April 3 The morning was sunny, cold, but not too

occasions in the morning -- all were of
Type 5 red crossbills. I had difficulty getting

I did manage to capture a lone female

waxwings also seen, also western bluebirds,
yellow-eyed juncos, pygmy nuthatches, Stellers
jays, ravens, pine siskins, evening
grosbeak (one fly-over), black-capped chickadee.

(bird red crossbill number 665) -- his crop was

the second pair come down around the
