R.E.Johnson 1969 Journal 149 Feb.7 Boulder, Boulder Co. to Evergreen, Jefferson Co., Colorado Moved out of Bock's house, bought a second large cooler to place my birds in, exchanged a few ideas with Kathy & left for Denver just before noon. In Denver I bought 52 pounds of dry ice, had the front wheel alignment checked & the tires (front) balanced, & visited the Denver Museum of Natural History. Dr. Bailey took me out directly to the study skin collections with any fanfare. They have a good sized collection of birds collected in Colorado (littoralis 1 tray, atrata 1/2 tray, tephrocotis 3 trays, & australis 3 trays), but so far as I could tell, few or no other birds. The trays are small but jammed with birds. There were about 175 birds on the 3 australis trays & even more tephrocotis. I made distribution cards for australis & then drove to south park, arriving at Jefferson at about 7:30 PM (long after dark). I drove south of Jefferson 1.3 miles & turned left on a dirt road to the barn where I'd collected about a dozen australis from roosts inside a barn. I collected about 30 birds from the roosts by aiming my shotgun with the aid of a flashlight. Most were tephrocotis, but there were a couple littoralis & one australis. australis had been much more plentiful before. The first bird was collected at 7:45 PM & had a TB of 31.8° rather cold for a bird! Torpor? Several minutes later 2 more birds were shot & had TB's of 36.6° & 36.8°. Following the first shot there had been considerable fluttering in the rafters and I believe a few birds
