Rhamphocelus [[Ramphocelus]], May 5, 1960, II          

"Auh" Notes is that the male interjected an occasional typical "Auh" Note in the midst of these more distinctive notes this morning.

I shall call typical "Auh" Notes "ACN," typical Psseeet" Notes "PCN" and these peculiarly thin and every "AuH-like notes "APCN."

The male's series of notes this morning when the female went down to feed was approximately as follows: APCN-APCN-APCN-APCN-APCN-APCN-APCN-ACN-APCN-APCN-APCN-APCN-APCN-APCN-APCN-APCN-APCN-APCN-ACN...........

(The alternate "Pssseeet" - "Auh" performance of the male on May 1 must have been largely alternate PCN & APCN, with very little or no ACN.)

This APCN with occasional ACN performance must be closely related to the PCN-APCN performance the male did on May 1. I rather imagine that the APCN must be intermediate in both causation & function between typical ACN and typical PCN. (The other captive male Sangre de Toro uttered ACN's while the A male was uttering APCN's with occasional ACN. I think that this other male began his ACN's after male A began his APCN's). It is possible that the ACN's contain a stronger hostile component than the PCN's.

Male A stopped his APCN-ACN performance as soon as the female flew up again after feeding — and resumed "Keeyoo" singing as before. Later on he uttered bursts of APCN's again from time to time, in spite of the fact that the female was sitting on a fairly high perch or flying around the cage at the time. It may be significant, however, that he usually uttered these APCN's while he was hanging on the side of his cage nearest to the cage of the other captive male Sangre. Their performances may have been provoked by the other male.
