Aramides cajauea, June 30, 1960 III

WB utters Peeps and chirps when handled. Remains silent at first, and then utters Peeps, when isolated. Then utters LC Notes as isolation continues.

Then utters Peeps, accompanied by Tsh's accompanied to tsh (see below), as greeting. Again.

Then utters short but not rapidly repeated Peeps when running away from me.

Then utters the same type of Peeps when following me (very briefly and badly).

Then utters a few single, rather chirp-like, Peeps when frightened. Then utters both Peeps and Trills when poked.

WR. Utters chirps when handled. Then utters LC Notes immediately when isolated. Then utters ordinary Peeps (quite like those uttered by all the birds a few days ago.)as greeting. Then utters similar Peeps, perhaps somewhat louder & more rapid, when running away from me. Shows no tendency to follow me. Then utters 1 Trill (?), followed by lots of chirps, when poked. Then utters ordinary Peeps when frightened.

Both WH and WB performed quite a lot of single Tsh's when isolated at various times. Usually or always silent in such circumstances ((?) also account of WB above). These movements did not appear to be ritualized or exaggerated in form, but I have not noticed the in such circumstances before, and I think that they may have been produced by something other than "comfort" motivation.

The fast, repeated, lateral head-shaking or trembling performed by birds held upside down or on their backs seems to have disappeared almost completely now. Apparently, it was not a signal of any sort.
