Screhen Creek, California
Oct 13 and found 4 crossbills (10♂, 3♀) in
the net. 3 others were hanging
around, one of these was soon
captured, the next was shot by me
at close range after recordings of
vocalizations. The 3rd bird, a ♀,
was recorded, then I shot and
missed her at long range. Later,
a flock arrived, and of this
flock of about 12, 4 were captured
(3♂, 1♀). We went to have
lunch and got back, and a
large flock of about 18-20 came
from the N, and 11 of these
were captured (6♂, 5♀), the rest
flew off. All crossbills sounded
like Type 2 so far today. We had
a break at about 2:30, and got
back to the net around 3:15. Two
♂'s were in the net, of unknown
flock affiliation. Thus, 23 x-bills
total for the day. Interesting
that all the ♂'s were red,
and no birds had any traces of juvencal
plumage. The measurements correspond
to the vocalizations: Type 2. Little
