Aramides cajauea, July 5. 1960. IV         

still. I don't know what these meant.

This evening I ran off some more experiments with a couple of other birds.

WR remained silent for quite a long time when handled very roughly. I am now coming to the conclusion that a badly frightened bird always or almost always does remain quite silent.

Finally, as the handling continued, the bird uttered 2 chirps. These were very loud and harsh.

Then it started to utter loud LC notes almost immediately upon being isolated, (in a box).

Uttered peeps as greeting: The first greeting peeps were short & fairly soft. The later ones were relatively long and plaintive, like those uttered by all the birds when they are together in their cage. I continued to talk to the bird for quite a long time, uttering a series of not-very-rapid "Hello"s. The bird continued to respond by peeps. Finally, it also responded, twice, by performing a Tsh just after I uttered a "Hello". Each Tsh was accompanied by a single relatively long and plaintive peep (I think I shall call these "PP").

Then I reached my hand into the box to start to pick it up. The bird tried to run away, and began to utter very long and loud peeps. Quite shrill and high-pitched.  Not  plaintive. There were probably essentially the same as the "Alarm Peep's" of U described above on June 30, 1960, p.16. The individual notes were so long, however, that they whole series did not give the impression of being uttered very rapidly.
