Aramides cajauea, August 2, 1960, II     

well represent the beginning of RP, but none of the series uttered by WH2 this morning were as rapid, or as long-sustained, as the well developed RP1 of the chicks of the old clutch.

WH2 also uttered P's and chirps when poked. Still no trills.

WR2 Was put on the floor like WH2, and tested in the same way. It followed me quite well at times, but also ran away from me at other times. (This being the third chick to hatch, it is not as well fixated on me as WH2. It is partly fixated on its companions instead.) WR2 uttered P's both when following and when running away from me. In both cases, the P's were sometimes uttered in accelerated series. Some of these series were more rapid and longer than anything uttered by WH2. The most rapid series uttered by WR2 were uttered when it was running away from me. Because it was more [[determined?]] when running away? Or more hostile???

Like WH2, WR2 uttered P's and chirps when poked. No trills.

Neither bird made any real attempt to run away when poked.  This might help too explain why the did not utter trills in such circumstances (if the trill & RP patterns are really closely related.)

All 3 chicks seem to be doing well - although WB2 still has its [[?]].

Two of the new chicks, WH2 and WR2, seem to be flourishing. (But we decided to dispose of WB2.
