nothing unusual; which, of course, as far as they are concerned, is
probably a fact.
Jan. 23rd.
At 10 A.M. (It is now 10:15), I went to the glade--no birds
there--a low fog or drizzling drain--I do not know which. Brownie
came from outside without being called. As the chairs were too wet
to sit in, I squatted on the ground and handed one worm at a time
to Brownie, urging him to call Greenie. Between worms he would
mount part way up a Baccharis bush and look fixedly toward the S.E.
I kept urging him to call Greenie and finally he climbed up into the
to a point
oak underneath which I crouched, about 3 feet higher than my head and
about 8 feet behind me, turned his back to me, looked searchingly
loud
toward the S.E. and broke into a series of loud melodious calls,
working up into each gradually from almost inaudible notes and using
many of the phrases already noted. He gave every appearance of con-
cern as to the whereabouts of his mate and finally dived over the fence
down into the chaparral as if looking for her. I then left, as no
other birds came--not even the wren. There can be little doubt that
he was calling his mate; whether I had anything to do with it is open
to question; but the incident is altogether too pat, in my belief, to
be entirely fortuitous.

I neglected to note yesterday that, while Brownie was sitting on
my knee, his upper eyelids were frequently winked, often without moving
the nictitating membrane noticeably, or as I think, at all. Apparent-

ly the thrasher is one bird that is an exception. (See Encyc. Brit.,
11th. Ed., p. 967: "Of the outer eyelids, the lower alone is movable
in most birds, as in reptiles,...". The latest edition of this work,
the 14th., is much more sketchy in its article on birds than the
older one cited; evidently commercial considerations are becoming
of more and more effect in this work as time goes on).
