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
