(?)              Sept. 27, 1960, II.   72

  Then we put WH2 in another cage, the cage of the 4 birds of the first (?). They immediately began to chase it. No display movements or postures by any of the birds. WH2 just ran away from the others in the usual running posture.  Whenever one of the others birds caught up with WH2, it just tried to peck WH2.  Pecks usually directed to WH2's head.
  As soon as WH2 was put in his cage with the other birds, one or more birds started to utter clucks. Not fast (there are a few lines here)etc. Much slower than the usual clucks of birds held in the hand. I think that it was WH2 who uttered these clucks.
  Every time one of the other birds pecked WH2, or even before, when one of the other birds seemed to have WH2 covered, WH2 uttered 1 or 2 chirp-squawks. (probably but classified as squawks.)
  We had to remove WH2 after only a few minutes.
  We then left the birds alone for a while. 
  Then we came back to the birds of the first clutch. One of them uttered 00 notes when I first approached, and the other 3 remained silent.
  Then we did a little experimenting.
  I.
  Silent when chased, at least at first (after the chase had continued for quite a long while, one of the birds in the cage - I don't know which - uttered 1 or 2 clucks). Then, when I was almost caught, it uttered a few squawks. A few seconds later, however, when it was really caught, it remained quite silent - even when struggling violently. Then we put it in the isolation cage. Remained silent there too.
  II. Silent, then 1 squawk when chased, Silent when caught. Then began to utter rapid clucks __ __ __ __ __ ___ ___ ___ and squawks while struggling in hand. Then silent again when passive
