full height and peer in all directions as if looking for his mate.
I cannot say that he imitated me, but his talk this time, due perhaps
to excess of imagination on my part, was modified at intervals with
a phrase--not previously recognized--that had more or less of the
rhythm and the intonation of the phrase repeated to him. After this
"lesson" he went out of the glade and took up a position behind me
about 25 feet away--still in the rain--and sang undersong, approaching
full song at times. Whenever he stopped, I was able to start him again
by talking to him and making "suggestive" sounds. This was kept up
with periods of digging and wandering about, for about three-quarters
of an hour. Except for the ends of their tails and beads of water on
their plumage, both birds looked dry. Their bills and feet were very
muddy with lumps of mud on the former. It is curious, but they do not
seem to mind these lumps at all.

9:30 A.M. (Temp. 51), heavy rain during the night. Neither

called softly off to one side and came out of the shrubbery for worms.
I again tried to get him to call Greenie with, perhaps, a little
better results than before. Certainly he used a phrase--not habitual
with him--that I am sure some persons might have considered an attempt
to repeat my words, and very obviously showed immediate interest in
locating something that was not in sight; for he again stretched up,
looked in all directions, called softly and ran off apparently to
conduct a search through the trees and bushes, finally winding up in
the top of the old oak (about 100 feet away), where he sat on a bare
stub looking off toward the south east, gurgling. I moved to the vicinity
of the dormitory tree to watch him. There was a sound of a bird
in or on the glass house in that tree and Greenie flew out, climbing
up to join her mate. Going to the glade I was joined by both birds,
