| The legs of P00976 looked quite yellowish in the field. Its white head, small yellow eye, eye-shadow, streaked collar and longish primary projection bears a remarkable resemblance to many of the putative mongolicus on Kim Hyun-Tae's site, but his birds have thicker pinker legs. Also mongolicus should have finished its primary moult. It remains unassigned.
P00977 has orange-yellow legs and a bright bill, but otherwise it looked like a Vega to me. It is also a slightly darker shade, so it could well be a hybrid with taimyrensis.
