Indian Ocean parrots

Jackson, Jones, Agapow, Tatayah & Groombridge (in press). Micro-evolutionary diversification among Indian Ocean parrots: temporal and spatial changes in phylogenetic diversity as a consequence of extinction and invasion. Ibis. [abstract] [supp info]
The close phylogenetic relationship and low but detectable nucleotide divergence between the single specimen of the extinct P. eques and the extant P. echo (0.2%) suggest that these island populations had evolutionarily diverged, but the low level of divergence suggests it is likely the populations on Reunion and Mauritius were only divergent at a sub-specific level. Comparable levels of nucleotide divergence are seen between some of the species of Coracopsis black parrots of the Indian Ocean; within this genus values range from 0.28% between the sympatric C. n. libs and C. n. nigra found on Madagascar, and 1.79-4.29% between them and C. sibilans on Grand Comoros and C. barklyi on Seychelles, although recent accounts describe the Madagascan subspecies as a single species and the Grand Comoros and Seychelles forms as separate species (del Hoyo et al. 2014, Jackson et al. submitted).
...
Our phylogenetic analysis suggests invasive P. krameri found on Mauritius and Seychelles originate from southern Asia and comprise two subspecies, P. k. borealis (introduced on Seychelles) and P. k. manillensis (introduced on Mauritius).

I think this was reported earlier by Kundu et al. 2012, The evolution of the Indian Ocean parrots (Psittaciformes): extinction, adaptive radiation and eustacy. Molecular Phylogenetics and Evolution 62: 296–305.

Doesn't Mascarinus Lesson 1830 have priority over Coracopsis Wagler 1832?

Martinet’s engravings in Buffon (1770–83): variation in their hand-colouring and its implications for defining Echo Parakeet Psittacula eques (Boddaert, 1783)

Bulletin of the British Ornithologists’ Club, 140(3): 299-308

Summary. —As explained in the Code (ICZN 1999), an illustration cannot be considered a type, which remains the physical specimen depicted in the photograph or depiction. Complexity arises if the illustrated specimen was unique and is no longer extant, meaning that the illustration is the only available visual representation of the lost type. In such cases how should we treat the illustration? As part of a wider study of the taxonomy and history of the Echo Parakeet Psittacula eques, we attempt to answer two questions pertaining to the specific case of Boddaert’s (1783) naming of a new species, P. eques from Réunion, which is now extinct there, namely: (1) were the published hand-coloured engravings by François-Nicolas Martinet on which Boddaert based his name illuminated by one hand?, and (2) how reliably do they represent the type? We conclude that the published illustrations were hand-coloured by different persons, and they vary too much to use them to ascertain the true appearance of the lost type. We suggest that only original drawings or the coloured original artwork (preparatory drawings) for the engravings or lithographs can used to establish the appearance of a type, if the specimen itself is missing.

I asked this question on the id thread in reference to pics from Mauritius but without response. Maybe this is a more appropriate place...

Does any one know how distinct echo and ring-necked parakeet are: morphology shows minor differences AFAIK , but are there any differences in ecology, resource use etc, and do they hybridise? As mentioned elsewhere, one study suggests echo is embedded in the ring-necked clade.
 
Going back into this thread there is a link to supplementary information showing that Echo parakeet together with a couple of other taxa are embedded within krameri. That would, however, only be a problem in the phylogenetic species concept but not necessarily in the biological.

It might be worth while to read some of the papers if you have access.

Thanks Niels but that isn't really my question (and I've already read at least enough of the papers to know they don't answer it). I'm interested if BF members know how echo behaves in the wild. For example, whether it regularly hybridises with ring-necked, but also if it's distinct in other ways: resource use, habitat preferences or whatever.

Of course, if there has been more recent molecular work that would be interesting too...

If you've read my other contribs here you'll realise I'm not (especially) interested in the official classification since any such can only be subjective.
 
I was hoping that there would be "hidded" information about e.g., habitat in papers that from the title might not be expected to contain that. In the Birds of the World account, competition for nesting sites is mentioned as a threat regarding RRParakeet, but hybridization is not.

RNP is a generalist, Mauritius parakeet is a native forest specialist. They don’t hybridise apparently.
They are fairly different phenotypically e.g. size, structure, plumage (especially female) and voice

I had an idea that echo parakeet chicks could be put for raising in rose-ringed parakeet nests, to establish a population of echo parakeets living in urban and farmland habitat in Mauritius. Echo parakeets could probably live in that habitat, given they are genetically very closely related to rose-ringed, and urban habitats suit very many parrot species worldwide. Rose-ringeds would be trapped out to prevent hybridization.

It might work biologically, but perhaps not organizationally.

Thanks: I wonder if that specialisation is obligate or just habitual. E.g. many species of insect can be raised on plants they're never found on in the wild, and wood pigeons, gulls etc have learnt to utilise UK towns where once they wouldn't haven't been found. If obligate, wonder what the basis is [e.g. various South American parrots are tied to particular palm species]

Makes you wonder why they introduced them in the first place... I can understand it if you're dealing with something which is very different to what you see around you ("exotic") but when you've already got something which is pretty much the same already...
 
Warning! This thread is more than 4 years ago old.
It's likely that no further discussion is required, in which case we recommend starting a new thread. If however you feel your response is required you can still do so.
