Rhody's first song
of the season due
first week in Jan-
uary.
Thrasher song
every day.
Based on the precedent of January 1937 and 1938, Rhody's
first song of the year (and the first in many months)
should be heard the first week in January 1939, at which
time, presumably, his gonads should be far enough advanced
in activity to be pouring sex hormones into his internal economy.
During this period Neo and his mate have been frequently
contacted and given worms and Neo has sung every day. Song
has usually been first heard about 7 A.M.--sometimes earlier.
December 30th. (Sunrise 7:25; sunset 4:59).
From the preceding paragraph it will be seen that thrasher
song has been anticipating sunrise by a considerable margin.
Day dawned somewhat hazy, but mild, with fog at lower eleva-
tions.
By 10 o'clock I had given worms to:
Rhody, sitting on the west fence and taking them from
hand,
Neo and mate in the orchard--Neo singing thereafter,
"Spots" the spotted towhee, who has become a persistent
applicants
A song sparrow, for the first time,
A Nuttall sparrow--not the first time; probably the
same individual each time,
A hermit thrush. Probably also a repeater.
December 31st (Sunrise remaining constant; sunset 5:00).
Yesterday and today Rhody had one mouse and slept in No.l.
Thrasher song song continues to be heard at various times
during the day, beginning about 7:10 A.M.
Weather remains fair and mild.
