hear young cheeping at #11.
At 10:30 I arrived at #7 with Dom Salemii from
the Willow Creek Ranch. I collected n, d, and dzn
in that order as they came to the nest. Then we
nailed cloth over the entrance and cut the tree
down and sawed out the section with the nest.
I chloroformened the young and opened the nest through
the top. There were 5 young in it, obviously not ready
to leave, but well feathered. Eggs had hatched in this
nest 24 days ago; perhaps the growth of the young
was retarded, or perhaps these hatched a few days
later. At any rate, on June 8 this nest had 6 eggs
and 2 newly hatched young; It is perhaps sig-
nificant that 5 young, the same number as the
usual clutch, is all that hatched or survived.
