146 R.E.Johnson 1969 Journal Jan.30 Boulder, Jefferson, & Clear Creek Counties, Colorado (cont.) south via Colo. Hwy. 93 to Morrison & then SW on US 285 over the mountains to south park, a large open park extending southward for 50 miles or more. A light layer of snow covered the ground. Only the highway & cow trampled parts of pastures were bare of snow. Mtns rise on either side. We stopped at several ranches & obtained permission to examine their barnyard areas for rosy finches. Everyone was quite friendly & agreed to let us look & even shoot birds. (1) The 1st ranch was located 1.2 miles nc of Jefferson (ie. 1 mi. n. & 0.7 miles east of Jefferson) on the west side of the highway, at 9500 ft. about 60 Many birds were feeding in one corral area both on the ground & in the feeding troughs. The flock was made up as follows: tephrocotis 70%, littoralis 20%, atrata 0%, australis 10%. I collected 21 birds: 14 tephrocotis, 3 littoralis, 2 intermediates (campestris - type) & 2 australis. The next ranch was located 0.6 miles SW of Jefferson along US 285 on the west side of the road (0.4 mi. S. & 0.4 mi. W. of Jefferson). This was the G South Park Cattle Co. They preferred us not to shoot near the buildings & nearly all the birds were close by so we only collected one bird, a tephrocotis littoralis. There were at least 40 birds present, a few in each small hay pile. About 50% were littoralis & tephrocotis, (2)
