[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] "We first met with U, pylzowi on the sources of the river Tetung, during the autumn migration, early in October 1872; and in the spring of the following year we again fell in with these birds there, early in April; and, as before, they kept singly or in small companies in plains and valleys near rivers, usually about the low thick bushes of Potentilla tenuifola. "Then, again, during our stay of more than a month in the mountains south of the central course of the Tetung, we did not meet with these birds, nor in the preceding year, and found them breeding only towards the end of May, in the alpine regions of the mountain north of the Tetung. Here, as also in the former locality, the birds kept almost exclusively in the bushes of [the same species]." (Prjevalsky [= Przewalski], 1877, p. 311-312) Prjevalsky [= Przewalski], N.
