More nomenclatural 'chaos' to vex Panov... ;)

Doesn't support the split of Cettia (diphone) canturians Manchurian Bush Warbler (including ssp borealis), as recognised by, eg, Monroe & Sibley 1993, IOC, BLI, Kennerley & Pearson 2010, Brazil 2009.
[Curiously, Cornell (Clements) recognises C canturians (monotypic) as 'Manchurian' Bush-Warbler, but excludes the Manchurian ssp (borealis)!]

15. CETTIA MINUTA.
A female shot near Chemulpo on the 10th September, 1888.
I have seen this Bush-Warbler on the road to Yong-heung, also in the middle of September.
My specimen is very slightly suffused with rust-colour on the forehead, and resembles examples from Chcfoo and Formosa which have been recorded as Cettia cantans minuta (Seebohm, Cat. Birds Brit. Mus. v. p. 140).
Cettia minuta only differs in size from Cettia canturiens, exactly as Cettia cantillans differs from Cettia cantans. It has been suggested that the smaller examples are the females of the larger ones, but until a pair have been shot at the nest of each of these species this view must be regarded as somewhat doubtful. In both Cettia minuta and Cettia canturiens examples from South China, where the species are said to be resident, are much more rufous, especially on the forehead and upper tail-coverts, than examples* from North China, where they appear to be migratory. The types of both species are in the Swinhoe Collection, and unquestionably belong to the rufous race of each species, which are resident within the Oriental Region. I propose to distinguish the less rufous race of Cettia minuta, which is a migratory bird breeding in the Palearctic Region in Corea, Chefoo, &c, as Cettia minuta borealis; and the less rufous race of Cettia canturiens, which is also a migratory bird breeding in Russian Manchuria, and possibly in Central China, as Cettia canturiens septentrionalis.

Hartert in , Die Vögel der paläarktischen Fauna wrote “More recent authors write canturiens, which is grammatically correct.” I have seen Cettia canturians followed by exclamation marks and (sic) . It is a Swinhoe name from a 1860 Ibis.

Zoonomen uses borealis as a subspecies for C. diphone but why not use septentrionalis as well? Joking.

The samples of Cettia cetti are separated into two rather divergent, well-supported clades, representing western [cetti] and eastern [orientalis/albiventris] populations, respectively.
... This study suggests ... that Cettia cetti might be treated as two species. Detailed studies of these complexes, including vocalizations, are needed.

Maybe worth adding that C. c. cetti is pretty strictly non-migratory, while C. c. albiventris and at least some C. c. orientalis are migratory.

...and it's interesting that one of the Armenian samples of orientalis differs somewhat from the other two - multiple post-glacial colonisations or differing niches, perhaps related to altitude of breeding grounds?

Daniel Parker's analysis of Cetti's Warbler songs is very interesting, but is the variation he considers to be regional dialects at least partly just a reflection of a species with a naturally variable song? I can't say I would pay much notice to any of the cuts he links in his article if I heard them in Jersey!
 
Wei, Chentao; Price, Trevor; Liu, Jiayu; Alström, Per; Zhang, Yanyun. The evolutionary origin of variation in song length and frequency in Cettiidae warblers. Journal of Avian Biology, Accepted article 5 April 2017.

Abstract:

Aspects of bird song have been shown to correlate with morphological and ecological features, including beak and body size, and habitat. Here we study evolution of song length and song frequency among 30 species belonging to the Cettiidae. Frequency is negatively correlated with body size, and song length increases with latitude. Although migration distance correlates with latitude, the association of song length with latitude is only present within the non-migratory species, implying the association is not a consequence of migration. We place these correlations in a historical framework to show that the body size-frequency association arose early in the group, but the latitude-song length association is more evolutionarily labile. We suggest that latitudinal correlates of song length may reflect increased importance of sexual selection by female choice.

Horornis fortipes

Wei, C., Dong, L., Li, S-H., Alström, P., Liu, Y., Xia, C., Yao, C-T., Zhang, Y., From Himalayas to Continental Island: Integrative species delimitation in the Brownish-flanked Bush Warbler Horornis fortipes complex, Molecular Phylogenetics and Evolution (2018), doi: https://doi.org/10.1016/j.ympev.2018.10.009

Abstract:

As species serve as basic units of study in many fields of biology, assessments of species limits are fundamental for such studies. Here, we used a multilocus dataset and different coalescent-based methods to analyze species delimitation and phylogenetic relationships in the Brownish-flanked Bush Warbler Horornis fortipes complex, which is widespread in the Sino-Himalayan region. We also examined the vocal and morphometric divergence within this complex. Our genetic results suggested that Horornis fortipes is composed of at least three independently evolving lineages, which diverged 1.1 – 1.8 million years ago. However, these lineages have hardly diverged in song or morphometrics and only very slightly in plumage. Our result indicate that there are three incipient species in Horonis fortipes complex diverged in central Himalayas and Hengduan Mountains, but not between the continent and Taiwan island.
