Oct. 5 — closely pressed for thin
(no.1) entire length; His head, neck
and body were all in a nearly
quite vertical line the neck rather
shortened, the crest slightly raised,
the wing slightly spread ready for the
first stroke. As he sat thus turning
his sight hole squarely towards me
I was reminded forcibly of the bird
which I mounted years ago. Indeed
I could not possibly have done better
with this living model before me.
I watched the bird drum twice and
easily followed the wing strokes
which had a sweep of about 12 inches
beginning about 6 inches behind the
back and ending about the same
distance in front of the breast.
There is positively no doubt whatever
that the primaries for their entire
length stretch only the empty air
It is possible that the basal portion
of the wing may come against the
body but I take nothing to indicate
this and am still inclined: 1/2
Oct. 6 Although the entire day was
rather calm and very warm our Partridge
did not drum once during the forenoon.
He began at 4.30 P.M. and kept it up
until long after sunset, I watched him for
about an hour, and saw him drum 5 times,
the light was fairly good as I had previously
cut away all the intervening brush thus
was nothing between my glass & the bird.
He stood and drummed on exactly the
same spot as yesterday but feinted a little
more towards me; this enabled me to see
between his right wing and the body.
Although my previous impression that the
primaries were quite clear of the body
and well in front of it was fully confirmed
it was for the first time looked at
If the carpal joint struck the
side of the breast The plumage of which
seemed to be undulated and more or less
disarranged at each forward blow of the wing.
Perhaps after all, the drumming produced
partly by the thumping of the wing joint
on the breast and partly by the impact
of the primaries on the air. The bird
regularly raised its ruffs even at the
end of each drumming period but at no
other time. The crest was constantly raised.

Oct. 5 — to think that the entire
(no.3) wing twinges clear of the body
after the bird finished drumming
he spread his tail nearly to its
full extent and circled once
or twice as already described, then
he assumed the brooping attitude.

Oct. 13 Our Partridge drummed
at intervals for more than two hours
this morning, squawking at about half
I watched him several times under the
for the best conditions that I have ever
enjoyed. The light was clear and strong
and coming from behind me straight
and coming directly on the bird. We faced about
directly on the bird. We faced about

on quarter of the circle away from me
and I followed the wing during its
entire stroke and at the lower half
rather looked between it & the body. Neither
over the secondaries, nor
the primaries.
