Water Pipits and White-tailed Ptarmigan. All were seen feeding young on the meadows. The Ptarmigan hen was seen with 6 chicks at the head of a snowbank. Soft clucks seemed to signal "Freeze" to the young. Collected a Hermit Thrush. Mtn. Bluebirds & Clark's Nutcrackers were also seen. Hoary Marmots, Conyos, Golden-mantled Ground Squirrels, and a small gray shrew are also present. Noted that Pipits & Thrushes moved rapidly over meadow feeding whereas Rosy Finch is more sluggish & remains in a more limited area.
Some young Rosy Finches already are chirping with the adult quality (ex. # 210) whereas others still have the chicks begging voice (ex. # 205). Those Juveniles can fly quite well (can fly uphill), can perch in trees, & do peck at objects frequently, but are still fed by the adults and they (Juv.) seem to spend most of their time sitting waiting (& chirping) for the adults feeding trips. The adult feeds the young & then leads them off (in flight) to a new location (one under a large rock) to wait its next return. It appears that at least 2 families were using the meadow just east of the lookout. Horned Larks & Water Pipits were also using this area to fad young. The area has considerable snow and more Buttercups than anywhere else in the vicinity.
Rosy Finch adults seem to prefer dry looking (bare earth, steep slope) areas to feed. Close inspection reveals these areas to be soggy wet instead.
