R.E. Johnson 1969 Journal 150 Feb. 7 Boulder, Boulder Co. to Evergreen, Jefferson Co, Colorado (cont.) lefts the barn. Perhaps the first shot started all the birds toward arousal? A bird shot at 7:55 PM had a T<sub>B</sub> of 38.4° and one at 8:00 PM had 33.5°. All of these were tephrocotis. A littoralis shot at 8:02 PM had 36.0°, a tephrocotis at 8:05 PM had 37.2°, a littoralis at 8:10 PM had 40.2° & an australis at 8:35 PM had 37.4°. There were many shots not listed above that preceded the australis. The other shots were listed in sequence. Most of the birds remained in place even when an adjacent bird, sometimes only 2 ft away, was shot. South Park had less snow & more bare ground near the barn than on my previous visits. It does not appear that the afternoon snowstorm touched this area. It did snow in Denver & Morrison & along the lower part of the road approaching South Park. It was clear at South Park with many stars. I drove back to Evergreen & noted they were resurfacing the large ice rink on the lake. Feb. 8 Evergreen, Jefferson Co. to Granby, Grand Co., Colorado I ice skated on the lake from 7:30 ~ 8:30 AM. It was +4°F at 9:00 AM! Then I drove north through Bergen Park to US 40 & west through Idaho Springs & over Berthoud Pass, looking for rosy finches in route. None. I continued down into Winter Park & stopped in Fraser to look for finches & around the house, barns, etc. I drove 0.7 miles west of town on a dirt road & stopped
