Does that mean you think the split wont be adopted?

Or that it will be adopted but the reasons why haven't yet been published?

The split will be adopted, but there's new evidence in the works that might cause the decision to be reversed.

Britain also has Barn Swallows, a bird which is endemic to everywhere except Antarctica and a few random islands. So it does have at least two endemic birds.

Spoil sport!

What is the deadline for the next version 14.2?

 

[Paul Clapham]

So I know "British Isles" is no longer a favored term in Ireland, but does that really leave one with no term with which to collectively refer to Britain, Ireland and the associated islands? If so, then that doesn't seem very useful, given these islands form a pretty clear geographical unit.

BirdGuides yesterday used the headline "British and Irish endemic" and I think that's the best that can be done.

What is the deadline for the next version 14.2?

No firm deadline yet. Version 14.2 will be delayed a bit because we lost approximately two months of collaborative time due to field work, vacations, etc. We are looking to complete it by the end of August, at the latest.

Ok. I wanted to send my Excel list of birds to Peter to integrate it into the file "comparison of IOC with other world lists"

Jun 20 Accept White-tailed Tityra as a valid species.

Jun 20 Post splits of Flores, Sumba and Timor Flowerpeckers from Blood-breasted Flowerpecker

As an American who has no dog grouse in this fight, I quite like the term 'Celtic Isles' that someone used.

That doesn't sound like time "lost", more like time well spent!

AS 14.2

Karimui Owlet-nightjar

Aegotheles terborghi

Barred Owlet-nightjar

Aegotheles bennettii

Karimui Owlet-nightjar Aegotheles terborghi was previously treated as a subspecies of A. bennettiito which it was provisionally assigned based on morphological similarities (Beehler & Pratt 2016). However, mtDNA analysis places it sister to A. affinis rather than within the A. bennettii clade (Dumbacher et al.. 2003). Further, A. terborghi is a montane from unlike other taxa within A. bennettii. Treat as a distinct species. Long known only from the type specimen but recently rediscovered (Lagerqvist et al. 2017).

 

[Swindon Addick]

The species updates page has Karimui Owlet-nightjar being added after Vogelkop Owlet-nightjar, matching the text description. It's not all that long ago that A. affinis was part of the A. bennettii clade.

White-tailed Tityra was seen as a form of Black-crowned tityra Tityra inquisitor until now; I'm not clear if it was part of any particular subspecies.

Don't think it was ever pinned down to that degree. From "Field evidence for the validity of White- tailed Tityra Tityra leucura Pelzeln, 1868" by Andrew Whittaker:

"the status ofT. leucura was consistently regarded as dubious; J. T. Zimmer (in Traylor 1979) concluded‘Its described characters suggest the possibility of abnormality in a subadult that is intermediate between T. i. albitorques and T. i. pelzelni, whose ranges involve other sections of the rioMadeira and its effluents’"

AS 14.2

Malaysian Cuckooshrike

Coracina larutensis

Large Cuckooshrike

Malaysian Cuckooshrike is split from Large Cuckooshrike on the basis of differences in morphology and vocalizations (WGAC 1088).

Jun 22 Post split of Yellow-throated Fiji Whistler from (White-throated) Fiji Whistler.


Jun 22 Post revisions to the Coracina macei/javanensis complex including the merger of Javan Cuckooshrike into Large Cuckooshrike and the recognition of Indian Cuckooshrike to a much restricted C. macei. Note required scientific name change for the revised Large Cuckooshrike.

So do any other subspecies remain with macei in the "new" Indian Cuckooshrike?" Unless my maths is wrong, 5 subspp being lumped with javanensis leaves one subsp to join macei? 🤔

It's also a little confusing (at least for me) having the reconfiguration down as a lump, because it is just as much a split, with the overall effect being no adjustment to the total number of extant species. The hidden split being Indian Cuckooshrike from Large Cuckooshrike. 🤯

javanensis ? or javensis ?

The other ssp. within Indian Cuckooshrike is the Sri Lankan taxon C. m. layardi.

This was a tricky one to announce since C. macei isn't exactly a split, it's a revised species concept for C. macei associated with an English name change. We documented these in the Taxonomic Updates and English Names sections.

Your point about treating the merger of Javan Cuckooshrike with the remaining taxa in Large Cuckooshrike is well taken. It's also tricky to express and, at conceptually, removes a species taxon and merges it with parts of another. Must ponder.

Thanks.
