149 Ramphocelus, I May 5, 1962 Barro Colorado Arrive to watch same birds as yesterday 5:55 a.m. All quiet when I arrive. Then birds begin to fly about a little 6:07. Silent female by far the most active. One male supplants the other, without display. One male, presumably the New male, is sitting in moderate FH much of the the time. 6:05 a.m. Birds disturbed by appearance of Alvarez, collecting food cubes[[?]]. Old male and/or female utter(s) TssN's a few Φ and then NN's. One male utters brief rasping R when landing beside female. Flies away again immediately. One male, almost certainly New, utters several Φ's (complete with prelim note) while perched on branch about 1 ft from female. In FH posture while he utters these patterns. Female flies far away. Male immediately switches to uttering TssN's. Still in FH. Then flies away himself 6:15. Then new utters another Φ when landing beside female. Again in FH female flies away. Male utters a few more Φ, then switches to TssN's. Uttered in regular DC-like series. In not very extreme FH (Head rounded, not obviously ruffled). Somehow the New male has become the dominant male. Old male is quite silent now, 6:18, flying around rather nervously. New male still uttering TssN's. Birds begin NN's when Alvarez enters cage, 6:20.
