calendula, R. satrapa [Regulus satrapa], Zon. albicollis [Zonotrichia albicollis],
Pooectes gram [Pooecetes gramineus] & Spiz. pusilla [Spizella pusilla]
(several). Saw numbers of T. pallasii [Turdus pallasii];
they were unusually active & noisy
and uttered in addition to the cluck
a plaintive whee, wheep, which I 
never heard at this season before.
Junco hyemalis is now excessively 
abundant and I saw flocks of 50
or more to day. The chirp of D.
palmarum [Dendroica palmarum] is not unlike that of
D. discolor [Dendroica discolor] or D. aestiva [Dendroica aestiva], & quite different
from that of coronata [Dendroica coronata]. Buteo borealis
is beginning to appear over its old
haunts, Autumn is perhaps now
at its fullest perfection and the woods
are everywhere perfect canopies pf 
gold , russet and crimson.

frosty Oct. [October] morning while waiting for
the ducks to come in. A few moments
of careful attention & criticism convinced
