cation of activated gregariousness. (The PAG movements are usually rapid, but they are not very usually forceful.) And the birds always remain quite silent during "Oooooo" reactions.
  (I forgot to mention that once, when Hrr had been standing in TV before I began to utter "Ooooooooo"s, he immediately lowered (underlined) his tail when I did utter the sounds.  This would seem to be conclusive proof that the "Oooooooo" reaction does not contain an appreciable escape component.)
  After their (?) we separated M & Hrr, taking Hrr to a cage about 200 yds from the one in which M stayed (where they have both been living for some weeks now.) Both birds remained quite silent for a period of over 20 minutes.
  They both, however, assumed TVC immediately after being separated. This would suggest that the TVC is now a high intensity alarm reaction - higher intensity than the TV.

Usually in slightly distinct series of approximately 4 notes:
