Re: Ring species
The Greenish Warblers of Central Asia are a good example of a ring species - the two most northerly subspecies look much the same, but don't recognize each other's songs and don't interbreed. The other subspecies, circling Tibet, interbreed with immediate neighbors all the way around. I don't think there's much material on the Web on them, but I can get a citation to a paper in Nature if you're interested.

Re: Ring species
Oh, sorry, Hap! I lost this thread momentarily.
Irwin, et al., Nature vol 409, pp 333-337 (2001) is the article on Phylloscopus trochiloides, the greenish warblers that have subspecies around in a ring. You might ask your counterpart why they only "degrade" at the north edge of their range, though. If he says "because they were living under Godless Russian Communism," give up on him.
