Artikkelen i Birding Asia ligger ute i pdf-format på http://www.orientalbirdclub.org/publications/ba12pdfs/Timmins-LBWarbler.pdf

Det er forøvrig morsomt å merke seg at Svensson angir lengde og form på bakkloen (spissere og i snitt 1 mm lenger) og lengde og form på nebbet (busksanger opp t.o.m. 18.0 mm, orinus f.o.m. 18.0 mm, busksangerens nebb noe smalere) som de best skillende karakterene Ikke rart arten har blitt oversett!]]> http://feltornitologene.no/jforum/posts/preList/86/348.page http://feltornitologene.no/jforum/posts/preList/86/348.page GMT

För kännedom, Lars Svensson var precis på P4, Lotta Bromés program, där han berättade om upptäckten och även spelade upp sången.
Detta går nog att lyssna p i efterhand http://www.sr.se/sida/gruppsida.aspx?programid=2151&grupp=8985

Bestemmelsesartikkelen til Svensson som jeg refererte til i forrige innlegg, ligger for publisering som "early view" hos tidsskriftet "The Ibis", for de som har tilgang til det. Papirpubliseringen ko0mmer vel i neste nummer, tenker jeg:

The identification and distribution of the enigmatic Large-billed Reed Warbler Acrocephalus orinus
LARS SVENSSON 1*, ROBERT PRYS-JONES 2 , PAMELA C. RASMUSSEN 3 & URBAN OLSSON 4

Sammendraget ser slik ut:

ABSTRACT
We re-evaluate the characteristics of the little-known Large-billed Reed Warbler Acrocephalus orinus based on plumage and biometrical comparisons of 10 newly discovered specimens of A. orinus with a large sample of Blyth's Reed Warbler Acrocephalus dumetorum, the species most closely resembling A. orinus. Using specimens whose identity was verified by DNA analyses, we found that the most important criteria for identifying orinus are its long and comparatively broad bill, with typically uniformly dark upper mandible, and on average longer tarsi and claws with a thin and pointed hind claw. In contrast, previously suggested differences in wing formula, plumage colour and shape of flight-feathers are very minor, variable and seem of limited use for identification of orinus. Graphical analysis of hind claw length against bill to skull length should assist researchers in locating museum or live specimens of orinus that otherwise might be overlooked as dumetorum, and multivariate analysis unambiguously separates the two species based on our present dataset. A review of the scattered literature and specimen records suggests that the breeding distribution of orinus lies between southeastern Kazakhstan and northeastern Afghanistan, within the breeding range of dumetorum, but that orinus may well winter predominantly east of the main wintering range of dumetorum. Further evidence to support this assessment of the species' breeding range was obtained in June 2009, with the discovery of a population in the Pamir Mountains of Afghanistan.
