Snooty not at all.
Sept. 6th.
Up to about 8 A.M. the thrashers were in full song off towards
the glade, but I did not look them up until later.
Outer tail
feathers moult
first.
last.
It is the outer tail feathers of these birds that are moulted
last.
Their eyes are not circular in outline but oval (Not elliptical)
with the longer axis more or less horizontal and the "big end" forward.
The oval is not symmetrical about the major axis, as it is somewhat
flattened at the top. There is a small triangular patch of bare, almost
black skin to the rear of the eye. Their eyebrows project above the eye.
This shape, together with the setting, gives character to the eye; a sort
of keenness like that of an eagle.
Full song at
mid-day.
11:45 A.M. I had about decided this morning to note that the
thrashers used their full song at present only in the early morning
hours, when, on returning just now and coming out of the garage, full
song, ingeniously varied, was heard from the oaks west of the house. It
proved to be about 30 feet away. After listening for some minutes I
determined to identify the singer if possible. After calling a few times
the song ceased, the singer descended the tree, passed a quail which
the ground under
was sitting just below it, came along the bushes, climbed another tree
to get over a six foot wall, then came to me, still walking. All of this
instead of a short, direct flight through the air.
Sleeping
place (?)
6:40 P.M. Just went out to see if I had correctly spotted the
sleeping places of Brownie and Greenie for the coming night, but found
I had not. I thought I had them both located at 6 o'clock in their final
roosting places, but they had moved.
Sept. 7th.
The thrashers were in full song in the early morning. At about
7:30 they could not be found.
