Haha of course! Probably auto correct in action.Misprint for Haitian cave rail (Nesotrochis steganinos)?

First genetic data for the critically endangered Cuban endemic Zapata Rail Cyanolimnas cerverai, and the taxonomic implications
Journal of Ornithology (advance online publication)

The taxonomic affinity of the near-flightless Zapata Rail Cyanolimnas cerverai, a critically endangered and highly localized species endemic to Cuba, has long been debated. Morphological analyses have suggested that this species, which constitutes a monotypic genus, could be related either to the extinct Tahitian Cave Rails (Nesotrochis sp.) or to the South American rail tribe Pardirallini, i.e., the genera Neocrex, Mustelirallus, and Pardirallus. While pronounced phenotypic convergence—and divergence—among rails have repeatedly proven morphology-based phylogenies unreliable, thus far no attempt to sequence DNA from the enigmatic Cyanolimnas has succeeded. In this study, we extracted historic DNA from a museum specimen collected in 1927 and sequenced multiple short fragments that allowed us to assemble a partial sequence of the mitochondrial cytochrome oxidase I gene. Phylogenetic analyses confirm that Cyanolimnas belongs in tribe Pardirallini as sister to genus Neocrex, from which it diverged about 6 million years ago. Their divergence from Mustelirallus was estimated at about 9 million years ago. Based on morphology and our mitochondrial phylogeny, we conclude that it is unjustified to retain the monotypic genus Cyanolimnas and tentatively recommend that C. cerverai and the two Neocrex species are ascribed to genus Mustelirallus.
The authors know, they are working on a fixThere is an error in the abstract: Nesotrochis was a Caribbean (Haitian) genus not Tahitian.
In high mountain grassy meadows (at 1100-1250m asl) in Slovakia, I noted that Corncrake, treating me as a predator, would trot ahead of me on the path contour, occasionally calling, to decoy me away from the breeding territory. I imagine that duetting behaviour would not be an aid to survival for species that employ decoy tactics...!Daniel L Goldberg, Ben M Sadd, Angelo P Capparella, A rallid ballad: Communal signaling is correlated with year-round territoriality in the most duet-rich family of birds (Gruiformes: Rallidae), Ornithology, Volume 140, Issue 1, 12 January 2023,

I will not be able to judge the relevance of their result but Amaurornis isabellina is embedded into Zapornia

👌This position comes from the phylogeny of Garcia-R & Matzke 2021, which is simply adopted in the new paper (i.e., they did not do any phylogenetic analysis).
The position of isabellina in Garcia-R & Matzke 2021, in turn, rested exclusively of morphological data taken from Livezey 1998.
In Livezey's own analyses, these morphological data failed entirely to distinguish between the current restricted Amaurornis and Zapornia.
OTOH, Slika et al 2002 found Amaurornis isabellina to cluster with A. olivacea and A. phoenicura (with high support -- BS=99), outside of the clade which we now call Zapornia, based on mtDNA data (which they, however, did not make publicly available -- this was before the generalized use of GenBank -- and which therefore could not be included in Garcia-R & Matzke's "total-evidence" analysis).
Maximum travel distance recorded is 1070 km in South Africa; in the past it used to wander considerable distances in the Mediterranean, according to the Handbook of the Birds of the World.The type locality of Fulica cristata is Madagascar, but the species also occurs in Europe, East and South Africa. Is the species migratory or, on the contrary, is it sedentary? If it is sedentary, are we sure that the different populations belong to the same species?
It must go back a long way. It would be interesting to study the phylogeography of this species to determine the divergence between the different populations.but I bet things were different when the Sahara was greener.
BirdLife classes it as non-migratory, though the data tables indicate vagrancy to a good few countries. The small Oman breeding population might be a mix of Introduced and vagrant birds. I say 'might', because very recently Socotra experienced and influx of birds after adverse weather events over and beyond the Horn of Africa. These birds are now breeding in Socotra, but of course the tenancy of such a small population is vulnerable.The type locality of Fulica cristata is Madagascar, but the species also occurs in Europe, East and South Africa.

That still doesn't explain the gap of 4600km across the Sahara between the Moroccan and Ethiopian populations.
It was not the most exciting bird to look for at Lake Habbema in New Guinea but hey!The NW African range of the species was broader in the 19th C, though, when it bred in Algeria and Tunisia.
I guess surprises can happen, but the species has always been regarded as monotypic.
(I think there would be a much better chance to find mutiple species in F. atra.)
Surely not that long. ~6-9,000 yrs iirc.It must go back a long way. It would be interesting to study the phylogeography of this species to determine the divergence between the different populations.
Ok, I expected moreSurely not that long. ~6-9,000 yrs iirc.
