Cyanerpes, Dec 1, 1957, II. 16

course one occurred today. Given by one of the birds when the ♂ landed suddenly beside the ♀. And, of course, I didn't manage to catch any of the details!
   The ♀ also did one G during feeding. Probably directed at, and provoked by the ♂ (although it is possible that the ♂ Rio Gordo was the culprit instead). Just put head up and opened bill

This looked almost like an intention movement of a Wh Complex performance; and I rather got the same impression before, once or twice, when the birds were in the small cage.
One thing I have noticed, whenever the birds seem to be disturbed in any way, by my approach or a visitor, they both, and particularly the ♂, peck at the bands on their legs very frequently & vigorously. Redirection?
As further evidence to support the theory that the HCN contains a relatively stronger escape component than the ordinary CN, I should mention that a visiting ♂ this morning gave a lot of HCN's in the tree (with smooth crown as usual) and then changed to CN's when it flew down and tried to get at the birds inside the cage.
The ordinary CN is certainly the usual form given by the captive ♂ flying about excitedly inside the cage when visitors are present.
I am now rather tending to the conclusion that visiting must be a hostile pattern ―although general gregariousness may be involved in some of the patterns that occur, at least affecting the form they usually take.
