Caprimulgiformes (4 Viewers)

[Mike Earp]

Laurent can you explain the index for Scortornis in Swainson July 1837.
Scortornis, Sw:., generic character, 331. Subgeneric character and species, 339.
I do not see anything about Scortornis on p. 331

Presumably 331 is simply a typo for 339.

 

[jurek]

I would think the latter, why you don't want to lump songbirds together, would be obvious: A family with 870 species is huge and unwieldy, as you would get with the 9-primaried oscines.

Folks, to propose that all species, genera or families should be of the same size or the same age implies that natural selection in different conditions would proceed at the same speed. It is unscientific.

Folks, to propose that all species, genera or families should be of the same size or the same age implies that natural selection in different conditions would proceed at the same speed. It is unscientific.

But there must be some consistency within families because the fact that genera diverge at approximately the same time indicates that there was an event that produced diversification at a regular rhythm. When I see that the genus Lamprotornis is older than related multigeneric clades, I tell myself that there is a serious problem of taxonomic balance (although I see the same case in other families like Furnariidae).

 

[jurek]

I am not sure I understood what exactly you mean. However, bird phylogeny showed no times when lineages diverged more and diverged less. Which broadly proves that the concept of discrete ranks across lineages like genus, family, order etc. is arbitrary.

When I see the phylogeny of Muscicapidae, I notice that the average divergence time is around 10 mya, which gives a certain balance, as if the lineages evolved at a more or less regular pace.

I agree.
On p. 339, SCORTORNIS Sw. (small caps) is a genus, which includes subgenera Scortornis Sw., Macrodypteryx Sw. and Proïthera Sw. (italics).
Swainson gives characters associated to both ranks.

Note that it can be a false positive - it is just one of 100+ cases.

How to say "trépigner d'impatience" in English?

"Chomping at the bit" is a bit to literal; how about "I'm in jolted anticipation!"

(It's much easier to translate it into Dutch, which uses the same expression – and describes how I feel about this one, haha!)

(Gray 1840 was before Gray 1855; only the first designation has standing. Gray misspelled the name 'Hydropsalia' in 1840; this does not affect the validity of the designation. Anyway, Gray designated the same type while spelling the name correctly in 1841 [A list of the genera of birds - Biodiversity Heritage Library ], hence, even if the misspelling had made the 1840 designation invalid, the 1855 designation would definitely still be lacking standing.)

Jiminy Cricket Laurent that’s a tremendous amount of work! I had never seen Rivista contemporanea before.
“the genus comprises three lineages probably best considered separate species, the nomenclature of which is remarkably complicated. This case is under study and will be resolved in the near future...”
In 1850 Bonaparte published as a new species Caprimulgus minutus, At the end of description he states “Vix hujus generis!” Hardly of this kind! On that page is (leucopygius Spix) in brackets.
t.1 (1850) - Conspectus generum avium - Biodiversity Heritage Library .
In 1854 Bonaparte creates a new genus Nyctiprogne but it is lacking the genus species.
ser.4:t.1 (1854) - Annales des sciences naturelles - Biodiversity Heritage Library .
Could N. minutus be reused for one of the three lineages? There must be a Natterer skin in Vienna?
I spoke too late: Recognize minuta Bonaparte as the second species in the genus Nyctiprogne .
Other options:

Nyctiprogne latifascia Friedmann 1945
Nyctiprogne leucopyga exigua Friedmann, 1945
Nyctiprogne leucopyga majuscula Pinto & Camargo, 1952
Nyctiprogne leucopyga pallida Phelps y Phelps 1952
Nyctiprogne vielliardi .

Proposal (1005) to SACC

Revise the classification of New World nightjar genera

 

[Jim LeNomenclatoriste]

King, B.F., Sangster, G., Trainor, C.R., Irestedt, M., Prawiradilaga, D.M. and Ericson, P.G.P. (2024), A new species of nightjar (Caprimulgus) from Timor and Wetar, Lesser Sunda Islands, Wallacea. Ibis. https://onlinelibrary.wiley.com/doi/full/10.1111/ibi.13340

Abstract
The nightjars of the Caprimulgus macrurus complex are distributed from Pakistan to Australia and comprise six morphologically similar but vocally distinct species. Fieldwork on Timor and Wetar, Lesser Sunda Islands, has resulted in the discovery of a seventh species in the complex, which we describe as a new species. This species has previously been confused with Caprimulgus macrurus, Caprimulgus celebensis and Caprimulgus manillensis but it differs from these and all other species in the complex by at least 13 vocal characters. Discriminant function analysis correctly classified all recordings in the complex to species. Caprimulgus ritae is known from five adult museum specimens, which are the smallest in the complex and which differ from other species in the complex in several morphological characters. A molecular phylogenetic analysis indicated that C. ritae is sister to C. meesi from Flores and Sumba, and that these species together are sister to C. macrurus. C. ritae is a tropical forest specialist occurring from sea level to at least 1500 m (probably mostly below 1000 m). Lowland and montane forests on Timor are threatened. Wetar is one of the least developed islands in Indonesia, and retains >95% natural vegetation, dominated by Eucalyptus woodlands, with tropical forests in river gorges and slopes in upland areas. Pressure for development is accelerating throughout the range of C. ritae, and a detailed assessment of its conservation status is urgently needed.

Caprimulgus ritae new species.

I was aware of this new species name since many month 😅
