Splits 2

Ah yes, rosellas, maybe we should split Adelaide and the FNQ birds as well? I opted for a compromise as it seems to me Yellow looks so different and has different habitat, but these things are not exactly set in stone, I fear it’s a case of large white-headed gull syndrome in Europe where there are a multitude of different ways to classify the species formerly known as Herring Gull. I tend to avoid going solely by DNA results, and like to look at morphology, habitat, vocalizations etc but it all comes down to a matter of opinion.

The Ringnecks are a similar category, there was very interesting paper a while back (which I don’t currently have to hand) which split out 3 quite distinct clades, roughly corresponding to Australian Ringneck, Mallee Ringneck and also Cloncurry Ringneck, and this made good sense to me though I have hedged on Cloncurry for the moment. Not sure where the Flinders Ra. birds fit, don’t they look like the western types? Be good to have a look at Double-eyed Fig-Parrots too.

Shrike-tits seem to me to be a clear cut split, with distinct morphology and occurring in areas with high endemism. Northern (and maybe also Western?) has very different calls, so rather than wait forever for DNA analysis results I went with what looks pretty clear already, indeed as the prescient Dick Schodde & ian Mason suggested in their landmark Directory of Australian Birds, where virtually all the proposed splits have come to pass or are pending.

    But then isn’t that an affectation of us humans to split according to visual differences (e.g. splitting Adelaide before recognising FNQ ”elegans” as species…)? Cas

    Phil, I’m not so sure about Shrike-tit vocalizations, a couple of years ago when a well-known NT birder and I were searching for them along the Central Arnhem Highway, we got no response from a recorded Northern Shrike-tit playback but as soon as I played the Eastern’s call on my phone 3 birds flew straight to us. (but that is my only experience of this subspecies calls 😉 )
