Aramides cajauea, July 7, 1960, III 

away from me. Sometimes silent. At other times uttered the same form of RP described immediately above.

Then I started poking it. At first it remained silent when poked, and then began to utter single peeps. These peeps became more & more chirp-like as the poking continued, and finally developed into perfectly typical chirps.

This morning, I happened to go by the Wood Rail cage, and looked at me alertly (without assuming any special ritualized posture),performed about 4 rapid ck Movements, and then ran away from me. This would seem to be a further indication that the ck continues (?) a strong escape component.

The birds behavior has changed very little, in spite of the fact that they are becoming quite well-feathered now. Except that they are becoming shyer and shyer, (this increasing shyness may be largely or completely due to the fact that we have not been with them very much recently.)

They still give the same PP when all together in their cage.

I tried the usual series of experiments with 2 birds tonight. WH remained quite silent, for a long time, when first isolated (in a box). Then uttered 1 chirp, and assumed a definite SC posture.
