[Approximate date and pinned location, deduced from the text, Przewalski’s account of the journey (in two volumes), the expedition's detailed itinerary, and Petermann’s 'route-map' of c. 1876] Przewalski notes that this is a taxon new to science. "We met with these birds only in the Kan-su mountains (but some might have been in Tibet, although we did not obtain any), where it is only to be found in the alpine regions, and very seldom, by chance, in the woods. It usually keeps in thickets of bushes and on the ground, and is tolerably cautious. The note resembles the whistling of our common Bullfinch. The flight is high and wavy. About the middle of July the males were still moulting ; and specimens killed late in August were also moulting fast. Towards the end of April [1873] we found these birds in the mountains south of the river Tetung. Here they were flying about, in small flocks, on the alpine meadows."
