[[underlined]]Cyanerpes[[/underlined]], May 14, 1963, IV

Again ♂ approaches ♀ with St & Buzzes. ♀ flies away. Instead of following with R's, ♂  remains where he was. Goes into extreme St, bill nearly vertical, with BL, quite a lot of BF, TV, and [[underlined]]utters series of PN's in this posture[[/underlined]]. Wings slightly out, horizontally, and [[underlined]]Q'd[[/underlined]] slightly at same time! ♀ doesn't respond 7:13

♂ certainly seems to be highly motivated!

♂ occasionally approaches and supplants  ♀, with St & R's.

Both birds utter occasional single CN's almost all the time, even in close association with elaborate displays, but I have been too busy to record them this morning.

One or both bird(s) utter(s) Buzzes, without special postures or movements, when Chachalaca lands on top of their cage.

♂ again approaches  ♀ with St & Buzzes, switching to R when she retreats.

♂ somewhat less active now 7:25. Preening. ♀ flying about more actively than before. Uttering occasional CN's.

♂ again approaches  ♀ with St and Buzzes. ♀  again retreats. ♂ stops display and BW's as soon as she leaves, instead of following her with R's. Is he getting discouraged? 7:33

♀ goes down to feed. ♂ remains perched about 3 ft above her. He utters 2 or 3 PN's. Also a number of soft "CN"s

There are definitely 2 types of "CN"s. Commonest type is loud, hard and metallic "Trit" This is the type that is accelerated into R. Must contain a hostile component, but is is uttered so frequently (these birds are so nearly constantly hostile) that it may also function as a "real" contact note. Probably homologous with the SHN's of other species. I shall call it by the same name. It is probably an example of a late stage
