Rosy Finches. A Clarke Nutcracker is raiding a ski Bowl Trash can.
9AM heard & saw Rosy Finch a rocky area protruding through snow on head of Squaw Creek. Followed it downhill to SW to rock outcrop overlooking Ski Bowl. Two other Rosy Finches also flew the same direction. Another seen where I saw the 1st one while I was elsewhere (naturally). Another flies east cross-slope in the direction I was originally headed (Mud creek). Several other non-directional chirps heard.
Clouds moved in about 9AM & now 10:30 AM are like a fog at this altitude (9300 ft.) making visibility 40ft.
AT 11:00 AM spotted 2 Rosy Finches on low cliff which faces west & is part of a rocky N-S ridge protruding from the snow. Collected both birds:
(1) The o appears to be littoralis (gray down sides of head below eye & under chin. More gray than Miller's two specimens), (2) ? appears to be dawsoni (no gray below eye). This means both races & [illegible] apparent hybrids occur here.
Clouds lifted, sun coming through (12:00 noon). Mtn. Bluebird flew up-slope past me. Several other Rosy Finches have flown over while I've been writing notes.
Usually they make the hoarse chirp note, but once this morning I heard the "oink" note and once I heard a bird who had [illegible] just landed apparently to feed give the chirp-oink(?) in couplets: "chirp-oink; chirp-oink; etc".

One of the two birds collected was inspecting the cliff face (entering all holes & cracks), perhaps for food
