[Oenanthe seebohmi Seebohm's Wheatear is treated as a distinct species by Dutch Birding and UK400 Club.]

Has anyone investigated whether there are any genetic differences in the Northern Wheatear population breeding in the Alps? The males are very easily distinguished from "normal" passage migrants by their nearly pure white undersides. Visitors to the Alps from other parts of Europe always comment on their appearance so the difference is quite distinctive.

Libanotica vs Oenanthe?

Alps breeders are included within nominate oenanthe, according to BWP (but no mention of local characteristics):
O. o. leucorhoa (Gmelin, 1789), north-east Canada, Greenland, and Iceland;

nominate oenanthe (Linnaeus, 1758), Europe, western and northern Siberia, and Alaska, east from Faeroes and Ireland, south to Pyrénées, Alps, Yugoslavia, central Rumania, southern Urals, and Yakutia;

libanotica (Hemprich and Ehrenberg, 1833), Spain south of Pyrénées, Balearic islands, eastern Rumania, Crimea, Greece, Turkey, Levant, Iran, and from Kazakhstan (USSR) and Afghanistan east to Altai, Transbaykalia, and Mongolia;

seebohmi (Dixon, 1882), north-west Africa.

Hi Richard,

I read this range for libanotica, but I've seen libanotica phenotypes in Northern Italy in Alps... maybe just a local variation of oenanthe...

Cheers

Perhaps a good illustration of the problems with clinal subspecies. The type localities of oenanthe and libanotica are Sweden and Lebanon respectively, but who can define the notional boundary with any confidence?

The paper finds that the fragmented Wheatear populations in the Netherlands (down 80% since 1977) show little dispersal from the fragmented sites, making recolonisation of the remaining suitable but unoccupied habitat is highly unlikely. Depressing.:-C
