Approximately a minute later, see single Blue Diglossa in same bush.  
[[margin, in red]] Cy 16 [[/margin]]
Almost certainly [[underlined]] Cy [[/underlined]] [[pencil and red checkmarks]].  Silent and alone.  Flies off, 
[[margin, in red]] Coer [[/margin]]
past tree in which Coer is still singing as before.  Cy passes about 30 ft below Coer.

[[margin, in red]] Cy Albi Coer [[/margin]]
So Cy and Albi territories seem to overlap here (I think I established this in 1962).  Cy and Coer territories may also overlap.

Shortly after the Cy flies by, the nature of the Songs from the fruit tree [[underlined]] appears [[/underlined]] to change.  Intro notes become more like "soooo", and become relatively louder.  And the twitter part of the Song phrases 
[[margin, in red]] Coer? [[/margin]]
becomes more Cy-like - very much like the shorter Cy phrases at the Paramo de Guasca.  I think that a Cy [[underlined]] must [/underlined]] have gone up in this tree 
[[margin, in red]] Cy? [[/margin]]
and begun to sing.  But I can't see the bird.

When these Cy-like phrases begin, the typical Coer phrases stop.  No overlap.

If there was a Cy in this tree, it did [[underlined]] not [[/underlined]] feed on fruits.  
[[margin, in red]] Cy? [[/margin]]
I would have seen it moving if it had fed.

Anyhow, a few minutes later, the Cy type phrases stop.  
[[margin, in red]] Coer [[/margin]]
Typical Coer phrases begin again.  And now I see an undoubted Coer feeding on fruit again.  Also definitely see that this is the bird which is uttering the Coer-type phrases. See  mandibles moving.

[[margin, in red]] Coer Cy [[/margin]]
The Coer has been ranging 25 - 40 ft above ground in this tree.  If there was a Cy in the tree, it stuck to 20 - 25 ft level.

[[margin, in red]] Coer Cy [[/margin]]
This evidence, such as it is, fully supports the hypothesis that the mutual avoidance, inhibition, mechanisms are fully operative in the Cy-Coer relations here.

[[margin, in red]] Coer [[/margin]]
8:00 am.  Coer still in tree.  Still uttering typical Coer type phrases
