Dacnis, Feb. 4, 1958, II  

they are strictly homologous with the Blue Honey creepers HCN's - more likely its "ordinary" CN's)

The circumstances in which these notes were given were not awfully clear. When I frist [[first]] saw the bird, a nearby group of Blue Honey creepers were uttering a lot of HCN's, and the Dacnis almost seemed to be duetting with the Honey creepers; but it continued its notes after the Honey creepers had shut up. This bird did not seem to be alarmed or hostile to any appreciable extent, so these notes did not seem to function exactly like the "Trit" notes of the Green Honey creepers. I rather wondered, in fact, if this female was not trying to "call in" her male?


Dacnis, I  

February 24, 1958
Barro Colorado

A single male Scarlet-thigh came to the dead tree by Chapman House this afternoon and gave a lot of notes, apparently some sort of CN's. Without any ritualized postures or movements. The notes themselves were longer than any I remember hearing from Dacnises before, almost bisyllabic. Usually more or less like "Tree-eee"; perhaps sometimes like "Treee-you" [[sketch of notes, approximately "–– __"]] Rather plaintive. There were perhaps most reminiscent of some of the plaintive CN's of the Thraupis tanagers–the ones that I think are used to "call in" the mate. Anyhow they produced no response in the case of this Scarlet-thigh and he eventually flew off and disappeared.
