November
15 [Day
52] (Cliff Hansen, assisted by Kevin Barker and Chris Hunt) The
temperature was -6C at 0815, rose to a high of 2C at 1400, and was
-1C at the end of the day. It was initially calm with NE winds 5-15
km/h developing after 1000, that gusted to 25 km/h around 1100 and
became light after 1600. Ridge winds appeared to be mainly light, and
it was essentially cloudless all day although up to 30% of the sky
was covered by degrading aircraft condensation trails for much of the
day. The final day of the fall 2012 count produced 6 migrant raptors
between 0959 and 1542, the flight comprising 4 Bald Eagles
(2a,1sa,1j) and 2 Golden Eagles of indeterminate age. All birds were
flapping continuously and appeared to have trouble maintaining
altitude. This is the sixth consecutive day that have produced two
migrant Golden Eagles, and the six days following the two days of
poor weather on November 8 and 9 yielded only 24 migrant raptors,
including the 12 Golden Eagles. By contrast, the 7 days leading up to
the poor weather event produced 370 migrants of which 305 were Golden
Eagles. This strongly suggests that birds were moving ahead of the
cold front that produced the two-day shut-down. Other birds seen
included a female Green-winged Teal on the river, 1 juvenile Northern
Shrike, 1 Golden-crowned Kinglet, 1 Pine Grosbeak and 1 Common
Redpoll.

further adventures of “Elaine” Elaine
spent several days, presumably hunting, about 10 km east of the
central part of Canyon Ferry Lake, but by November 15 she had moved
again to the NW and is presently east of the northern end of the
lake, close to where she was on November 4.
