[[underlined]]Cyanerpes[[/underlined]], I        56[[circled]]
March 2, 1958
Barro Colorado
More behaviour as before near the captive [[female symbol]]. In particular, I noticed some fights between the wild [[male symbol]]'s. As usual with R's, Bzz's, and silent St's (with BL and B fluff).  I am now certain that the St pattern is usually, and perhaps always, silent.  I have also seen a [[male symbol]] in an unusual St and B fluff posture which seems to confirm the relationships of this pattern to the U fluff of the Greens.
In the case of these Shinings,this may be just a low 
intensity form of the more extreme St + BL pattern).
One thing I have noticed about both the [[underlined]]Cyanerpes[[/underlined]] honey-creepers: they are both extremely clever in avoiding the mist nets (in strong contrast with the Greens which just pile in pell-mell, one right after the other).

The captive [[female symbol]] Shining did her usual peculiar "singing" this morning, i.e. repeated R's and Bzz's, and I was able to confirm the fact that some of her single R notes were unusually flute like , less sharp and abrupt than usual. This is what makes the whole performance sound so much like the WS of the Blues.  I should be inclined to think that the WS of the Blues was derived from some such performance - were it not for the fact that so many other tanagers have WS's.
