Bonasa umbellus togata.
Lake Umbagog, Me.
Sept. & Oct. 1893. Bonasa togata
Oct. 13 of the breast while I
No 2) observed on the 6th & again
to-day is produced partly by the
wind from the wing feathers and
partly by the violent muscular action
of the pectoral muscles. Thus my old
theory as to the drumming of the Partridge
is again confirmed in every detail.
I had the curiosity, however, to ask each of
my three men to watch this bird through
the glass & give me their impressions.
All returned fully convinced that the
bird struck only the air; Jim had
never seen a partridge drum before,
Charlie Miller had never heard one do so.
The former thought that the wings
struck the log while that was perfectly
positioned that they struck the breast.
Of course neither had had any thing
like such a favorable opportunity before.
Miller's conversion especially pleased
and reassured me for he has been
grown up and taken his brother's drumming
is a remarkably accurate imitation.
