1 mi. N Tennessee Pass elev. 10,400 ft.
Eagle Co., Colorado
1 June
I chose to camp on the S end of
a clearing (pine/spruce savanna habitat)
just above a stream. No crossbills were
heard that evening.
2 June At dawn a lone type 5 crossbill visited
the camp, but showed little interest
in the two type 2 decoys (#'s 387 & 390).
Later, another type 5 bird came on
the scene, and I got recordings including
loops -- then made a playback loop
on cassette using this material. When
a lone type 5 male came around
later, I used this loop and caught
the male.
Later, I prepared bird 390 as a
specimen.
By noon it was blowing and rainy
so I decided to dismantle the net
and move on. Just before I left
the area, a pair of type 5 birds
arrived on the scene. As I scrambled
to set up the net, they flew on.
This locality was of lodgepole pine/
spruce forest, with old dry cones on
many of the mature spruces and
a very good crop of lodgepole cones.
