White-throated
sparrow still
here.
Mar. llth.
Rain during the forenoon; only the outskirts of the reported storm, so far, and with little wind, has reached us.
About 11:10 A.M. I drove along the street by the west lot,
returning from an absence of an hour or so. Rhody was near his post
in the open about 100 feet away. I stopped and called to him. He
located me at once, although he could not possibly see more than my
called me at once, although he could not possibly see more than my
head, cried, then came to the edge of the bank. I got out and tossed
him a couple of dozen meal-worms, which he caught expertly one at
a time. He was perfectly dry.
A few minutes later I showed him the red box from the fence
at the Clearing. He ran toward me, came over the fence and had his
mouse, which he carried off with ceremony.
While the red color of the box, naturally, was not the entire
stimulus to which he reacted, it did not, at least, deter him from
coming, and sufficient instances have been cited in these notes to
show that the red-box has often proved the trigger that has released
action by him when he had been hesitating whether or not to come to
me. The object in referring to it here is not to attempt proof of
the effect of red color upon him--this one instance proves nothing--
but to draw attention to the contrast between his behavior in the
presence of red and that of Archie and Terry at a time in their
careers when red must have been a novel sensation to them.
While I was engaged with Rhody, Neo was singing loudly over
at the Robinsons'. I went to his nest and whistled Brownie's "purple,
one, two, three" call. This brought him home fro about 175
yards away, shortly followed by N2. He was given meal worms while
N2 watched. Soon he picked up a few soap-root fibres and took them
to his nest and sat there while N2 came for her share of worms.
Neo, about 6 feet to my right, now began to call loudly from the nest
in musical phrases. I think he could not see N2, who paid no visible
attention whatever until she had enough worms; she then joined hi
Both birds were dry; but Neo's tail is rapidly "getting no
better fast". Most of the rectrices are now broken off entirely and
appear as stubs of half their normal length or less. I can not be
certain that he has more than one full-length feather left in his
tail. This mutilation, together with the scarcity of feathers on the
back of his neck and general mussed-up appearance may be due in part
to his labors in thrusting passageway through tangled growth in nest
building; but I am strongly inclined to the view that it is mostly
due to fighting and that he has not had a clear field in his court-
ship.* (See back notes for example of thrashers pushing each other over
backward when fighting: something not good for tail feathers).
Neo and N2 both
in nest at
same time.
12:50 P.M. I went to the thrasher nest and was surprised to
see it occupied by a thrasher that apparently had a head at each end
of its body and no tail; Neo and N2 both in it at the same time,
looking solemn but comfortable.
An hour later only Neo was in the nest, but N2 was foraging
about nearby. (Calm, cloudy, 57°).
