[[underlined]] Cyanerpes [[/underlined]] Feb. 21, 1958, I

which I will only be able to keep temporarily. Have put it in the large aviary.
The commonest note of this bird is a loud CN, much like the ordinary CN of the Blues in quality, but much louder (Mrs. M. also describes it as more metallic). Often uttered in long series. Often accompanied by WF's and TF's; but [[underlined]] never [[/underlined]] any CR. I think that many of these CN's may well contain a relatively strong escape component. They were uttered very commonly by the bird during the trip from Balboa to BCI; and there was another long and rather rapid burst of them just now when I entered the aviary.
These  CN's would certainly appear to be homologous with the ordinary CN's and/or the HCN's of the Blues.
They may be sharply distinguished from a suddenly and greatly accelerated burst of notes which seem to form an R. Each "syllable" of the R is apparently identical with a CN; but they are much more rapidly repeated than the notes of even the most rapid series of CN's I have heard. (I.E. there is a discontinuity here. This R pattern of the Shining Honeycreepers is very reminiscent of the R's of the [[underlined]] Tangara [[/underlined]] tanagers in sound; and also in the way it obviously seems to be derived from a rapid series of ordinary CN's, and yet has become sufficiently ritualized, is itself alone, to be considered a distinct pattern by itself alone.)
The R of the Shinings may be introduced by 1 or 2 preliminary CN notes; in which case the R does indeed appear to be a literal acceleration.
I presume that the R's are at least partly higher intensity than the CN's. They sometimes appear to be the "climax" of a burst
