Aramides cajauea, Sept. 7, 1960 II       

but the actual repertory itself is probably not very different!!

As soon as the birds get used to my presence, they fall silent and remain that way. Start to feed quite peacefully.

The birds start uttering 00 notes again as soon as I start moving around. Then, when I go into their cage, they continue to utter 00 notes while running around madly, trying to escape from me.

I finally catch one of the birds. At the moment of capture, it utters a lot of clucks and 1 squawk-like chirp (this might even be called a pure squawk-tout court - now). After being held a while, the bird subsides a little, and utters only clucks (not quite as rapidly as before).

I then put this bird alone in the isolation cage. It runs about quite silently, usually in the pre-ck posture, occasionally performing ck Movements, as long as I just stand still and watch it. Then, when I start to move around, it starts to run more vigorously and utters a few 00 notes (still in the pre-ck posture, performing ck Movements quite frequently.

It is obvious that the ck patterns are either lower intensity and/or contain a weaker escape component than 00 notes.

This bird remains silent for 15 minutes after I leave it along in the isolation cage. Then I have to chase if a long time in order to catch it. When first chased, it utters a few 00 notes while running. Then runs silently for a while. Then utters one squawk-like chirp when the chase is at its peak of vigor. Then runs silently again. Finally when caught and handled, the bird remains quite silent.

So the complete vocal repertory of the birds now would seem to be 00 notes & clucks & squawk-like chirps (or squawks).
