Pezopetes, Oct. 4,1960. II  

NOTE: SN's not the same as the SN's of Thraupis & Tangara. 

loud, whistled but definitely metallic notes, each note being briefer than the LW's, but the successive notes repeated much more rapidly one right after the other than the preceding LW's had been. Each note of this type might be transcribed by something like "Kleee." (I shall call such metallic notes "MW".) This series of MW's was followed, immediately, by a series of soft, hoarse, notes. Each one of these soft notes ("SN") might be transcribed by something like "Tsuwah" or "Tsawah." They were also repeated one right after the other. The whole effect of this series was rather twittering, very much like the Wbl of the Yellow-thighs. These notes also had a rattle undertone, however, so they were also reminiscent of some of the soft R's of Yellow-thighs. This whole vocalization might be represented as follows:

Then the birds started to hop around in the bushes, and uttered this MW-SN vocalization several times more. Just as before in sound. Probably uttered each time one bird joined the other.

I could not tell if these MW-SN "greetings" were being uttered by one or both birds. Possibly only the bird (male?) who had uttered LW's previously.

 As far as I could tell, these MW-SN "greetings" were not accompanied by special movements or postures. Probably only slight CR.

After the first MW-SN "greeting" one of the birds began to utter more variable song phrases. More or less similar phrases were then intermingled with the later MW-SN vocalizations, in an apparently random manner. I think all these song phrases were uttered by the same bird, the bird who uttered LW's before.

These songs were so extremely rapid and variable that I cannot describe them very well.  Seemed to consist, eventually, of a few doublets of various
