Vireo olivaceus

C.J. Battey, John Klicka. Cryptic Speciation and Gene Flow in a Migratory Songbird Species Complex: Insights from the Red-Eyed Vireo (Vireo olivaceus). Molecular Phylogenetics and Evolution. In Press, Accepted Manuscript, Available online 12 May 2017.

Abstract:

Migratory species that alternate between sympatry and allopatry over the course of an annual cycle are promising subjects for studies seeking to understand the process of speciation in the absence of strict geographic isolation. Here we sought to identify cryptic species and assess rates of gene flow in a clade of neotropical migrant songbirds in which geography and taxonomy are currently out of sync: the Red-Eyed Vireo (V. olivaceus) Species Complex. Phylogenetic, clustering, and statistical species delimitation analyses found that V. olivaceus includes two non-sister lineages migrating in opposite directions across the equator. Analyses of gene flow identified low levels of introgression between two species pairs, but none between northern and southern olivaceus. We also identified substantial well-supported conflicts between nuclear and mitochondrial topologies. Although the geographic distribution of mito-nuclear discordance is suggestive of hybridization and mitochondrial capture, we found no evidence of introgression in the nuclear genome of populations with discordant mitochondrial gene trees. Our study finds that species boundaries match breeding range and migratory phenology rather than the existing taxonomy in this group, and demonstrates the utility of genomic data in inferring species boundaries in recently diverged clades.

Winter ranges of olivaceous complex?

IOC Updates Diary July 2

Accept split of Chivi Vireo

Are there any publications dealing with the winter range of V. olivaceous (in the new sense)? In particular, I'm trying to puzzle out whether it regularly reaches Bolivia, as well as what those few Chilean records of the complex are likely to refer to, and the Battey & Klicka paper sticks to breeding ranges.
 
They were pretty common in the lowland areas of Manu during the non-breeding season when I was working out there so I would assume that they would also make it into Northern Bolivia. Can't help with the Chilean records unfortunately

*They* meaning chivi or olivaceus? And based upon voice or plumage?

Herzog et al. 2016, Birds of Bolivia indicates *Boreal migrant (olivaceus), austral migrant (chivi), and resident breeder (chivi); complicated, poorly understood overlap of resident and migratory populations.*

The 1957 Chilean record was olivaceus (specimen) according to Couve et al. 2016 (Aves de Chile) while the 2009 sight record record is vague, but one would assume olivaceus as well.

Thanks; that corresponds with what I would've guessed, but good to have some confirmation.

Multiple species and deep genomic divergences despite little phenotypic differentiation in an ancient Neotropical songbird, Tunchiornis ochraceiceps (Sclater, 1860) (Aves: Vireonidae),
Molecular Phylogenetics and Evolution, Available online 18 May 2021, 107206


Abstract: Several bird taxa have been recently described or elevated to full species and almost twice as many bird species than are currently recognized may exist. Defining species is one of the most basic and important issues in biological science because unknown or poorly defined species hamper subsequent studies. Here, we evaluate the species limits and evolutionary history of Tunchiornis ochraceiceps — a widespread forest songbird that occurs in the lowlands of Central America, Chocó and Amazonia — using an integrative approach that includes plumage coloration, morphometrics, vocalization and genomic data. The species has a relatively old crown age (∼9 Ma) and comprises several lineages with little, if any, evidence of gene flow among them. We propose a taxonomic arrangement composed of four species, three with a plumage coloration diagnosis and one deeply divergent cryptic species. Most of the remaining lineages have variable but unfixed phenotypic characters despite their relatively old origin. This decoupling of genomic and phenotypic differentiation reveals a remarkable case of phenotypic conservatism, possibly due to strict habitat association. Lineages are geographically delimited by the main Amazonian rivers and the Andes, a pattern observed in studies of other understory upland forest Neotropical birds, although phylogenetic relationships and divergence times among populations are idiosyncratic.

Very interesting! On a side note, does anyone know why IOC doesn’t split Hylophilus? It’s been a while since the last study and ”everyone else” has.

No mystery. This merely was overlooked somehow. Will address the Vireonidae taxonomy in IOC 11.2. Thanks for pointing it out!!

I was unaware of the existence of this study. Now I know the position of Vireo hypochryseus. Thanks David

Thanks for your speedy feedback, that's great! You do a fantastic work by the way.
 
Now I know the position of Vireo hypochryseus.
I'm more confused now than I was before, actually... :unsure:

In Slager et al 2014 (free pdf here), the position of hypochryseus was not satisfactorily resolved using nd2; but this taxon was sister to "canopy" Hylophilus (= Pachysylvia) with strong support in all nDNA and mixed mt+nDNA analyses. In Arbeláez-Cortés et al 2014 (here, but not free), Hypophilus muscicapinus (= Pachysylvia) also appeared closer to Vireo hypochryseus than V. latimeri, V. atricapilla, V. plumbeus, and V. leucophrys, using nd2 as well; I'm not clear about the support given to basal nodes in this tree, but this was, at the very least, fully compatible with Slager's nDNA and mt+nDNA-based findings. IOW, nd2 alone, in some analyses at least, did not appear to place hypochryseus where all the other analyses place it, but it didn't seem to contradict this placement significantly either.
In Mejías et al 2020 (free pdf here), hypochryseus is sister to the "eye-lined" Vireo clade with weak support (PP = 0.82 in their second supplementary file), and is part of a clade that also includes the "eye-ringed" and "spectacled" Vireo clades but excludes Pachysylvia, this one very strongly supported (PP = 1!).
If correct, we now seem to have a strong conflict between two published analyses, which we didn't have before.

Anyone have any information on the genus Thaumasioptera "Schiff" Bonaparte, 1854?

No description, no included species. This name never went past the state of pure nomen nudum, so far as I know.

Why does he attribute it to Schiff?

Bonapartee attributed quite a few names to Schiff in the period 1850-54.
These are all regarded as manuscript names by Schiff that Bonaparte was publishing for the first time. (They may have been names that had been used in a Museum collection -- Bonaparte regarded this as establishing a new name just as efficiently as a publication.)
Bonaparte left a significant proportion of these names nude; some of the genus-group name in this situation -- but not all, and not Thaumasioptera -- were subsequently made available by Gray in 1855, who published them with a type designation. "Thaumasioptera, Schiff, 1854" in Gray 1855: here.
 
Moritz Schiff worked at two museums:
"he became an apprentice in the prestigious Schankenbergische Institute of Natural History and, in 1844, received his M.D. in Göttingen after studying physiology with the famous Johan Müller in Berlin. His love of the natural sciences took him to Paris where he studied under one of the founders of modern physiology, François Magendie (1783–1855), and with his pupils, François A. Longet (1811–1871) and Carlo Matteucci (1811–1868). Concomitantly, he worked at the Museum of Zoology in the famous Jardin des Plantes. In the summer of 1845, he returned to Frankfurt and, in 1846, obtained the position of the director of the ornithological part of the Institute where he had worked in his youth. Schiff classified the birds of South America and collaborated with Prince Charles Bonaparte,"

Can we rehabilitate a nomen nudum by assigning it a type species by present designation?

e.g. we will say :

Thaumasioptera "Schiff" Bonaparte, 1854, Comp.Rend.etc... machin bidule. Type species : Hylophylus thoracicus Temminck, 1822, here designated or by present designation.

Diagnosis: blah blah..
