My friends and I camped on Bull of the Woods Mountain trail (elevation 11,400') outside of Taos, New Mexico and climbed Wheeler Peak (elevation 13,161') the following day. Canada Jay's were everywhere but I also heard chicadees, a nuthatch, and heard/saw a non-distinctive gray bird with a light wing bar and white on the outside of the tails. The gray bird was everywhere above treeline around the peak and had a one note chip and a three note chip reminisceint of a "per-chicoree" of the American Goldfinch. At this elevation, can the chicadee, nuthatch, or gray bird be positively identified? Thanks.
