Aramides cajauea, July 30, 1960 IV  

Then we put the bird in the usual isolation box. First it uttered a few undistinctive peeps, quite soft and short. (I shall call all undistinctive peeps "P"s tout court, from now on.) Then began to utter typical LC notes.

I talked to it after it had uttered 6 or 7 of these LC notes. It did not perform a real greeting. Just uttered more LC notes, intermingled with P's.

Then it flew out of the box. Stood for a few second, performing may ck Movements. Then it started to move around its cage. Performing more ck's.  Largely silent during this walking. Only occasionally uttered a few P's, PP's and very weak & soft LC notes.

Went into a typical SC posture when I approached it.  Accompanied by a few weak, not very loud, AlP notes. Then started walking around again when I retreated. Uttering P, PP, and LC notes as before, with frequent ck Movements. Then down into SC with AlP notes when I approached again.

I then picked it up and handled it quite roughly. It remained absolutely silent throughout this handling.

Then I put it down on the ground and chased it a little.  It uttered PP's, AlP's, and one brief burst of typical (i.e. relatively slow) RP2, during this chasing.  Then I let it rest a minute, and then approached again.  It went down into SC and uttered AlP's as usual.

These AlP's and many of the AlP's it uttered earlier today were not very different, in sound, from PP's. I was again impressed by the fact that the series P-PP-AlP - chirp appears to be almost a continuum, at the present time.

Then it uttered AlP's and some RP2 when poked.
