Aramides cajauea, July 12, 1960, IV           

Then I started to poke the bird more energetically. It reacted at first by uttering chirps and AlP's. Then, when I continued poking, it began to utter a few trills in addition to chirps and AlP's.  These trills usually occurred just when the bird was able to run a few inches away from me, between pokes. Another indication that the trills are closely related to "RP."

When I frightened the bird by stamping my foot, it ran away, uttering the same type of soft "slow RP" as described above.

U remained quite silent when handled.

The isolated in box. Immediately starts to utter short, soft, single peeps, at long intervals. Then starts LC notes.

Utters PP as greeting when I talk to it.

Then utters chirps and AlP's when I put my hand into the box. These were accompanied by overt escape movements and/or SC.

Then I put it out on the floor.  It stood, without running or walking, for some minutes. Performing repeated ck Movements, and 1 Tsh, all quite silent. Twice, it stood in an extreme "Alert Posture (see next page), for several seconds each time. Also quite silent. I don't know what provoked these Alert Postures- possibly something the bird saw outside the animal house. I cannot be sure that these Alert Postures were ritualized, but they were certainly very extreme, and I have never seen anything quite like them before. Their sudden appearance is somewhat reminiscent of the sudden appearance of ck Movements. No ontogenetic ritualization here either.

hen the bird started to run around the floor, mostly away from me. Uttered typical or fairly typical RP when running. Intermingled with occasional PP notes, especially when standing still or, at least, not running very fast.
