11 June watch some crossbills after they
lost interest in the decays. A group
of four birds, three ♂♂ and a ♀,
were seen foraging on Englishman spruce.
The birds paid no attention to either the
old or new cones: foraging was strictly
on the new green shoots, at their
very tips. I do not know whether the
birds were eating the vegetation, but
I think the birds were searching for
arthropods.
Later, I walked a bit around the
"timber blowdown" area. I found a pair
(♂ + ♀) of crossbills, again they
began to forage on the spruce in the
way described above.
At a later time in the morning,
a group of crossbills came around
(3 ♂, 1 ♀), and I got some
recordings of one ♂ and shot him.
This was bird 422.
Crossbills were not encountered later
in the day. By before noon things
became very quiet, and while five
commoner cardinals continued to
be heard (pine siskins, Cassius finches)
crossbills certainly weren't around.
