successive notes; but the animals occasionally uttered more complex calls which seemed to be series of Q Notes uttered much more rapidly, without appreciable pauses between the notes.  Sometimes gave a sort of "bubbling" effect.  [[underlined]] Very [[/underlined]] reminiscent of the TW of the Puiche's!!  I shall call this pattern QTW in this species.  Usually or always included at least 4 notes, sometimes more, perhaps a lot more in a few cases.

Both the Q and QTW were usually or always accompanied by some trace of BT, I think.  Or rather, the animals which were doing BT before continued BT while they gave Q and/or QTW, and continued to do BT afterwards.  

Both Q and QTW were usually or always combined with Jud also.  And they were also combined with other obviously aggressive movements as well.  The usual sequence of events was for an animal which had been looking at us for some time with silent BT and perhaps some trace of Jud to suddenly rush a few feet closer to us, stop, and perform extreme Jud, uttering Q's and QTW's as it rushed forward and did the extreme Jud.  This type of behavior would seem to indicate conclusively that both the Q and QTW are quite aggressive.

Both the Q and QTW (the QTW possibly even more than the Q) were quite remarkably contagious.  Whenever one [[bird?]] would start these calls, one or more of the other animals in the neighborhood would usually start them too.  And the most interesting aspect of the contagiousness of these patterns was that the other animals which responded by giving Q and QTW also usually ran closer to us as they gave the notes and performed particularly vigorous Jud.  The round of the Q and QTW, in other words, seemed to stimulate the "general" aggressiveness of the animals which heard them, and may have actually "orientated" their aggressiveness for them!

I am not sure what the causal differences between the Q and QTW may be.  It is possible that the QTW is just higher intensity than the simple
