Rhamphocelus [[Ramphocelus]], Mar. 3, 1959, II        

The adult male (at least) also uttered quite a lot of single "Auh" CN's as it flew around.

Rhamphocelus [[Ramphocelus]], I.

Cerro Punta

Saw another party of 1 adult male and 2 females and/or young Scarlet Rumps today, right outside El Volcán. This time the male uttered nothing but "Trit" CN's, while one or both of the other birds uttered "Auh"s.

There are a lot of Sangre de Toros around here, which I have watched from time to time, in the intervals of studying other things. They seem to be quite active. There are a number of young birds around, but some of the adults are also showing some patterns which I have not seen before.  It is probable that they are in the full swing of the breeding season now.

For one thing, a lot of birds are uttering notes which appears to be a form of "Trit" CN, but which should actually, in the case of this species be transcribed as "Psssssst." Very Latin American! I shouldn't be surprised if all sorts of birds, males and females, adults & young, uttered such notes from time to time, and they are certainly occasionally uttered by birds moving through low brush & shrubbery, but the only birds I have actually been able to see uttering these "Psssssst" CNs are adult males always when sitting alone  near the top of a tall tree.
