Cyanerpes[[underlinded]], Feb. 21, 1958, IV      [[page number]] 49
Early this morning, while still in her travelling cage, the [[female symbol]] uttered a burst of R's, which were fluctuating and interrupted in such a way that the whole thing was slightly reminiscent of a "rattling version" of the ws's of the young captive [[male symbol]] Blues.  She has not done this again, however, so it may not have been significant.
I have caught a lot of Blue Honey creepers this afternoon, in my unavailing efforts to catch the Shinings. Several [[male symbol]] Blues have uttered long hoarse screams when handled. These are similar to the HCN's and WhN's in quality but much longer and louder. I shall call them HSer.  Must be very high intensity, and probably contain an appreciable attack component, (as these birds try to bite when handled!)
I think the usual low intensity series of WhN's, unaccompanied by ritualized postures or movements (except, perhaps, a trace of St and/or CR) is made up of only 2 notes "_ _"
Watching the [[female symbol]] Shining this afternoon, I am rather coming over to the idea that R's can develop quite smoothly out of a series of accelerating ordinary CN's.

There were no visits by wild birds for a long time this morning, and the [[female symbol]] Shining was relatively placid as compared with yesterday. It may be significant, therefore, that she gave lots of CN's, and lots of Bzz's (when other birds came too near), but no[[/underlinded]] R's, during this calm period.  Would suggest that R is definitely higher intensity than at least some of the other notes.
