The Birdlife map shows Western as basically stopping at the Mongolian border, although they almost certainly do breed in western Mongolia, as does Little Crake. Birdlife map Brown-cheeked as entering central Mongolia from the north and extending down to the Khangai mountains. My record was just south of this, so Brown-cheeked would, probably, have been more expected in that area.
That's got the makings of an enterprising PhD study...!
