Media notes
Compilation of 4 recordings of the same adult male bird. The bird was seen calling while foraging and seemed quite unbothered by the people in our group. Lots of background noise caused by people moving around and taking photographs. Song of Horned Larks and Tibetan Bunting sometimes disrupted the calls of the Sillem's Rosefinch, but the other species' vocalizations can be quite easily distinguished from the target species. Only 2 types of vocalization of the Sillem's Rosefinch were recorded in this compilation, the sharp downslurred whistles (presumably just a "normal" call) and a more "slurred" downslur call given in flight (only heard in flight and given the clear audible difference in quality, I'm tempted to assume it to be a flight call). *Only the last few vocalizations in the last recording are the "presumed flight calls"*. There was also one note in the second to last recording that was almost identical to the "presumed flight call" but I don't think it was given in flight. Wing noise was also recorded while the bird was in flight.
Observation details
2 seen by friends at around 8:20 am at c.5100m asl. 4 other seen foraging after 9:50 am at lower elevation (maybe c.5000m asl). Males and females not necessarily associating very closely. Photographed and audio recorded. Possibly the second ever audio recording of this species. At least one female was seen collecting and carrying nesting material (mostly thin strands of dry grasses. Collected at c.5000m asl, then flew higher up into the barren mountains, probably to 5100+m asl. Between 10:53~10:58am). Although some were seen foraging in close proximity to Tibetan Rosefinches, the Sillem's seem to prefer higher altitudes than Tibetan Rosefinches and are far less vocal than Tibetan Rosefinches. I suspect they likely roost and nest in higher areas and only comes down to c.5000m asl or less (plants and other living organisms more abundant here than higher uphill) to forage and collect nesting material. Other times likely spent in higher grounds (barren rocky habitat with little plant life). Observed foods items mostly consist of leaves, shoots, stems and buds of plants (not certain about this but they seem to like to pick food from between small rocks and not directly from larger exposed plant parts???). 1 additional female seen by another friend who stayed near the parking spot, according to the friend, this female was also collecting nesting material and carrying them uphill.
