long bursts of many short notes. Either RP and/or trills.

WR2
No crouch when first approached. Uttered a few chirps when handled. Began to utter LC notes immediately when put in isolation box. Then starts silent jumping. No crouch when I put my hand in the box. Then we put the chick on the floor. Would not follow us. Just stood and walked around, uttering occasional P's and LC notes. Then utters chirps & P's when poked.

Aramides cajauea, I.                

August 14, 1960
Barro Colorado

This afternoon, when I went near the cage of the new chicks, they uttered series of fast, rapid, notes, RP's and/or trills.

This evening, when I first went near their cage, they uttered a few longer notes. PP's and/or LC notes.

I was struck by the thought that some of the notes uttered by the first-clutch chicks which I called PP's may have been closely related to AlP's.

Later this evening, when I approached the cage again, both chicks uttered P's (moderately long notes). One of them also uttered LC notes. The other also uttered chirps (these chirps were not very harsh, but they were fairly distinct from AlP's.

Then I ran the usual series of tests on both birds.

WH2 Uttered RP when approached.  No crouch.

Then uttered LC's immediately upon being isolated. Continued to utter LC notes, without change, when I spoke to it.

I put my hand into the isolation box. The bird did not respond
