From personal interest, I'm wondering whether anyone knows of genetic work on the three subspecies of Turdus torquatus, nominate, amicorum and alpestris.

They all appear to differ in their wintering and breeding ranges, and subtly appear to differ in plumage detail. Does anyone know of differences in DNA and vocalisations? My rather meagre researches so far have revealed that Stejneger certainly considered torquatus and alpestris separate species in the mid-19th century.

Cheers

BOLD has barcodes from Norway (2, should be nominate) and from the Caucasus area (1 from Karachaevo-Cherkesskaya Rep., with an explicit annotation saying it is a breeding amicorum; 3 from Krasnoyarskiy Kray, an early May female and 2 late June juvs, the latter at least being certainly amicorum too; and 1, taken from GenBank, from Iran, without ssp ID or collection date).

All the barcodes are perfectly identical, except for that of the Karachaevo-Cherkesskaya bird, that differs from all others by 2 substitutions (0.3%).
