacific Robin Petroica pusilla is fairly widespread in the south Pacific, but the population on Norfolk Island has always stood out as having a distinctive plumage. It is now split as Norfolk Robin Petroica multicolor and is no longer thought to be most closely related to Pacific Robin.

Two subtly different gulls, the Red-billed Gull Chroicocephalus scopulinus and Silver Gull Chroicocephalus novaehollandiae are lumped as a single species known as Silver GullChroicocephalus scopulinus. The two are retained as identifiable subspecies groups, but as is the case with many subspecies of gulls, the two are barely identifiable and only the extreme “larophiles” claim they can separate them reliably.

The Lord Howe White-eye Zosterops tephropleurus is now considered to be “just” a subspecies of Silvereye Zosterops lateralis, now Zosterops lateralis tephropleurus. It is not even considered distinctive enough to be retained as an identifiable subspecies group, so is addition to the loss of a Lord Howe Island endemic the main result is a tiny expansion in the range of Silvereye to include Lord Howe Island.
