324 BIRDS OF THE REPUBLIC OF PANAMA — PART 3 



between adjacent perches at the same level. . . . During these flights 

 a soft flip-er flip, probably a wing noise, could sometimes be heard. 

 ... (2) Occasionally the bird would quickly turn about on its perch, 

 so as to face the other way, without any lateral movement along the 

 perch. (3) When flying from one perch to another . . . the bird 

 would sometimes end its flight in a rapid swoop down below the 

 level of the new perch, then rise up above it and down on it, so 

 that the trajectory was a shallow S-curve. A quite different display, 

 directed toward a female was seen once." In this the male "began 

 flying round her with a slow flapping flight during which the wing- 

 beat was deep and so slow that the wings were easily visible. The 

 appearance in fact was very like that of a large black and white 

 butterfly."
