Aramides cajauea, July 30, 1960, III.   

I am not sure about this.

While the birds were moving about & feeding, they also uttered quite a lot of typical LC notes. Usually or always uttered by a bird which had become "separated" from its companions (i.e. was 2 or 3 feet away from its companions). Probably not accompanied by ck Movements.   

At the same time, possibly in much the same circumstances, the birds also uttered some notes which may have been more or less distinctly different, in motivation and/or function, from typical LC notes. Sounded quite like typical LC notes, but definitely bi-syllabic.  Might be transcribed by something like "Whee-hoooooooo"

It is possible that these notes represent the "beginning" of a new type of call. Jimmy Ambrose first noticed them yesterday.

When I sneezed rather suddenly, all 4 birds ran to a corner of their cage and crouched silently. Their crouches did not appear to be ritualized in form.

Later on, when all 4 birds were standing or sitting closes together apparently quite relaxed, they remained absolutely silent.

We ran some tests on all 4 birds immediately before )sitting in the cage to observe their behavior all together.

U. We began by taking U out of its cage, and putting it in another similar cage, by itself. Not in a box. It could see both us and its companions quite clearly. In these circumstances it uttered a lot of peeps. Quite long and plaintive. Probably a for of PP, but not quite as long as typical PP notes.
