he returned to his same singing post and resumed song, facing east,
while N2 was still present. It would seem, then, as if the singing
was not a call for his mate, but announcement of his occupancy
of the territory.
5:35 P.M. During the elapsed time we have had two more hail
storms accompanied by strong winds, and several heavy rains of short
duration. In between it has been calm and sunny.
Rhody promptly sought the shelter of his roof under the old
oak each time. When it hailed he watched the hail-stones bouncing
in front of his retreat with manifest interest unaccompanied by fear.
Thus he would stretch out his neck, lower his head close to the ground
and look at the stones with first one eye and then the other.
The thrashers stayed home most of the time.
At 2:45 Rhody was given a mouse, which he carried for only a
few minutes, then ate. At 3:20 I was surprised to find him behind
me crying. It could only mean that he wanted another mouse, so
I started for the tool-house just as another flurry of hail commenced.
Rhody followed part way, but sensibly ran to his shelter. Here he
received the mouse with full honors, eventually eating it in his new
nest at 4:20.
At 5:30 he was still in his nest--unexpectedly.
At 5:55 he had left for his old house in the roost tree; so
nest l-38 is still a nest and not a sleeping place .
About 6 I whistled for Neo. He came promptly through his
hole in the fence, ignored my offers of worms, ran past me and climbed
an oak behind me, where he began calling quilk, quilk, quilk, the
shortened form of the thrasher queelick. Brownie and Greenie used
both, but I do not now recall having heard either Neo or his mate
use either up to the present--in fact I have been wondering for many
days why this fairly common thrasher call has been missing from the
"vocabulary" of these two birds--and for that matter, am still wondering.
Neo soon changed this call to the more common scrip, then followed
with full song for about 5 minutes; when he flew toward the
west. His song was the most varied yet heard from him, containing
many unfamiliar phrases, some of which were strongly reminiscent of
Brownie's, but to my ear, not precisely the same.
Mar. 14th.
A sunny morning; the storm seems to have passed, much I imagine,
to the satisfaction of everything that has a back-bone except,
perhaps, fish and amphibians!
Neo's song was heard to the west about 6:30 A.M., moving
closer. About 7 he was regaled with Hamburger by Julio. At 7:20
I found him sitting quietly in his nest.
At this time Rhody was warming his back at his post on the
west lot and interested in my efforts to make him sing only to the
extent of raising and lowering his crest and looking at me over his
shoulder.
At 8:20 the occupant of the thrasher nest was N2, also sitting
quietly as if meaning business. Neo was absent, but thrasher
song sounded off to the N.E.
