68 Rhamphocelus [[Ramphocelus]], Mar. 26, 1961 II more. How does the DWS of this species differ from the "Keeyoo" song in function(s) and causation? Could the "Keeyoo" song be comparable to the "Trit" & Q performance of male Brown-capped Bush-tanagers, and the DWS comparable to the "S" patterns of Brown-capped Bush-tanagers????? Rhamphocelus [[Ramphocelus]], I May 17, 1961 Barro Colorado I watched a male Sangre singing "Keeyoo"song this morning. Almost steadily for 1/2 hour after dawn. By himself, throughout the whole performance. (I think this male is seated, but his female did not appear while he sang.) The male sang from 3 different perches, in the same area. Returned several times to two of the perches. Always high and exposed. [[image - sketch of bird, red arrows point to the top of the head, the beak, and belly.] Rather extreme "Keeyoo" singing posture. Tail not forward in this drawing. He always sat in a quite erect sitting posture. Looking quite "high" and elongated at first (possibly with the neck stretched slightly higher than in the accompanying drawing) - and then gradually relaxed, more or less as the continued to sing, until he was sitting in a very "dumpy" posture.
