looking out of an upper story window across the street and talking
to Rhody. When I spoke to her she said Rhody was part way down
the bank, with his tail flattened up against it, near the corner of
the fence, and that when I spoke he had turned his head in my
direction and moved up the bank toward me. Neither Rhody nor I
could see each other. Mrs. S. said: "He is coming to you." I said:
"It's too bad, I shall have to disappoint him as I have nothing for
him to eat". (I had gone there merely to locate the birds, not
expecting that R would come for food so early). In a few moments
he came trotting along the fence, crouched and flew over and
walked up to me waiting expectantly, to the great pleasure of my
neighbor. The best I could do under the circumstances was to
invite him to follow me up to the tool-house; accordingly he trot-
ted along at a respectful distance behind me and had his live
mouse. This disposed of, he climbed part way up a pine tree, found
a nice sunny place and proceeded to warm his back.
This seems to be a clear instance of Rhody's recognizing my
voice, locating me by it alone (though of course assisted by
previous experience as to my location) and acting accordingly.
It was also early for him to want a mouse, as judged by ex-
perience of the last few weeks. It may indicate a trend toward
increasing activity of the new cycle.
I now went into the cage to look up R5. He was up in his
retreat, but soon came down to sun his back on a perch about 5
feet from me, and was not disturbed when I moved about and left
the cage.
Rhody and R5 were now about 30 yards apart, engaged in the
same operation, without apparent knowledge of the other's presence.
12:15 Rhody has been in or near the glade ever since.
I succeed in getting
Rhody to sing.
At 11:45 I stood about 10 feet from him and koke-koked soft-
ly. After about the second trial he displayed his skin colors
without raising his crest. Before that he had appeared to listen.
On the next trial he drew his head back between his shoulders,
lowered his bill and said hroo--o-o-o-o in a deep, almost guttural
tone, rolling his rs. This occurred two or three times more.
He then essayed his first cooling song. He was now fairly off and
was still singing at intervals when I left, and his technique was
improving. His coo-song was often preceded by a little "grace
note" (?). His last note followed the one preceding by a long
interval--after he had raised and lowered his head again. It was
not really a coo, but more like the hroo above described.
Once or twice his voice "broke" on one of his coos, or, rather
had superimposed upon the fundamental tone a higher harmonic of
that peculiar "tinny" character I have tried to describe before.
I have not heretofore detected that preliminary note.
January 7th.
During the night the recording thermometer showed a minimum
of 27 degrees.* This is the lowest temperature shown here in the
ten winters I have lived here--with the exception of one night,
Dec. 12, 1932 (') when it went to 26, this being the coldest
cold spell ever known during the 60 years in which official
temperatures have been kept on this side of the bay.
At 9:30 (Temp. in court 34). R5 was sunning his back in the
upper extension.
Rhody doing the same at his post, where Mrs. Scamell saw
him at 9:20. (Did the cold make him leave his roost early?).
He would not come when I called him from the Clearing, so I went
*thermometer in park. See pp. 1357-58.
