Cyanerpes, Feb. 21, 1958, II     47

But the R's may also contain a relatively stronger attack component than at least some of the CN's.  The captive [[female symbol]] did not give her first R's until this morning, when she was getting used to her travelling cage (i.e. her escape component was probably becoming relatively weaker).  She also did more R after I left her loose in the aviary the first time, in the midst of all the other birds; when she seemed to be quite hostile but not overwhelmingly panic-stricken. And the R was also done by the [[male symbol]] of a visiting pair.
This pair came to visit the aviary briefly very shortly after I let the captive [[female symbol]] go. Do you imagine that there are lots of Shinnings around all the time, although one doesn't see them very much?
The [[female symbol]] of the visiting pair didn't seem to do much. Just sat and stared the [[male symbol]], however, alternated lots of CN's with many series of R's. He may also have uttered a few Bzz's - see below - but I can't be sure of this, as the captive [[female symbol]] certainly uttered some Bzz's at this time) I didn't get too good a view of him, as everything happened very fast and leaves were in the way; but he certainly uttered almost all his CN's and some of his R's from an apparently perfectly unritualized posture (no CR, and even very little fluking), just uttering and peering more or less forward (neck probably inclined slightly upward, head & bill probably pointed slightly downward) But during some of his R's he turned to the [[female symbol]] in a posture roughly [[connsin?]], and stood in this posture very briefly. Was this redirection? And is it really homologous with some of the posture-
