ning to be heard in Sampson territory. His exoduses, in so far as
they were observed by Dr. Reynolds, leads him to believe that the
Sampson thrasher is really Pat. From the relative tameness of that
bird (perhaps absence of wildness is better) I am inclined to agree,
especially as this is the first time that a thrasher has paid more
than a fleeting visit to the Sampson place.
March 13th.
The first two paragraphs of yesterday's notes apply equally
to today, with the addition that Rhody is getting still more keen
on the job.
About 5 P.M. he left his post at the front porch of this house
and started apparently for his roost. Since about 8:15 A.M., when
he took up his post on the observatory tower and called until about
10 A.M., he has been wandering about searching everywhere, including
this room about 20 minutes ago, calling, listening and scanning the
surroundings near and far. In the aggregate he spent probably 3
hours on the roof, having been up and down repeatedly. There have
been several new manifestations by him today, not observed before.
First: a single low-pitched, very soft call made without low-
ering his head, audible perhaps 30 feet if everything else is quiet.
Something like: Hroo or hrooh. A pigeon-or dovelike sound.
Second: a four note call of similar notes, gradually rising in
pitch, the fourth drawn out longer and vibratory seeming to contain
palatal r-r-r-rs. This is also soft and low and is made without
lowering the head also.
Third: a new display consisting in taking a few steps forward
on the ground, straightening up while in motion and striking the
backs? of the wings together three or four times in succession.
When first seen and heard I thought he was striking his sides, but
nearer view showed that the wings met behind his back. This makes
a loud sound, but less sharp than that made by a pigeon.
