The adult Black [[male symbol]] uttered one burst of 3 or 4 Squ or Squ-like notes today, after an outburst of all sorts of other calls. As noted above (p.38),  these might be low intensity indications of almost anything. I do not think that the Squ's of adults should be considered a separate distinct pattern. (These Squ's of the Black male were quite like those of young animals in actual sound but louder and harder. ) 
It might be convenient, at this stage, to list all the displays known to be performed by adult Blacks, including some patterns which might not be very distinct or typically adult.

This list is almost certainly not complete. It does not, for instance, include some of the patterns known to be performed by adult Reds, i.e. OCB and LSH (see below); although I rather imagine that the repertories of the Blacks and the Reds will eventually be found to be qualitatively identical. The motivation of these patterns may be represented by the following
