Mixed Diglossini, Feb 11, 1964, VII
[[circled]] 15 [[/circled]]

[[underlined]] Diglossopis [[/underlined]]-like. Little in the way of a hook or an upturn.

[[margin]] Coer [[/margin]][[image - drawing of bird's head]] Comme ça

[[margin]] Coer [[/margin]] while I am writing this, what is obviously the same bird returns to same tree twice more. Doesn't utter metallic "feeet"'s either time. But does sing in the same ways as the "Coer" did earlier. Also utters lots of non-metallic feeeee" and "feeeet" Notes which sound very Cy-like.

[[margin]] Coer [[/margin]] It is obvious, I think, that no more than one blue diglossine has visited this tree this morning during the period I have been watching it. The bird I identified as a Cy and the bird I called "Coer" must be one and the same. It may be either a "real" Coer, a [[underlined]] glauca [[/underlined]], or a juvenile Cy. Although its physical appearance might suggest the latter, I would be surprised if a juvenile were so vocal and uttered so many patters unlike those of the adults of its own species.

[[margin]] Coer [[/margin]] According to my notes, [[underlined]] glauca [[/underlined]]does not occur in this area. So I think that this bird must be an adult [[underlined]] coerulescens [[/underlined]]. I shall continue to call it "Coer" for the time being at least.

[[margin]] Coer [[/margin]] The presumed Coer seen yesterday, with a pretty light bill, may have been a juvenile. 

[[margin]] Coer [[/margin]] Incidentally, both the presumed Coers seen today and yesterday looked moderately large. Perhaps larger than Cys.

[[margin]] Cy [[margin]] Hear what sounds like Cy singing immediately. Then the bird shuts up.
