Hvidskægget Sanger splittes i tre arter?

Hi all

I was interested to see that, according to a new paper by Lars Svensson (Bull BoC 133: 240-248), the Subalpine Warbler Sylvia cantillans complex is now considered to involve three species – a split that has been on the cards since Hadoram Shirihai’s Sylvia Warblers (Helm) was published in 2001.

This taxonomic revision lists the three species as
Western Subalpine Warbler (S inornata, with subspecies inornata and iberiae),
Eastern Subalpine Warbler (S cantillans, with subspecies cantillans and albistriata), and
Moltoni’s Warbler (S subalpina, monotypic).

The name cantillans, previously associated with western birds, is linked with a type specimen from Italy, and this population is now assigned as Eastern.

A map in the paper showing the breeding ranges of all five taxa and the borders between the three species helps clarify the new arrangement geographically, and also illustrates the fact that Moltoni’s and cantillans Eastern breed sympatrically in northern mainland Italy.

Extralimital ‘Subalps’ away from the breeding areas are likely to attract even more attention in future, with the possibility of three rather than one or two species being involved. Moltoni’s is surely the rarest outside of its known range, with records from at least Belgium and the Netherlands and two or more good candidates in Britain; is anyone aware of other accepted extralimital records of this species in the Western Palearctic?

Hi Dominic

One from Helgoland 2-15.10-2009.

A good candidat from Denmark is a bird from Tipperne on 16th 2000. See the Picture in the Netfugl gallery.

Regards

Henrik

Spændende læsning! Hvor mange af de ganske mange danske fund er racebestemt?

Har SU taget stilling til racetilhørsforholdet i behnadlingen af hvidskægget sanger fund?

Skulle nogle have lyst til at læse lidt om det tyske fund fra Helgoland, så kan det læses via nedenstående link:
