[Jim LeNomenclatoriste]

2024-B-5: Transfer Bluethroat Cyanecula svecica to the genus Luscinia

I am dismayed. Sometimes I wonder how avian taxonomists reason.

2025-A-6: Transfer Slaty-winged Foliage-gleaner Philydor fuscipenne to new genus Neophilydor

2025-A-7: Transfer Little Ringed Plover Charadrius dubius to Thinornis

On the other hand, that is an intelligent reflection. We can applaud them.

 

[Xenospiza]

The Dutch taxonomic committee puts Bluethroat in Luscinia.
I assume they discussed this with George Sangster!

My bad. George pleeeeeaazze !

My base is divergence time, branch length (in comparison with nearest clades)

I hope Boyd doesn't fall into this collective madness.

They may not have discussed it since 2012, though.
The 4-species Luscinia is not really appealing to me either. (The group is essentially undiagnosable morphologically. I'll stick to Cyanosylvia.)

 

[Xenospiza]

Reply from George (in Dutch) here: Roodsterblauwborst - Dutch Birding
Basically: he didn't propose to split the genus.

What a disappointing decision x)

Proposal batch C and D are now available

2025 Proposals - American Ornithological Society

2025 proposals for check-list

americanornithology.org

A lot of this, as is often the case lately, are proposals that are essentially catching up with Avilist, SACC and other checklists, but "new" proposals of interest in the newest set include:

Lumping Black-crested and Tufted Titmouse
Splitting Eastern vs Western Warbling Vireo
Transferring Fan-tailed Warbler to genus Euthylpis
Splitting Red-crowned Ant-Tanager into multiple species
Lumping Icteriidae with Icteridae (recommended no vote)
Lumping Phaenicophilidae, Spindalidae, and Nesospingidae into a single family
Revision of Columbidae taxonomy

 

[Jim LeNomenclatoriste]

Revision of Columbidae taxonomy

One of the figures shows very old lineages, almost 50 mya. Wouldn't that be a bit of an overestimate?

 

[raymie]

Lumping Icteriidae with Icteridae (recommended no vote)

Why would this be a recommended no vote when cross-familial hybrids are known? Doesn't that seem like it should be a slam-dunk one family?

 

[Mysticete]

All of the figures are from already published studies, so you would have to look those papers up to see the reasoning. Ages don't really matter much since it's mostly about the sequencing of taxa as far as the proposal goes

 

[Mysticete]

Why would this be a recommended no vote when cross-familial hybrids are known? Doesn't that seem like it should be a slam-dunk one family?

They provide reasoning in the proposals, I am just providing the quick and dirty synopsis of things people here would probably find interesting.

 

[Xenospiza]

Why would this be a recommended no vote when cross-familial hybrids are known? Doesn't that seem like it should be a slam-dunk one family?

They should all be in Emberizidae anyway, haha! These American microfamilies are quite nonsensical.

 

[Snapdragyn]

Yes, I love the way they refer to a 12MY divergence as 'old'. Um, had a look at Columbidae lately folks? o_0

 

[Jim LeNomenclatoriste]

They should all be in Emberizidae anyway, haha! These American microfamilies are quite nonsensical.

Microfamilies ? Thraupidae ? 😂😂

 

[Mysticete]

I think tentatively in my classification I have a very broad Emberizidae and I treat Thraupidae, Parulidae, etc as subfamilies.

Unlike your extreme groupings, I would see the Crinigerinae, Euphoniinae and Carduelinae as families.
