Dacnis, June 22, 1968, I     

with a low "forward" posture (F.) This alternation was very rapid, rigid, and obviously ritualized as such.

Looks rather like a ritualized form of the more variable "bowing" of male Blue Honeycreepers during some disputes. The whole thing apparently quite silent.

When the birds all flew away quite suddenly.

Dacnis, I   

April 26, 1960
Barro Colorado

I bought a pair of Blue Dacnises (1 male & 1 female) in the market yesterday. I now have them in a 3 foot cage, by themselves, in the animal house. They appear to be in quite good health (the male has lost his tail but is very vigorous. The female is in nearly perfect plumage but somewhat less vigorous). Quite tame.

One or both birds (possibly only the male utter single "Trit" CN's from time to time. Quite soft and weak-sounding. Not at all harsh or hoarse or metallic. Not accompanied by any special ritualized postures or movements.

At dawn this morning the male uttered 3 separate, single, phrases of "warbling" song. Very jumbled and difficult to hear clearly - although not really very soft. The last part of each phrase seemed to be a doublet. Perhaps something like "Tree-weee"? It is possible that the rest of the phrases were also doublets, although less distinct. Probably something like 6 or 7 notes in each phrase. As far as I could tell, none of these songs were accompanied by ritualized postures or movement
