Type 4 bird (on tape). I took a shot
at the type 4 ♀, but only "stunned"
her, as she fell swinging upside down
in the tree, and as I reached for her
she flew strongly to nearby trees,
I thought I heard her mixing w/ the
type 2's but no visual sign of her.
Later, I caught a juvenile from
a flock of type 2's -- bird #52 (J66349).
I also set up a net on a ridge
above the camp, -- more exposed,
I heard birds through the
evening, but attracted none. I estimate
a total sightings as about 70 individual
Type 2's and 30 Type 4's -- most
were not identified to age or sex.
July 30 Today I collected a total of ten
crossbills: 6 Type 2's and 4 Type 4's.
I stopped netting between about
noon and 3 pm, to avoid heat
and I had already captured many,
I began to release some birds
arbitrarily.
Other flocks of crossbills were seen
today. Nothing but about a 65/35 ratio
of Type 2's to Type 4's -- and birds around
