down the branch away from the ♀. The ♀ usually or always continued her St & Q (with or without soft Bzz's) until the ♂ did BW and/or until he retreated, but then she would stop without further display.
It looked very much as if the ♂ got "cold feet" whenever he got too close to the ♀.
The BW at the end of sidling and display performances would certainly appear to have been an indication of very strong frustration of some sort.
It may be significant, in this connection, that the ♂ interrupted all his other activities, quite early in the morning, to perform a lot of comfort activities, for 2 or 3 minutes on end. This long burst of comfort activities did not follow immediately after sidling and display toward the ♀; but it did begin with quite a lot of BW movements, followed by intensive preening of both wings (the wings were stretched out and downward during preening, in a manner which appeared to be perfectly "normal" but did increase the amount of black visible in the plumage of the ♂ to a very considerable extent.)
The whole behavior of these birds would suggest that the ♀'s sex or pairing drive was relatively stronger than that of the ♂, and that the ♂'s hostility was relatively stronger than that of the ♀. If so, this might suggest that the Soft Buzzes are largely hostile, and that extreme Q is largely or at least partly sexual
The ♂ did not appear to be very aggressive. It is obvious that the "forward"-type St's are not always relatively aggressive. Just include a strong intention movement of advancing component. 
Gradually the displays between the 2 birds died down alm
