140 Journal R.E. Johnson 1967 August 27 Helena to Big Baldy Mtn, Little Belt Mtns, Judith Basin Co., Montana. occurs in the grasslands surrounding the mtn (see Hoffmann p.17) I also noticed them in the Flint Creek Range ( & collected one ) on Aug. 20, suggesting that they may commonly move up slope in the fall. One family of Phoebes was seen. A flock of Pine Siskins ( 7 birds) flew overhead at 3:15 pm. A family(5) of Robins was seen along the lip of the northern cirque. [illegible] appears An Audubon Warbler was also seen in the same location. These had previously be noted by me at high elevations on Elk Horn & Crow Mtns & in the Big Belt Mtns this fall. It appears that Sprague's Pipits, Say's Phoebes, Pine Siskins, Robins, and Audubon Warblers may all move to higher elevations after the breeding season. A Cooper's Hawk was seen flying 1st alpine record over the cirque & then perching on a cliff top. A number of Clark's Nutcrackers followed it, harassing it & also a few Rosy Finches joined the chase. One Rosy Finch (an Immature well advanced toward adult plumage) was collected along the lip of the south cirque and 6 (2 adults) were collected along the tops of the SW cliffs of the north cirque. The finches were abundant in the north cirque but were hard to reach (cliffs). Only the one bird was seen along the south cirque. Neither cirque was descended except to retrieve falled birds. Rosy Finches occasionally above the cirque fed on the turf with the pipits & also fled for cover from strong winds with them. One White-crowned Sparrow was cirque seen in a small bush along the rim. On returning down the mtn at dusk a Common Nighthawk was heard overhead (on south slope of Big Baldy well above timberline). This is only the second record for this species in the alpine here (see Johnson, 1962). Mammals
